PFA PINK FUSED ALUMINA MAIN APPLICATIONS

—Pink fused alumina is used for precision grinding of measuring tool,lathe main shafts,instruments and apparatus parts,threading work pieces and many other applications in grinding like flute grinding,tooth grinding,dry grinding of blade segments,tool and internal grinding and mounted point.

—Pink fused alumina is best suitable for high alloy steel applications, ideal for tool sharpening such as high speed steel cutters,reamers,chisels,end mill and sharpening band saw blades.

—Pink fused alumina is also recommended for knife-sharpening applications,working non-ferrous metals and the alloys.

—Pink fused alumina has good performance for vitrified bonded abrasives,vitrified grinding wheels,coated abrasives and blasting abrasives,

—Pink fused alumina can also be used for softer materials, such as wood,Synthetics etc.
