CuW75 · 75% Tungsten
W/Cu 75/25 Electrode Wheels
The workhorse alloy for seam-welding wheels
Tungsten 75% ±2%, balance copper · No MOQ · Lead time 10–14 days
Overview
Made by infiltration, finished by machining
Our W/Cu 75/25 electrode wheels are manufactured by copper infiltration of pressed tungsten skeletons, then finish-machined to your drawing — bore keyed, profiled, and balanced for smooth tracking at welding line speed.
The 75/25 composition delivers the arc-erosion resistance of tungsten with enough conductivity for continuous seam welding on galvanized and bare steels. Machined to OD tolerances of 0/+0.5 mm with 0.02 mm runout, every wheel runs true on your welding arm.
Material values shown are typical for the grade. Per-batch composition, density and hardness reports are provided on request — see quality control.
