(1) High hardness, wear resistance and red hardness
The hardness of cemented carbide at room temperature can reach 86~93HRA, which is equivalent to 69~81HRC. It can maintain high hardness at 900~1000℃ and has excellent wear resistance. Compared with high-speed tool steel, the cutting speed can be 4 to 7 times higher, the service life is 5 to 80 times longer, and it can cut hard materials with a hardness up to 50HRC
(2) High strength and elastic modulus
The compressive strength of cemented carbide is as high as 6000MPa, and the elastic modulus is (4~7)×105MPa, both of which are higher than high-speed steel. However, its flexural strength is low, generally 1000~3000MPa.
(3) Good corrosion resistance and oxidation resistance
Generally, it has good resistance to atmospheric, acid, alkali and other corrosion, and is not easy to oxidize.
(4) Small linear expansion coefficient
When working, the shape and size are stable.
(5) The formed products will no longer be processed or reground.
Due to the high hardness and brittleness of cemented carbide, no cutting or regrinding is required after powder metallurgy forming and sintering. When special reprocessing is required, only electrical machining such as EDM, wire cutting, electrolytic grinding or special grinding wheels can be used. cut. Products of certain specifications usually made of cemented carbide are used on the cutter body or mold body by brazing, bonding or mechanical clamping.
