Sub-WA

High Pure Brown Fused Alumina This kind of product developed bases on Brown Fused Alumina, Its chemical and physical specification are close to white fused alumina, so we name it as Sub-White Fused Alumina. With the prefect crystal, similar hardness like WA, and good toughness like BFA, the product has been wildly used to substitute White fused alumina, it is a very good refractory material.
