Product Description

8mm 8.5mm High-Density Tungsten Carbide Ball Hard Alloy Tungsten Steel Ball
 

 

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.
 

Features:

 

Superior wear resistance

 

High hardness and mechanical strength
 

Good corrosion resistance
 

High precision for tolerance

 

They're widely used in oil&gas, bearings, ball screws,valves and flow meters.pen,

 

spraying machines,pump,machinery parts and other industries.

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.

 
 

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.
