Copper

Key Features: 1. Silver-like appearance (high luster and tarnish-resistant)
2. Excellent antimicrobial properties (suitable for medical/food-grade applications)
3. Good elasticity & wear resistance (suitable for elastic components)
4. Seawater corrosion resistance (preferred for marine equipment)

Key Features: 1. High elasticity & ductility (moderate yield strength)
2. Strong corrosion resistance (resistant to salt spray and sweat)
3. Good electrical/thermal conductivity (about 15% of pure copper)
4. Non-magnetic (ideal for electromagnetic shielding applications)

Key Features: 1. Excellent plasticity (good cold and hot workability) 2. Relatively high strength (tensile strength ≥ 300 MPa) 3. Good electrical and thermal conductivity (about 30% of pure copper) 4. Resistant to atmospheric corrosion (but not resistant to dezincification or acidic media)
