C1100 is copper
Brand: C1100
Standard: GB/T 4423-1992
Characteristics and scope of application:
It has good electrical conductivity, thermal conductivity, corrosion resistance and processing properties, and can be welded and brazed. Contains less impurities that reduce electrical conductivity and thermal conductivity, and trace amounts of oxygen have little effect on electrical conductivity, thermal conductivity and processing properties, but it is easy to cause "hydrogen disease" and should not be processed (annealed, welding, etc.) in a reducing atmosphere at high temperatures (such as>370℃).
