Selection Criteria
- Corrosion resistance
Choose alloys with higher corrosion resistance for marine or outdoor environments, such as bronze and copper-nickel alloys
- Electrical/thermal conductivity
Pure copper or copper-silver alloys are ideal for applications requiring high conductivity
- Strength and durability
For structural applications, stronger alloys such as aluminum bronze or brass are preferred
- Machinability
For precision and large-scale manufacturing, leaded brass or machinable copper alloys are recommended for better machinability
Applications
- Electrical and electronics industry: Used in applications ranging from household wiring to large power transmission lines in power plants
- HVAC: Essential components like refrigerant piping, evaporators, and condensers
- Building and infrastructure: Roof materials, curtain walls, door and window frames, and other architectural features
- Automotive manufacturing: Engine cooling systems, brake systems, electrical wiring, and more
- Marine engineering: Components resistant to seawater corrosion such as ship hulls and propeller shafts
- Medical equipment: Surgical instruments, dental tools, and other medical devices
- Telecommunications: Copper shielding for fiber optic communication systems
