Product Introduction

PM and casting process cobalt base alloy stellite 21 rod

Introduction

CoCrWalloy is a range of cobaltchromium alloys designed for wear resistance. 

It is a completely nonmagnetic and corrosionresistant cobalt alloy. 

There are a number of Stellite alloys, with various compositions 

optimised for different uses. Some are formulated to maximize combinations of wear resistance, corrosion resistance, or ability to withstand extreme temperatures.  

Features

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
