White Fused Alumina(WFA),also called White Fused Aluminum Oxide, named by its white color, belongs to the electro fused artificial corundum group. It’s an important mineral with chemical and high temperature stability, great purity, hardness and fireproof and refractory characters. White fused alumina is one of the most widely used raw materials for so many industrial fields, including refractory, bonded abrasives and coated abrasives industries.
We are professional manufacturer for customers in different industries and countries according to FEPA, JIS, GB, ISO standard. 0-1mm, 1-3, 3-5mm etc. for refractoriness, FEPA F sizes for bonded abrasives aluminum oxide tools, FEPA P sizes for coated abrasives aluminum oxide products.
Gunning materials are high temperature refractory materials which are placed using varying types of Gunning equipment through a nozzle with additions of Water and Air. These materials are designed so as to stick in place and set quickly when being applied to the required area such as walls and roofs.

▼Payment:
1).Our first choice is T/T. For a large order 40% T/T in advance is earnest money, the rest to be paid in 7-10 days after getting B/L copy. For a small order,100% T/T in advance.
2).Second choice is L/C. We can accept irrevocable L/C at sight. For a large order 40%T/T, 60%L/C. We couldn’t accept L/C for a small order. The best way of payment we advise is T/T, because L/C is very complicated and a lot of extra fee to give the bank.
3).The others: West Union, Paypal.
