Copper

Copper is a high-performance metal known for its excellent electrical conductivity, thermal conductivity, and corrosion resistance. It is widely used in applications requiring efficient heat dissipation and reliable electrical performance.

Pure copper and copper alloys are commonly used in industries such as electronics, energy, and industrial equipment. Due to its softness and ductility, copper can be challenging to machine, but it allows for high-precision components when processed correctly.

Copper grades such as C110 (electrolytic tough pitch copper) are widely used for electrical applications, while oxygen-free copper (C101) is preferred for high-conductivity and high-purity requirements.

At Modo Rapid, we provide precision CNC machining services for copper components, ensuring tight tolerances, excellent surface finish, and reliable performance in demanding applications.

Material Comparison

Compared to brass, copper offers significantly higher electrical and thermal conductivity, making it more suitable for electrical and heat transfer applications. However, brass provides better machinability and is often preferred for precision mechanical components.

Compared to aluminum, copper provides superior conductivity and heat dissipation but is heavier and more expensive.

Compared to stainless steel, copper offers much better thermal and electrical performance but lower strength and wear resistance.

Material selection depends on the balance between conductivity, mechanical strength, and cost.
