Copper's core properties are excellent electrical and thermal conductivity, good ductility, and strong corrosion resistance, making it a widely used basic metallic material.

一、Core Properties:

Outstanding Electrical and Thermal Conductivity: Its electrical conductivity is second only to silver, and its thermal conductivity is also among the highest of metals, making it a core material in the electrical engineering field.

二、Excellent Ductility: 

It can be easily stretched, rolled, and forged, and can be processed into extremely fine wires or extremely thin copper foils.

三、Good Corrosion Resistance: 

It is stable in dry air and fresh water environments, and an oxide film forms on the surface to protect the interior from further corrosion.

四、Easy to Process and Weld: 

It can be formed through various methods such as casting, stamping, and machining. Welding is easy, and the joint performance is stable.

五、Secondary Properties: 

Has a certain strength: Pure copper has moderate strength; the strength is significantly increased after adding elements such as zinc and tin to form alloys.

六、Magnetic Properties: 

It is a paramagnetic material with weak magnetism, which does not affect most applications.

七、Unique Color: 

Pure copper is purplish-red; after oxidation, a bronze-colored oxide layer is formed on the surface, combining practicality and decoration.
