Product Feature of 99.8% purity White fused alumina

  1. The melting process is longer than ordinary white-fused alumina. The low Na2O white alumina gets a more fully crystallized crystal.
  2. Low Na2O content with max.0.2% and max.0.1%.
  3. Higher density than ordinary WFA. So it gets better refractory performance.
  4. 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.
