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.

 

Tungsten carbide balls provide a binder percentage slightly higher than the standard balls (7-9%).
 
They are available on demand.
 
The mechanical properties and corrosion resistance are a little lower if compared to standard K20 balls.
 
Virgin powder is strictly used into this kind of production.
 
 
Applications
Special and hydraulic precision valves, special bearings, couplers, flow meters, sprayers, recirculating balls, ball spindles, tooling machines, sliding rails, ballpoint pens, pin and tips for indicators, precision measurement instruments, medical instruments. They are used in naval, mining, petrol and coining industry.

Corrosion Resistance
As a general rule Tungsten Carbides with Cobalt binder show good corrosion resistance into basic solution while they are not resisting into acid solutions.
