99.8% Al2O3 White fused alumina
Production Introduction of 99.8% Al2O3 White fused alumina
99.8% Al2O3 White fused alumina means white fused alumina with Na2O＜0.2%. The Na2O content will affect the hardness, temperature compressive strength and bending resistance strength, etc. With a special smelting process, HAIXU Abrasive presents Na2O < 0.2% and Na2O <0.1% WFA grain and powder which are suitable for high-level refractory and abrasive tools.

Product Feature of 99.8% purity White fused alumina
- The melting process is longer than ordinary white-fused alumina. The low Na2O white alumina gets a more fully crystallized crystal.
- Low Na2O content with max.0.2% and max.0.1%.
- Higher density than ordinary WFA. So it gets better refractory performance.
- Higher toughness. It is suitable for making high-quality abrasives wheels to increase lifetime.
Main Application of 99.8% Al2O3 White fused alumina
High-level abrasive wheels.
Lapping and micro lapping.
Abrasive blasting.
High-quality Refractory raw material.
Raw material for alumina sagger, ceramics, etc.
Shell molding paint additive to replace zircon powder.

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 Fixing furnace?
A: Our WFA grains F8-F220 are produced from a fixing furnace. 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.
