We all know that the main component of hard alloys is micro sized carbide powders of high hardness and refractory metals. Therefore, it is very solid, and many people are asking if the hard alloy used for the hard alloy ball teeth is metal? How did hard alloy come about? Below, the hard alloy strip manufacturer will explain to you the manufacturing method of hard alloy ball tooth hard alloy.
1. The manufacturing method of long strip hard alloy is as follows: first, the bonding alloy is made by high-energy ball grinding; Then, according to the prescribed weight ratio of hard alloy components, the mixture is added and subjected to strengthening ball milling. The hard alloy mixture produced by ball milling is then vacuum sintered into shape.
2. The hard alloys used for the long strip hard alloy ball teeth mainly include tungsten carbide (WC) and titanium carbide (TC). Hard alloys mainly include tungsten cobalt based (WC+Co) hard alloys (YG), tungsten titanium cobalt based (WC+TiC+Co) hard alloys (YT), tungsten tantalum cobalt based (WC+TaC+Co) hard alloys (YA), tungsten titanium tantalum cobalt based (WC+TiC+TaC+Co) hard alloys (YW).
3. A type of ultra-fine hard alloy ball tooth hard alloy and its manufacturing method. The alloy is a composite alloy composed of three main components: WC hard phase, Co Al as bonding metal phase, and rare earth metal element phase; The composition and weight content of the alloy are as follows: Co Al bonding metal phase: Al13-20%, Co80-87%; composite alloy: Co-AL 10-15%, Re1~3%，WC82~89%。 The manufacturing method is as follows: first, the bonding alloy Co Al is ground from high-energy balls; Then, according to the prescribed weight ratio of hard alloy components, the mixture is mixed and subjected to strengthened ball milling. The hard alloy mixture produced by ball milling is then vacuum sintered at a sintering temperature of 1360 ℃ and a holding time of 20 minutes. Extremely fine hard alloy is produced.
