At peresnt,Deoxidized phosphorus copper(TP2),Silver-bearing copper(CuAg0.1) and Cu-Cr-Zr are normally selected as the material to produce copper mould tubes

Metal Mould 2-CuAg

Adding 0.08%-0.12% silver during copper ingots melting will increase the re-crystallization temperature of copper by 100 °C , which will increase the heat stress and anti-abrasive property of copper mould tube interior surface, showing better heat-resistant property than Tp2.
