Purpose:
High purity, fine tissue, and low oxygen content. There are no pores, sand holes, looseness, good conductivity, and high surface accuracy of the mold produced by electrical erosion. After heat treatment, the electrode has no directionality, suitable for precision and fine punching, and has good thermal conductivity, processability, ductility, corrosion resistance, and weather resistance. It has good conductivity, thermal conductivity, corrosion resistance, and processing properties, and can be welded and brazed.

 

Characteristic
It has good conductivity, thermal conductivity, corrosion resistance, and processing properties, and can be welded and fiber welded. There are few impurities that reduce conductivity and thermal conductivity. Trace amounts of oxygen have little effect on conductivity, thermal conductivity, and processing properties, but can easily cause "hydrogen disease". It is not suitable for processing (annealing, welding, etc.) and use in a high-temperature (such as>370 ° C) reducing atmosphere

Pure copper is a rose red metal with a purple color after the formation of a copper oxide film on the surface. Therefore, industrial pure copper is often referred to as purple copper or electrolytic copper. Fire refining can yield 99 to 99.9% pure copper, and electrolysis can achieve a purity of 99.95 to 99.99%. The density is 8-9g/cm3, and the melting point is 1083 ° C. Pure copper has good conductivity and is widely used in the manufacturing of wires, cables, brushes, etc; Good thermal conductivity, commonly used to manufacture magnetic instruments and meters that require protection against magnetic interference, such as compasses and aviation instruments; Good plasticity, easy to hot press and cold press processing
