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.
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 tubesHigher softening temperature than Cu-DHP, so the tube keeps its taper longer at the meniscus. Recommended for high-speed billet casters.
CuAg copper mould tubesHighest strength and wear resistance. For bloom moulds, high casting speed and long campaigns where tube life is the main cost driver.
CuCrZr copper mould tubesWe manufacture copper mould tubes according to customer drawings, mould dimensions, casting radius, material requirements and cooling specifications.
