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.
