Product introduction

Cemented carbide particles, also known as crushed cemented carbide particles, are made from sintered tungsten carbide material, with an optimized and carefully controlled cobalt content ranging from 5% to 12%. This ensures the particles’ wear resistance as well as their strong bonding to the metallic matrix. The nickel-copper alloy matrix contains between 30% and 35% copper, boasting a density of 14.8 g/cm³ and providing a robust support base with a tensile strength of 690 MPa. Additionally, a special flux coating can minimize oxidation reactions during the layer-welding process, ensuring a uniform and orderly distribution of the alloy particles.

The cemented carbide particle product is primarily used for repairing worn parts in industries such as oil drilling, mining machinery, and construction, making it particularly suitable for overlay welding of wear-resistant layers on tools like twist drills, milling shoes, and wear shoes. The overlay welding process employs an oxyacetylene flame, requiring the use of a neutral or slightly carburizing flame for preheating; after welding, slow cooling must be carried out to ensure weld quality.
