Brief Introduction of Pre-alloyed Powder
Pre-alloyed powder can be selected for the production of diamond cutter (segment). The pre-alloyed powder is uniformly mixed, which has low oxygen content, good holding power to diamond, and stable overall performance. In addition, the pre-alloyed powder has low loss of low-melting metal during the sintering process. A temperature difference of about ten degrees has no effect. For ordinary diamond bits, iron-copper pre-alloy powder can be selected. If you want to improve the sharpness, you can choose iron-copper-tin pre-alloyed powder. If the hardness is better, you can choose iron-copper-nickel pre-alloyed metal powder. You can choose alloy powder according to your own formula and cost control.
The pre-alloyed powder is more evenly distributed than the mechanically mixed powder, which fundamentally avoids component segregation, makes the carcass structure uniform and the performance tends to be consistent; the pre alloyed powder is fully alloyed, so that the carcass has high hardness and high impact strength, which can greatly Improve the compressive and bending strength of sintered products, increase the holding power of diamonds, increase the sharpness of diamond tools, and extend the service life of the tools. The composition of each element of the pre alloyed powder is fixed, which fundamentally avoids the occurrence of various problems in the compounding process, and provides conditions for the stability of product quality. Pre-alloying greatly reduces the activation energy required for the diffusion of metal atoms during the sintering process. The sintering performance is good, the sintering temperature is low, and the sintering time is shortened. Electricity consumption; in the case of the same cutting performance, the use of pre alloyed powder can reduce the diamond concentration by 15%-20%, significantly reducing the cost of diamond tools.
