Bimetallic white iron wear parts are unique wear resistant materials in that they combine very high wear resistant qualities of a high white iron (ASTM A532 15/3CrMo, 700BHN-63HRC) with a weldable & high impact toughness mild steel through vacuum brazing to create a product that is exceptionally resistant to impact and abrasion while retaining.

We have Cast Toolings/Patterns to produce above 400 kinds of shapes and sizes.


Typical designs---the most common ones are:

◇ Chocky bars◇ Wear buttons & donuts◇ Standard wear bars◇ Wear plates
◇ Shaped wear bars◇ Skid bars◇ Wafer strips◇ Roll bars
◇ Grid bars◇ Knife edges◇ Shredder/Grinder hammer tips◇ Microlegdes
◇ Elbow wear blocks◇ Rockbox liners◇ Grizzly bars
