Key Material Characteristics of Copper:

Excellent Electrical and Thermal Conductivity: 

Its electrical conductivity is second only to silver, and its thermal conductivity ranks among the top metals, making it a preferred material for 

electronics and thermal applications.

Good Ductility and Machinability: 

It is soft and easy to forge, roll, stretch, and weld, allowing it to be processed into extremely thin copper foil or extremely fine copper wire.

Strong Corrosion Resistance: 

It is stable in dry air and pure water, and an oxide film forms on its surface to protect the inner metal layer. It is only easily oxidized and blackened in 

humid, sulfur-containing environments.

Easy Alloying: 

It can form alloys with metals such as zinc, tin, and nickel to form brass, bronze, and cupronickel, optimizing properties such as strength and wear 

resistance.
