4. What is the application of copper alloy ?

Electrical Connectors: In aerospace, automotive, and electronics (e.g., relays, switches).

Spring Components: High-stress springs in harsh environments.

Marine Hardware: Corrosion-resistant parts for saltwater applications.

Aerospace Components: Bearings, bushings, and structural parts.

Tooling: Dies, molds, and fixtures requiring high hardness and wear resistance.

5. What are the advantages of copper alloy ?

High Strength & Hardness: Comparable to steel but with better ductility and formability.

Excellent Corrosion Resistance: Resistant to seawater, acids, and atmospheric corrosion.

Good Conductivity: Moderate electrical and thermal conductivity (suitable for applications where non-magnetic or non-sparking properties are needed).

Heat Resistance: Maintains mechanical properties at elevated temperatures (up to ~300°C / 572°F).

Non-Magnetic & Non-Sparking: Ideal for sensitive environments (e.g., oil/gas, explosive atmospheres).

Weldability & Machinability: Can be welded and machined with proper techniques.
