Shanghai Metal Corporation is a leading Chromium zirconium copper bar manufacturer and supplier.
The chromium-zirconium copper rod (CuCrZr) is composed of three kinds of metals, which has high hardness, good wear resistance and explosion resistance, and high softening temperature (hardness >75HRB; after 2 hours at 550 °C, the quenching cooling is not lower than the original hardness. More than 15%; the average value of three-point conductivity is ≥44MS/M measured by eddy current conductivity meter.) It is a good welding material with good crack resistance. Common grades are QCr1-0.15 and QCr0.6-0.4. , QCr0.5, C18150, C18200 and so on.
