TPC(Tough-Pitch Copper Billet)
Touch-pitch copper billet (ASTM Standard: C11000) has oxygen concentration of 400ppm or less, and is a material including very small amount of bismuth (Bi), lead (Pb) and titanium (Ti). The product has outstanding electrical and thermal conductivity along with excellent electro-thermal property, corrosion resistance and weather resistance, and is widely used as electric and chemical materials.
The Company’s tough-pitch copper billet uses only the electrolytic copper and high-quality scrap to have high purity, and outstanding refining and deoxidization technique are used to have excellent machinability. Especially, high-grade tough-pitch copper billet has low oxygen content to have smooth surface and low blister to be used for lathe processing.
