White fused alumina P-Grit
Production of White Fused Alumina P-Grit
White fused aluminum oxide P-grit grain was made from high-quality alumina by melting above 2050 degrees in the electric arc furnace and cooling. As the most commonly used corundum in the abrasive industry, white fused aluminum has a long history in applications because of its high hardness, good self-sharpening advantages. Comparing white fused alumina F-grit grains, white fused alumina P-grit grain has more angular shape particles and better particle distributions. It is more suitable for coated abrasive tools.

Features of White fused alumina P-Grit:
White fused alumina P-grit abrasive material from HAIXU Abrasives is made from fixing furnace fused alumina blocks which are smelting by high purity aluminum oxide powder. White fused alumina P-Grit are produced by special milling equipment and technology. The WA P-Grit is of more consistent particle size. That will make grains easier to stick on the base of coated abrasives. It can be stuck firmly by bonder glue to a cloth or paper base. The advantages include high toughness, good particle distribution, shape grain size.

FAQ
Q: Are you a manufacturer or trading company?
A: We are a manufacturer of white fused alumina. HAIXU Abrasives has white aluminum oxide manufacturing experience of 22 years. We produce WFA section sand, WFA grains, WFA powder, etc.
Q: Are the WFA grains you get is produced from a Tilting furnace or a Fixing furnace?
A: Our WFA grains F8-F220 are produced from fixing furnaces. Fixing furnace WFA is of higher toughness and more durable.
Q: What is the content of Na2O of your WFA grains?
A: We have normal Sodium WFA grain and low Sodium WFA grain. Normal WFA grain Na2O content is max. 3% which is lower than most competitors. Low sodium WFA grain Na2O content is max.0.1%.
Q: Do you have a MOQ of WFA grain?
A: Generally no limit of MOQ. Even 25kgs(1 bag)is ok for us. But the logistic cost will be higher than normal.
Q: What substrate is the WFA grain blasting for?
A: WFA grain works well for Aluminum alloy, stainless steel, glass, acrylic, etc.
Q: What is the lead time of FCL WFA grain?
A: Generally 7-10 days after receiving the deposit.
