Iron-Copper-Tin Alloy Powder: High-Performance Pre-Alloyed Powder for Diamond Small Saw Blades
2026-08-03
In stone and concrete processing industries, the quality of Alloy Powder for diamond small saw bladesdetermines the performance, stability and service life of cutting tools. Traditional mechanically mixed single Metal Powders have obvious defects, including poor fluidity, chipped green compacts, component segregation and brittle matrix, which fail to meet mass production standards of high-precision small saw blades. Nowadays,pre-alloyed powder has become a mainstream matrix material, and iron-copper-tin alloy powder stands out for its wide process compatibility and cost-effective performance.
-
High-quality iron-copper-tin pre-alloyed powder adopts ultra-fine powder technology. Compared with conventional raw powder, it delivers superior fluidity and filling performance, realizing high cold-pressed density and high blank strength. It effectively avoids edge chipping and cracking of thin saw segments, greatly reducing product rejection rate.

This powder features excellent sintering activity with an optimal sintering temperature of 880-920℃, supporting both hot pressing (2-7MPa) and pressure-free sintering. After hot pressing, the matrix hardness reaches 85-95HRB, while pressure-free sintering achieves hardness over 90HRB and density above 90%, fully adapting to hard stone cutting scenarios. It optimizes the brittleness defect of traditional iron-based matrix, significantly enhancing tooth bending strength and eliminating tooth breakage risks during high-speed operation.
-
Capable of 100% single addition, the formula-simplified pre-alloyed powder avoids segregation caused by multi-powder blending. Its strong diamond retention allows lower diamond concentration, while low-temperature sintering reduces graphite consumption. In actual production, it helps manufacturers cut comprehensive costs by more than 15%.
