YDTech™ supplier of tungsten alloy spheres(samll or large)! OEM of miniature wolfram beads or tungsten carbide(WC,TiC) balls in china.

tungsten alloy spheres with better shock resistance than (Ni binder) this grade is typically used as a mining grade where toughness and abrasion resistance are also important. It has also proven useful in bearing applications.

tungsten carbide balls whit nickel binder had higher wear resistance and toughness make this an excellent general purpose grade for use in pumps and valves.

tungsten carbide balls are used where extreme hardness and wear resistance is required; in such applications as bearings, ball screws, valves, flowmeters. tungsten carbide balls are also used for coining and pivots, detents and tips for gages and tracers. decimal inch size tungsten carbide balls are widely used for ball izing or hole sizing. tungsten carbide balls are also used for gauging and checking.

tungsten carbide itself is practically insert; an attack is usually on the binder. since other materials are less expensive, the selection of tungsten carbide for corrosion resistance is usually not justified. In severely corrosive conditions, carbides with more resistant binders can be supplied for specific applications.

ball izing is a fast low-cost process to sizing and finishing tubing and holes in metal. pressing a slightly oversized tungsten carbide ball through the unfinished hole brings the hole up to desired size in seconds. The resulting surface finish is excellent and both size and finish results are very consistent. Industrial Tectonics can provide application assistance.
