Most conventional saw blade matrices use a 70% copper-iron composition. However, microscopic structural gaps between common iron powder and Sagwell ultrafine iron powder deliver vastly different blade performance and operational stability.
Common iron powder has irregular particle morphology and uneven grading. During pressing and sintering, these inherent flaws cause poor matrix compactness and ingredient segregation. Many manufacturers using 400-500 mesh ordinary powder struggle with weak diamond bonding. This easily triggers grain shedding and pit defects, resulting in fluctuating cutting quality and early tool scrapping.
Sagwell ultra-fine iron powder solves these pain points with precise particle control and uniform microstructure. Its developed dendritic grains provide excellent cold-press formability, ideal for heavy-duty mining saw cutter heads. Sintered matrix compactness exceeds 98%, with flexural strength hitting 950MPa. Practical industrial verification proves that Sagwell powder improves cutting sharpness by 15%, stabilizes product quality, and reduces formula nickel consumption by 8%.
The powder features high sintering activity and fully sinters at 700-800°C, avoiding diamond thermal damage and preserving consistent cutting capability. With two decades of specialization in ultrafine iron powder R&D and manufacturing, Sagwell delivers reliable material and technical support, empowering manufacturers to produce durable, high-efficiency mining saw blades.
