Yellow color Aluminum oxide grain for abrasives
Yellow color Aluminum oxide grain for abrasives Description:
Yellow color Aluminum oxide grain for abrasives is coated with a layer of zirconium oxide. That makes the toughness and other physical indexes even better than ordinary iridium-coated aluminum oxide material.
After this treatment, the special iridium-coated aluminum oxide gets an excellent advantage in roughness, better ability to bond, better water affinity, and higher self-sharpening ability.
Zirconium-plated aluminum oxide is suitable for making abrasive tools. It makes the abrasive wheels with a longer lifetime and better sharpness. In the meantime, it could get a better polishing effect without burning scratches on the polishing surface.

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.
