High purity copper is an indispensable and precious material in atomic energy, rockets, missiles, aviation, aerospace, and metallurgical industries. High purity copper has strong heat absorption ability, stable mechanical properties, high melting point, and high temperature resistance, making it the best material for neutron reflection layers in atomic reactors. In the metallurgical industry, it is an additive for alloy steel and is also used in refractory materials and special glass, integrated circuits, antennas, and many other aspects.
Pure copper powder, known as purple copper powder or red copper powder, the purity of copper is more than 99%.
Brass powder, also known as copper-zinc alloy powder, the main raw material Cu + Zn total purity of 99% or more.
Bronze powder, also known as copper-tin alloy powder. Lead-free bronze powder and tin bronze powder.
