Spherical Buttons Tungsten Carbide Inserts Stable Chemical Properties
Spherical Carbide Buttons: Precision Tools for Superior Performance
Introducing our high-quality carbide spherical buttons, meticulously crafted to elevate drilling and excavation operations to new levels of efficiency and effectiveness.
These precision-engineered tools are designed to withstand the toughest conditions while delivering exceptional performance in various applications.
Cemented carbide is a kind of composite material which is made of refractory metal hard compounds (WC, TiC, etc.) and bonding metals (CO, Ni, Fe, etc.) by powder metallurgy. Cemented carbide has high hardness, high wear resistance, high strength, high modulus of elasticity, low coefficient of thermal expansion, high red hardness and stable chemical properties.
