Description
Aluminum-Silicon (AlSi) Alloy Nanopowder / Nanoparticles (Al85Si15, APS: 50–100 nm, Purity: 99.9%)
Aluminum-Silicon (AlSi) Alloy Nanopowder (Al85Si15) is a high-purity (99.9%) nanomaterial with an average particle size of 50–100 nm, produced by the CVD (Chemical Vapor Deposition) method. This spherical, uniformly distributed nanopowder exhibits excellent dispersibility, low bulk density, good volume stability, high wear resistance, and superior thermal conductivity.
With its lightweight properties, low thermal expansion coefficient, and high corrosion resistance, Al-Si nanopowder is an essential material in advanced metallurgy, automotive, aerospace, and refractory applications.
