C11000/T2 is pure copper, also known as copper, copper has good electrical conductivity, thermal conductivity, corrosion resistance and processing performance, can be welded and brazed. Contains less impurities to reduce electrical conductivity, thermal conductivity, trace oxygen has little effect on electrical conductivity, thermal conductivity and processing properties, but it is easy to cause "hydrogen disease". It is not suitable for processing (annealing, welding, etc.) and use in a reducing atmosphere at high temperature (such as> 370 ℃).
