Product Description

Spherical cast tungsten carbide

 Spherical cast tungsten carbide which is dendritic crystal compose of WC and W2C and made by ultra high- temperature spheroidization or gas atomization process has a high melting point 2525 ^oC high hardness high flowability high wear resistance and chemical stability it is dark gray.

The products applied as the preparation of diamond drill bits matrixmaterials, plasma surfacing materials , coating materials and cemented carbide wear resistance rode wire materials. used in reingforcement of wear resistant surface and are used to make PDC drilling tools production by infiltration, spray welding ,overlay.
Spherical cast tungsten carbide powder is a new type of ultra wear-resistant ceramic particle material. Compared with traditional tungsten carbide, spherical cast tungsten carbide has two significant advantages. Firstly, it has a regular spherical appearance, good powder flowability, good wettability, and good adhesion with surrounding tissues after being added as particles, making it less prone to stress concentration; The second is that the internal structure of tungsten carbide particles is dense, with good toughness, small grains, high hardness, good wear resistance of the coating, and it is not easy to break and fail under load. Due to its excellent performance, spherical cast tungsten carbide powder is gradually replacing traditional tungsten carbide powder in surface protection of components such as mining machinery, petroleum machinery, construction industry, and foundries. It can significantly improve the wear resistance, corrosion resistance, and oxidation resistance of workpieces, and extend their service life.
