G25 Tungsten Carbide Machinery Bearing Balls For Radio 4.76MM 9.525MM 3.56MM
Cemented Tungsten Carbide is an incredible material. It was originally developed for use as a cutting tool in machine tool applications where it still finds wide use today. It is extremely hard at 91 HRA which is equivalent to 1500 Vickers 30.
This material is very wear resistant, with some abrasion tests showing it at 30 times hard steel. It has good long-term dimensional stability which makes a good material for gage applications.
Applications
