Tungsten Carbide Cobalt Sphere

Used in harsh environments and replace steel ball products. It can be used in high temperature environment above 400 °C, hard alloy hardness ≥90.5, density=14.9g/cm3.。

Scope of application:
Carbide balls are used in a wide range of applications, such as: ball screw, inertial navigation system, precision punching, precision bearings, instruments, pens, sprayers, pumps, mechanical parts, sealing valves, brakes pumps, punching holes, oil fields, hydrochloric acid laboratories, hardness measuring instruments, high-quality fishing gear, counterweights, finishing and other industries!

Production Process:
The production process of cemented carbide balls is similar to other carbide products:
Milling→recipe according to the application requirements→wet grinding→mixing→grinding→drying→sieving→post-forming agent→re-drying→make mixture→granulation→cold isostatic pressing→forming→sintering→ forming (blank, fine grinding) → packaging → storage.
According to the specific use requirements and related parameters, there are mainly hard alloy spherical products such as cemented carbide balls, tungsten steel balls, tungsten balls, and high specific gravity alloy balls. The smallest carbide ball can achieve a diameter of about 0.3.

Hard alloy balls with high hardness, wear resistance, corrosion resistance, bending resistance, commonly known as tungsten steel balls, refer to made of cemented carbide. Suitable for extremely harsh environments, extremely resistant to abrasion, impact, corrosion and deformation. The cemented carbide ball is based on a high hardness refractory metal carbide (WC, TiC) micron powder as main ingredient, with cobalt (Co) or nickel (Ni), molybdenum (Mo) as a binder,sintered into powder metallurgy products in a vacuum furnace or hydrogen reduction furnace.
