Non-magnetic Cemented Carbide Balls Heat Stability High Polished Tungsten Steel Ball

Non-magnetic tungsten carbide balls have a series of excellent properties such as high hardness, good abrasion resistance, small coefficient of thermal expansion and good chemical stability, which are widely used in the manufacture of various moulds such as drawing moulds, cold forging moulds for fasteners, shaping moulds and so on.

With the improvement of manufacturing and application technology, Cemented Carbide is extended to be used in hot mining wells and sand wells. General cemented carbide ball due to ferromagnetism, in the magnetic powder forming process, easy to stick powder, resulting in hair pulling, seriously affecting the dimensional accuracy and surface quality of magnetic blanks, and thus should not be used for magnetic powder mould.

Due to the poor wear resistance of non-magnetic steel balls, the service life of moulds made of them is generally only a few tens of thousands of times. Non-magnetic tungsten carbide balls make it double, ten times or even hundreds of times the service life. Non-magnetic tungsten carbide balls have developed into one of the indispensable varieties of cemented carbide.
