square copper mould tube, rectangular copper mould tube, round copper mould tube, beam blank copper mould tubes and other non-standard copper mould tubes.
Improve the manufacturing process of mold copper tube, and reasonably select the taper, innercavity curve, wall thickness and other parameters of mold copper tube; Optimize the structure of mold and improve the performance of mold sealing rubber material;
Metallurgy of Copper Mould Tubes | |||
Material | Cu-DHP | Cu-Ag | Cu-Cr-Zr |
High Phosphorus Deoxidized Copper | Cu-Ag (Cu-0.1Ag) | Cu-Cr-Zr (Cu-0.6Cr-0.15Zr) | |
Properties | Normal Deoxidized Copper | Through the addition of about 0.1% silver,strength is significantly enhanced with no loss in thermal conductivity | Cr and Zr precipitation hardening provides this alloy with high strength, high resistance to heat, and thermal conductivity |
