Product name	Tungsten carbide balls
Series	YG6 YG8 YN6 YN8
Feature	Large hard Tungsten Carbide ball has high hardness, wear resistance, corrosion resistance, bending resistance, and bad use environment, and can replace all steel ball products. Carbide ball hardness ≥ 90.5, density = 14.9g/cm3.
Density	14.9g/cm3
Product process line	The production process of cemented carbide ball is similar to that of other cemented carbide products, mainly including powder preparation → recipe according to application → wet grinding → mixing → crushing → drying → sieving → adding molding agent → drying → sieving Prepared mix → granulation → cold isostatic pressing → forming → sintering → forming (blank) →grinding → packaging → storage. According to the specific application requirements and related parameters, there are carbide alloy ball, tungsten steel ball, tungsten ball, high-density alloy ball and other carbide ball products. The smallest carbide ball can do about 0.3 in diameter.
