Copper Materials for Mould Tubes

The copper grade decides how long a tube lasts and how fast you can cast. We supply all three industry grades and help you choose.

Cu-DHP

TP2 · phosphorus deoxidized copper

Economical grade for standard billet casting at normal speed. Good thermal conductivity, easy to machine, the most common choice for R6 and R9 tubes.

Cu-DHP copper mould tubes

CuAg

Silver-bearing copper · 0.08–0.12 % Ag

Higher softening temperature than Cu-DHP, so the tube keeps its taper longer at the meniscus. Recommended for high-speed billet casters.

CuAg copper mould tubes

CuCrZr

Chromium zirconium copper · precipitation hardened

Highest strength and wear resistance. For bloom moulds, high casting speed and long campaigns where tube life is the main cost driver.

CuCrZr copper mould tubes
