Copper Alloys We Process

Pure Copper (C101, C110)

Pure copper is prized for its unparalleled thermal and electrical conductivity. It is commonly used in components where efficient heat or electrical transfer is essential such as heat exchangers. Heat treatment processes like annealing optimize its ductility, making it easier to shape and form while maintaining its inherent properties.

Pure Copper Hardness Ranges

After annealing, pure copper typically achieves a hardness of about 40 HRF, depending on the specific application and processing requirements.

Copper-Nickel Alloys (C706, C715)

Copper-nickel alloys offer exceptional resistance to corrosion, especially in marine and chemical environments. Their relative strength and durability make them ideal for heat exchangers, marine components, and other applications exposed to harsh conditions. Annealing enhances their machinability and formability.

Copper-Nickel Hardness Ranges

Annealed copper-nickel alloys generally achieve a hardness of around 15 HRB, providing a good balance of strength and corrosion resistance.

Chromium Copper (C182, C184)

Chromium copper is a high-performance alloy known for its excellent electrical conductivity and moderate strength. It is widely used in welding electrodes, circuit breakers, and other high-stress electrical components. Solution treating and aging improve both its strength and hardness.

Chromium Copper Hardness Ranges

After solution treatment and aging, chromium copper typically reaches a hardness level of about 60 HRB, ensuring superior wear resistance and electrical efficiency for critical applications.

Tellurium Copper (C145)

Tellurium copper is a free machining copper, making it ideal for intricate components like electrical connectors, switchgear, and semiconductor tools. Stress relieving stabilizes its properties, ensuring dimensional accuracy.

Tellurium Copper Hardness Ranges

Stress-relieved tellurium copper generally achieves a hardness of around 40 HRF, providing the ideal balance between machinability and performance.

Heat Treatment Processes for Copper

Solution Treating and Aging

Solution treatment enhances copper’s mechanical properties by dissolving soluble phases and locking them in place through rapid cooling.

Annealing

Annealing, a common type of solution treating, reduces hardness, enhances ductility, and relieves internal stresses in copper components. This process ensures easier machinability and longer-lasting performance in demanding applications.
