Zirconia Fused Alumina

Product Description

Fused zirconia alumina is a high grade abrasives materials and fused corundum zirconium of bonded abrasive materials, fused zirconia alumina can application high grade refractory materials. It is high strength, high toughness, high temperature characteristics of Zirconia corundum, Fused zirconia alumina can manufacturer abrasive and High-performance heavy-duty sand wheels, also can application for Iron and steel industry, continuous casting and rolling, nozzle, flow channel, glass furnace refractories, etc. fused corundum zirconium can use of steel, cast iron, heat-resistant steel, titanium, nickel alloy, aluminum alloy, titanium alloys and other tungsten grinding. There are several names of fused corundum zirconium, such as Zirconium Oxide, Zirconia Aluminum Oxide (ZA), Fused Alumina ZA 25, zirconium corundum etc.
