[0002] Hard alloy powder is a kind of high-performance powder material, which is prepared by one or more metals or metal alloys through crushing, grading and other processes, and has the characteristics of high hardness, high wear resistance and high thermal strength. It is an important raw material for manufacturing hard alloy. After being pressed into shape, hard alloy powder can form hard alloy material with excellent performance after sintering treatment. It is widely used in mechanical processing, mining, oil and gas drilling, powder metallurgy, aerospace and other fields. Its excellent physical and chemical properties make hard alloy the first choice for many high-strength and high-wear applications.
