01. Tough Pitch Copper

General Description

The copper is gained with 0.02-0.04% of O2 remained and the content of H2 in copper reduced during casting process and impurities of As, Bi and Sb etc oxidized, thus its conductivity and ductility being enhanced. The copper, with copper content over 99.90% and electric conductivity over 98% produced with outstanding raw material, has good electric and heat conductivity and thus is used in a variety of applications in electric industry.

02. Phosphorus Deoxidized Copper

General Description

Phosphorus Deoxidized Copper are produced in such a way that they are deoxidized with Cu-P to the extent where the oxygen content is reduced below 0.01% and P content at approx. 0.02% during casting process, and thus has no hydrogen embritlement in high temperature, does not absorb oxygen, and has a high softening temperature appropriate to welding work. It has good workability and color.
