Have a better electrical conductivity, thermal conductivity, corrosion resistance and processing performance, can be welded and brazed. But contains lower electrical conductivity, thermal conductivity impurities, higher oxygen content, more likely to cause “hydrogen disease”, can not be at high temperatures (such as > 370 ℃) reducing atmosphere in the processing (annealing, welding, etc.) and use.
