You should try electrical way because that's the way how we weld them.😁Generally those tips contain 505-85% silver. If they contain tungsten, the color is darker.
Great video. I have seen people take places and use the other type of torch. They would melt and drip off. No idea what that was on those unless it was titanium
Majority of those contacts are around 85 percent silver definitely. I've been extracting silver from them alot lately. You shouldn't give up on them so easily. Most of them don't necessarily melt. You have to get them considerably hotter than silvers melting point and then the silver will bleed out of the contact. And the reason why you couldn't get them off of the copper part was because the solder is of a high silver content, therefor u have to get them glowing hot to melt the solder. But yea.. most of those contacts are really nice ones. U could of got at least a pound of pure silver out of them for the looks of the amount u have there.
Oh boy........yeah I've had a couple comments about that. "Safety shoes" are a little overkill for this kind of work. Still have all 10 toes so we're crushing it over here!!
Heavy duty ontacts are usually silver 60% tungsten 30% and other metals such as copper rhenium and palladium making the last 10%. Smaller ones are 90% silver and 10% copper.
Older contacts has up to 98% silver. I send mine to a refinery. One dollar per ounce. They send back bars are coins your choice. Hope this helps. It is cheaper then doing your on refining . To me it is.
A lot of contacts are tungsten. Tungsten melts at 6150 f. I’ve been saving contacts for years and just found out from this video that I’ve been wasting my time. Glad I didn’t try and melt them down.
It is a known fact in the Electrical Trade that "Silver" electrical contacts have very little silver in them, the main reason being that high levels of silver can not take the mechanical ware and also the arcing in use.
The easiest way to remove the gold from the pins is chemically. All melting the pins will do is make an inquarted allow of gold and copper. Thats if the base metal is copper. If it was, you can still recover the gold by placing the allow in nitric acid. It will dissolve the copper and leave the gold behind as powder
Most likely those big bits are brass if non magnetic a scratch test at the start would tell. The buttons you were trying to melt off may contain silver but heat the back of it instead.
I think maybe that "solder" you knocked off at the beginning (with the torch) were the actual contact points on those pieces of metal, therefore that would be the silver content?
Youde be better off dissolving the silver with Nitric acid, but You really got to know what you're doing with acids. It will dissolve all silver & copper and leave the tungsten alone. Then all you have to do Is drop a bar of copper in the acid and drop all the silver. That's when you melt. Full process can be found in UA-cam.
No way I'm messing with acids. No interest. Will be collaborating with another channel soon since he uses the chemicals. He'll get the silver then I'll melt it.
I put the torch rig in a vise to hold it. I hold the contact with a pair of needle nose pliers heat up one side at a time till the copper bit it dull orange then I tap the pliers on a coffee can filled with water. The silver bit will fly right in the water. You will ruin those needle nose so use a crappy set.
I do these contacts all the time. Very simple process to a nice fat bar of 999 silver. Aldo that bag of gold pins can also be refined for a small gold button.
@@SkullerMetals lol you caught me. Yeah i love doing this as a hobby. Been doing it for quite some time now. Maybe one day i get enough nerves to make videos. Thats the part thsts way outa my league lol.
Some are tungsten but the large square ones are silver-cadmium contacts.. When heated to hi temps Cadmium release extremely toxic fumes that can poison your body and do long-term damage so please use proper ventilation and ppe... The silver-cadmium contacts can be dissolved in boiling sulfuric acid(drain cleaner) then the silver precipitated out using hydrochloric acid.. ⚠ 💀💀this process is extremely hazardous!!! Uses extremely crossive acid and will produce toxic and corrosive fumes that will kill you if inhaled (will literally melt your lungs) 💀💀💀 ⚠
Electric contacts use a really strong solder. MAPP gas does burn hot enough, but you might have better luck if you position some duct seal putty around it to hold the heat in, or some fire bricks.
Melting gold plated pins makes it harder to extract the gold. You should always research the material before you heat, grind, or use chemicals on it. Let's stay safe and live longer. Good luck and hope you are safe.
It's Tungsten. You will never melt it and its not valuable. You didn't keep your torch on the contacts long enough to get the silver contacts off. Get your torch stationary so that you can hold the metal in one hand and your screwdriver in the other hand toscrape them off. . The contacts are typically on silver plated copper when they are that size. I've done hundreds.
This is the third time I've commented on this video, but it keeps getting deleted because I was trying to send a link, or describing a website without a direct link 😣. Bottom line is those contacts are an alloy of silver and tungsten. No wonder they didn't melt. 👍
@@SkullerMetals, Well yes and no. When alloys are made they have completely different properties to the original metals. One common example is bronze, being copper and tin. Tin is quite soft, a lot softer than copper, but bronze is harder than copper even though it's alloyed with tin, a softer metal. Strange.
You might of melted the crucible most of the cheap ones can only handle med temps to melt copper you sure did have that piping hot I learned this after my first day and had to buy a new one med -low heat is better and long burn time with borax added after it’s all melted
Hey there, why don't shoot me an email at skullermetals@gmail.com and let me know what you're thinking. I'm always open to something different and interesting.
@@SkullerMetals avoiding acids doesn't necessarily make you safer when you make a video melting these without knowing what metals they consist of, reading up and then doing a safe acid process would have been the best way forward realistically. there are processes I do involving only 10% vinegar/acetic acid and hydrogen peroxide, the acid alone isn't enough to even cause me skin irritation (obviously you must still be careful and if you get it in your eyes well that will hurt lol) and that is able to dissolve copper and leave behind gold foils or powder.
@@MortallyMysterious There are only a couple ways to find out "what a metal consists of - do what I did or get it tested on an XRF machine which would cost me money. I was told they were silver so I wanted to find out. I don't see what the issue is here - people do trial and error on stuff all the time.
@@SkullerMetals I enjoyed your video, the trial and error was good. I was just meaning to leave my thoughts on it. I also cannot afford xrf equipment or testing so for the most part i've done the same in the past. It seems like both you and I could have been better off fumes wise with a bit more internet digging and research about different contacts, I have tried cupelling smaller ones from relays and found out about the cadmium risk and have been trying to figure out better ways of refining, seemingly weaker acid solutions like acid peroxide mixes are a really good place to start and could be great for lower grades of silver stuff, these other noble metals need aqua regia or concentrated nitric, now I cannot get these nor am I comfortable messing with stuff that corrosive at this point. However, something like hcl 20%-30% and some copper II Chloride (add hydrogen peroxide 3-6% to accelerate if desired) should work well on stuff that is showing copper if you want to try that.
@@SkullerMetalswhat about electrolysis? Streetips shows how to get the silver from impure contacts. Look it up. You can then grow silver crystals to melt in the oven lol.
Ok for one that's a shitty thing to say. You must be a miserable person. Secondly, watch some other vids, you might like them. I'll be sure to mention you in my next vid for sure - you won't want to miss that one.
Yup the easiest way melt them all then slowly electrolyze with CuSO4. The Zn etc stays in solution, silver forms a mush with any tungsten or pgms. Treat the mush by rinsing well and then boiling in NaOH to remove the tungsten then disolve what's left in nitric acid to get the Ag as AgNO3. The salt is a bit more valued than actual silver if marketed right. The black powder that is left is mostly palladium ❤
your too slow you get it melted the you put down the torch grab your screw driver pour a cup of coffee talk on the phone pet the dog then by the time you get your screw driver onto the work sirface its already cold
I cut off the silver tabs with a thin cutting disc on my grinder. You really have to pay attention when doing this to ensure you don't have any copper still attached. On a lot of those contacts you CAN remove them with a torch using MAP gas. It takes a couple of minutes but eventually you can slide them free with a knife blade.
@@SkullerMetals its not all tungsten, i've cooked plenty of them. if you file off a corner or cut them in half with bolt cutters they will melt, however the kind you got there look like the suckers that are rich in platinum as they're high amp contacts. Any high amp contacts don't use silver as they'll melt... so even if you file the whole outside of it and can melt copper off them before they melt, its platinum and they can be rich in it from personal experience. Extremely difficult to melt
@@bevsman3284 no need to remove copper lol... it melts off first... cook copper off, cool, bolt cutters to slice them, cook clean contacts and they're incredibly hard to melt still and i assure its not lots of tungsten.

Hey thanks Harry!
Twist it! Hold from top with small cutters above silver and also below it with another pair. Twist longer side and it pops off super easily.
Yep I've seen scrapitall do it that way which is ok for small ones I guess

Hey thanks Mike!!
I think they fished you in! Great video!
often there is a lot of sintered tungsten in those contacts, or some are silver plated tungsten.
Interesting video. Did you figured out what the silvery stuff was? May a friend of yours has an XRF?

Ya silver is very soft
Probably tungsten?? I've got a bunch of those, too. ☹
Your guess is probably better than mine. I mean it didn't even start to melt them. I probably had the temp up to 2100 F.
That's what I was thinking too. Tungsten has a super high melt point
This video brought back memories lol. That green flame is toxic as it gets. It takes extreme temp to brick electrical contacts.
Yeah I wont be doing that again. Thankfully I'm still alive and kicking.
Gratz on reaching 2 k
Thanks Philip!
Great video
Education at its finest. Now you know they aren’t silver. So you won’t have to try that experiment again. And some bonus bricks 🎉🎉

What do you do with your melted copper
So far I'm just stacking it. Making a copper wall in my basement. :)
Study up on metals, gotta lot to learn but it's fun.
If I don't save silver contacts can they go in clean copper /brass
I really don't know.
@SkullerMetals thank you
Bummer that the one stuff didn't turn out good atlease you got a great copper bar and a skull out of it thanks for sharing skuller metals

When you was dropping them they had a thud sound and silver has a ting sound when dropped
Silver plated those piece where tungsten , thats why they did not melt at 950°C , that is my guess, good job anyway

A celebration for 2K🎈🎈🎈
Thank you kind lady! 😉
That looks like a lot of work
Use nitric acid it will turn silver into solution

Borax and baking soda then use 4 or 5 good iron nails❤❤❤
