White fused alumina, WA, 38A, Fused Corundum, White corundum
abrasive
Product Description of White fused alumina:
White aluminum oxide has white color and a little higher hardness
and toughness comparing with the brown one. The grinding tools made
of this material are suitable for fine grinding of high carbon
steel, high-speed steel and stainless steel, Abrasive powder of
finer grit size, can also be used for precision casting and
high-grade refractory.
Benefits of CAEC White fused alumina:
1. We have the National Quality Supervision & Inspection Center For
Abrasives (NAQS), a national testing institution, which conducts
systematic inspection of raw materials, the whole process of
production and finished products to ensure the stability of product
quality.
2. As the chairman unit of China Abrasives Industry Association, we
have the most powerful resource integration ability of China
abrasives and abrasives, and maximize the cost control, so as to
achieve high quality and low price.
3. With a number of universities regularly transfer talents and
technology, with the strongest R & D strength and team, to ensure
that the technical formula has a leading edge.
