Product Name: Carbide milling balls
Grade: YG8, YG6, YG15
Material: tungsten carbide, hard alloy
Surface: sintered, finished.
Typical sizes available: 0.3mm-100mm
Description:
High hardness and dimensional stability make tungsten carbide balls the preferred choice for precision spherical valve, gauging and checking instruments, and meters, ball bearing, flow meters, inear bearing, re-circulating ball screws, liner, bearings, etc.
Hard alloy ball is widely used for applications requiring extremely hardness and resistance to wear and abrasion, hard impacts and shocks. Usually, tungsten carbide is about three times harder than steel.
