C18200 RWMA Class 2 Chrome Copper is a heat treatable, corrosion resistant alloy which combines high electrical conductivity with high strength. Rwma Class II chrome copper is a superior resistance welding electrode material specifically recommended for high level production spot welding and seam welding of clean mild steels, low alloy steels, low conductivity brasses and bronzes. Our Chrome Copper Seam Welding Wheels are forged, heat treated and offered as rough blanks or finished machined to your drawings. Forged and heat treated seam welding wheels improve production times and improve weld performance due to the fine grain structure that only forgings can offer. Forged seam welding wheels last longer and perform better. Home | Back | Contact us
