Multi-component pre-alloyed powder with excellent metallurgical bonding properties serves as an effective material solution to improve the high-temperature adaptability of diamond tools.
Diamond tools such as grinding discs and segments are commonly used in floor renovation, stone finishing and refractory machining. During operation, high-speed friction generates intense heat, placing these tools under sustained high-temperature stress. Insufficient thermal stability of the tool matrix easily causes diamond graphitization, weakening cutting performance and shortening tool service life.
Sagwell’s self-developed pre-alloyed powder integrates iron, copper, cobalt and nickel elements at the atomic level to form a stable solid solution structure with outstanding high-temperature resistance. Compared with conventional mechanically mixed powder, the tool matrix made from Sagwell alloy powder maintains stable hardness and oxidation resistance above 500℃, effectively shielding diamond grains from thermal erosion and structural damage.
In continuous dry grinding of concrete and granite, tools equipped with Sagwell alloy powder deliver slow matrix oxidation and stable diamond exposure height. This prevents tool clogging and premature diamond shedding resulting from matrix softening. The uniform alloy structure significantly enhances thermal fatigue resistance under temperature cycling and restrains microcrack growth.
The improved performance cuts tool replacement frequency and raises single-batch operating area by over 30%, perfectly suitable for large-scale floor projects and continuous production lines. Sagwell’s high-performance pre-alloyed powder enable diamond tools to maintain stable, efficient operation in harsh high-temperature working conditions.
