white fused alumina/corundum powder w10 w7 w5 w3.5 alumina powder

WA

Corundum powder/White Fused Alumina/WA

Specification of alumina powder:

High purity and low sodium white fused alumina is high purity α-type alumina powder containing no less than 99.7% AL2O3. This product is developed to maintain a low NA2O amount, as low as 0.15% or less, so it has an excellentinsulation capacity. It can be used as insulation coating material for a heater of electronics tubes and various insulating film materials.

It is the essential material for making ceramic filler, insulator coating, thermally conductive interface materials, gap pad electrically insulating and noninsulating gap fillers, thermally conductive adhesive tapes and thermal clad insulated metal substrates for conducting heat.

It is widely used in high standard finishing, grinding and polishing industries.
