Basic Info.
Product Description
CoCrWalloy is a range of cobalt-chromium alloys designed for wear resistance.
It is an entirely nonmagnetic and corrosion-resistant cobalt alloy.
There are several cobalt alloys with various compositions
optimized for different uses. Some are formulated to maximize combinations of wear resistance, corrosion resistance, or ability to withstand extreme temperatures.
1. Heat Resistance, wear resistance, corrosion resistance
2. Made as required dimensions and materials
3. Main products: valve seat, pump parts, pistons, bushings, nozzles etc
