At the end of last year, a wire saw customer mentioned to Sagwell's technicians that his product—wire saw beads—always had insufficient hardness and uneven sizes during cutting. When cutting mine rough stones or granite, the wire would break, and the beads would swing off-center. Through the unremitting efforts of Sagwell's R&D department, a wire saw alloy powder was born. As a formula powder, what properties make it worth having?
Let's first introduce this product: Wire Saw Alloy Powder SFN-11.
1. Large specific surface area and high activity, enabling better alloying with other elements during sintering.
2. Uniform particle size distribution, which is beneficial for customers' mixing and granulation processes.
B: Seven-element Pre-Alloyed Powder
As is known, compared with elemental mixed powder formulas, pre-alloyed powders can reduce the loss of elements like copper and tin at high temperatures during sintering. Meanwhile, since iron and cobalt are elements of the same group, the addition of cobalt in the original matrix formula can be appropriately reduced, saving costs.
C: Excellent physical properties
SFN-11 shows remarkable performance in density, flexural strength, and hardness between 700-850°C, outperforming some imported alloy powders. For hot-press sintering, it is recommended that the temperature does not exceed 880°C, as the diffusion of copper and tin accelerates at higher temperatures, leading to poor uniformity of the microstructure.
During the trial of this wire saw alloy powder, customers found that the hardness of the beads significantly increased, while the abrasion resistance remained almost the same as before. As a formula powder, Wire Saw Alloy Powder SFN-11 can be added at 100%, saving customers a lot of trouble.
