High‑Performance Pre‑Alloyed Powder Improves Service Life & Processing Stability of Ceramic Grinding Wheels

In tile production lines, diamond ceramic edge‑grinding wheels operate under continuous grinding conditions. The service life of grinding wheels directly determines production‑line downtime frequency, production efficiency and overall manufacturing cost. As the core component of grinding wheel matrix, the quality and formula selection of pre-alloyed powder  for diamond tools are critical to ensure consistent long‑term grinding performance.

Conventionally mechanically mixed Alloy Powder suffers from component segregation, which causes uneven matrix microstructure, unstable hardness, weak retention of diamond grits and low sintering process tolerance. These drawbacks limit cutting efficiency and service life of ceramic grinding wheels. Sagwell self‑developedalloy powderadopts pre‑alloying technology. Metallic elements including Iron, copper, nickel and tin are homogeneously combined at atomic level during powder production, fundamentally eliminating segregation issues of mixed metal powder.

Kind2‑1318 Fe‑Ni alloy powder, one representative grade, reaches 2300 mesh, with recommended dosage of 20‑30% in ceramic grinding wheel formulas. Ultra‑fine pre‑alloyed powder SFN‑11 is also suitable for ceramic edge‑grinding wheels. This series of alloy powder for diamond tools stabilizes matrix hardness within 90‑105 HRB, balancing strength and toughness. Sintered density exceeds 98%, greatly enhancing mechanical retention force on diamond grits. Its broad sintering window ranges from 700℃ to 950℃, mitigating thermal damage to diamond particles and simplifying process control.

Practical industrial cases prove its performance. After replacing 20% ultra‑fine powder with Sagwell alloy powder, one customer extended grinding duration of ceramic wheels from 7 days to 10 days. Compared with elemental mixed powder under identical formula, SCF‑08 Fe‑Cu‑Sn pre‑alloyed powder boosts wheel sharpness and service life by over 30%.

Performance breakthrough of ceramic grinding wheels relies heavily on high uniformity and high density of matrix alloy materials. Specializing in R&D and manufacturing of premium pre-alloyed powder  for diamond tools, Sagwell delivers comprehensive technical support covering material selection, formula adjustment and sintering‑process optimization for ceramic‑wheel manufacturers. We help diamond‑tool products achieve longer service life and stable grinding performance to realize cost reduction and efficiency improvement for manufacturers。
