Slide 1: Introduction to Nonferrous Metals
Lecture Contents:
Nonferrous metals are metals that do not contain iron in appreciable amounts. They are generally more resistant to corrosion, lighter, and possess unique electrical and thermal properties.
Key Nonferrous Metals: Aluminum, magnesium, titanium, copper, and their alloys.
Common Uses: Aerospace, automotive, electronics, and construction industries due to their high strength-to-weight ratio and corrosion resistance.
Example: Aluminum is widely used in the automotive industry for reducing vehicle weight while maintaining strength.
Slide 2: Aluminum and its Alloys
Lecture Contents:
Properties of Aluminum:
Density: 2770 kg/m³ (0.10 lb/in³).
Tensile Strength: Pure aluminum has 90 MPa (13 kpsi), but alloying and cold working can enhance it.
Modulus of elasticity: 71.7 GPa (10.4 Mpsi), about one-third the stiffness of steel.
Applications: Sand casting, die casting, extrusions, and structural applications.
Corrosion Resistance: Forms a protective oxide layer naturally, enhanced by anodizing.
Example: Duraluminum (2017 alloy) is widely used in aerospace due to its heat-treatable properties, providing enhanced strength.
Slide 3: Magnesium and Titanium
Lecture Contents:
Magnesium:
Lightest structural metal with a density of 1800 kg/m³ (0.065 lb/in³).
Low strength but excellent strength-to-weight ratio.
Used in aircraft and automotive industries where weight reduction is critical.
Titanium:
Strong as moderate-strength steel but weighs only half as much.
High corrosion resistance and high-temperature strength.
Used in aerospace, military, and biomedical applications.
Example: Titanium is essential in building aircraft frames due to its strength and corrosion resistance at high altitudes.
Slide 4: Copper and Copper Alloys
Lecture Contents:
Copper Alloys:
Brass: Copper alloyed with zinc. Variations include low-zinc brass (for jewelry) and high-zinc brass (for cartridge cases).
Bronze: Copper alloyed with elements like tin or phosphorus, providing fatigue resistance, good for springs.
Applications: Marine hardware, electrical connectors, and architectural elements.
Special Alloys: Beryllium bronze offers high strength and corrosion resistance but at a higher cost.
Example: Admiralty brass (28% zinc, 1% tin) is used in marine applications due to its excellent corrosion resistance in seawater.
