T2 T2 copper material copper introductory material Name: T2 Copper Standard: Range (GB/T5231-2001) Features and Applications: There are good electrical conductivity, thermal conductivity, corrosion resistance and workability, welding and brazing. With lower conductivity. Less thermal conductivity impurity traces of oxygen has little effect on the conductivity, thermal and processing properties, but lead to a "hydrogen disease", not processing (annealing at a high temperature (e.g.> 370 °) in a reducing atmosphere welding, etc.) and use. Copper with a series of copper, so named because was purple. It is not necessarily a pure copper, and sometimes a small amount of deoxygenated elements or other elements to improve the material and sexual performance, it is also classified as a copper alloy.
