Description
C18150 Chromium Zirconium Copper Rod — RWMA Class 2 High-Conductivity Bar for Welding & Industrial Applications
C18150 Chromium Zirconium Copper Rod is a precipitation-hardened copper chromium zirconium alloy for thermal and electrical load-bearing working conditions. Established in 1997, Dongguan Jiaye Dingsheng boasts 25+ years of copper alloy production experience. This alloy rod reaches 450–550 MPa tensile strength and 75–83 HRB hardness, with 80%+ IACS conductivity and 320 W/(m·K) thermal conductivity. It maintains stable performance under 500°C working temperature. Available in 2–200mm diameters, the product complies with ASTM B929, RWMA Class 2 and DIN 17666 standards, with complete MTC test reports and batch traceability provided for each shipment.
What Is C18150 Chromium Zirconium Copper Rod?
In high speed manufacturing, standard copper alloys often fail by softening and deformation at temperatures over 200°C. This causes electrode deformation, frequent dressing of the tip and variable weld quality, all of which contribute to increased downtime and expense.
This is solved immediately by C18150 Chromium Zirconium Copper Rod. An alloy with a stable microstructure resistant to grain development is developed by adding 0.5–1.5% Chromium and 0.05–0.25% Zirconium to a copper basis and processing by solution heat treatment and controlled ageing. This results in a rod that can withstand constant temperature cycling without losing its hardness and form – something that pure copper or regular C18200 cannot consistently achieve.
C18200 is the same as C18150, except with the addition of Zirconium. It boosts the softening temperature and resistance to deformation, which immediately translates into longer electrode life and fewer production interruptions.
