Copper

Key Features: 1. Excellent electrical and thermal conductivity (comparable to pure copper, electrical conductivity ≥ 90% IACS) 2. Outstanding corrosion resistance (resistant to atmospheric and seawater corrosion, and dezincification) 3. Good plasticity (suitable for complex molding) 4. Relatively low strength (tensile strength ≥ 250 MPa)

Key Features: 1. Ultra-high strength (tensile strength up to 1,400 MPa after aging) 2. Excellent electrical and thermal conductivity (20–60% IACS) 3. Non-magnetic and spark-resistance (suitable for flammable/explosive environments) 4. Fatigue and corrosion resistance (long-term stability in performance)

Key Features: 1. High strength and hardness (tensile strength ≥400MPa) 2. Excellent plasticity (suitable for complex cold molding) 3. Low cost (high zinc content provides economic benefits) 4. Atmospheric corrosion resistance (prone to dezincification; it is not suitable for acidic environments)

Key Features: 1. High strength and hardness (tensile strength ≥ 350 MPa) 2. Excellent cold workability (suitable for deep drawing and complex molding) 3. Good electrical and thermal conductivity (about 28% of pure copper) 4. Cost-effective (cheaper than high-copper brass)

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)
