Présentation du produit du granule d’alumine fondue blanche standard FEPA F16
Le granulé d’alumine fondue blanche standard FEPA F16 est l’un des matériaux abrasifs les plus couramment utilisés pour les outils abrasifs. Le grain F d’alumine fondue blanche peut être utilisé pour les abrasifs liés tels que les meules de coupe, les meules, les meules vitrifiées, les pierres à aiguiser, etc. L’alumine fondue blanche est fabriquée par un procédé de fusion à haute température de l’oxyde d’aluminium dans un four de fixation. Il possède une excellente propriété d’auto-affûtage, une bonne ténacité et une capacité de meulage agressive.

FAQ
Q: Are you a manufacturer or trading company?
A: We are a manufacturer of white fused alumina. HAIXU Abrasives has white fused alumina manufacturing experience of 22 years. We produce WFA section sand, WFA grains, WFA powder, etc.
Q: Are the White fused alumina grains you get is produced from a Tilting furnace or a Fixing furnace?
A: Our White fused alumina grains F8-F220 are produced from fixing furnaces. Fixing furnace White fused alumina is of higher toughness and more durable.
Q: What is the content of Na2O of your white fused alumina 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:How do you make quality control on White fused alumina before delivery?
A: We will check the quality of white fused alumina including: chemical content, particle size distribution, milling toughness of white fused alumina, Bulk density of white fused alumina, whiteness of white fused alumina, etc.
Q: What is the lead time of FCL White fused alumina?
A: Generally 7-10 days after receiving the deposit.
