INTRODUCTION:
Product Description

White Fused Alumina

Our WFA grains are produced from high purity calcined or feedstock alumina in electric arc-furnaces. the molten material undergoes cooling, crushing, grinding, sieving, classifying and, of course, various quality checking procedure before it is packed for delivery. 

White Fused Alumina product uses

White Fused Alumina is widely used in the refractory industry as it is a very pure low iron alumina suitable for a range of applications.  Specific refractory applications include high tech refractory castables, isostatic pressed refractories and pre-cast refractory shapes. the benefits of White Fused Alumina in these applications are that it has a very high alumina content, low impurities and stability at high temperatures.
