Product Details
Black aluminum oxide for sandblasting replace Al2O3 85% BFA stable supply
Black aluminum oxide is obtained from the fusion of high iron bauxite or high alumina bauxite in electric arc furnace. Its main component is α-Al2O3, with Al2O3 62%. With moderate hardness, Lower hardness than Brown aluminum oxide, strong tenacity, low grinding heat and less prone to surface burning, is an excellent alternative abrasive.
Commodity: Black Fused Alumina
Production Type: Tilting Furnace, Rolling crushing or Barmac Crushing

Sandblasting, ideal choice to replace 85% Al2O3 BFA
Black Aluminum Oxide girts can be used as blasting media to sandblast for Stainless steel, metal products, optical glass, bamboo and wood products for impurity cleaning, vessel body de-rusting cleaning, de-burring, surface decontamination , matte treatment, pre-treatment before coating, pipeline cleaning, Jean cloth sandblasting, etching art, stress relief etc.
Comparing with Grade A Brown Aluminum oxide (Al2O3 95%), and Grade B Brown Aluminum oxide (Al2O3 85%), Black aluminum oxide is with moderate hardness, high toughness and stable performance, can replace 85 BFA easily, and has stable supply and lower price.
Take 12# for example:
Performance Abrasive | 95% BFA 12# | 85% BFA 12# | 62% BA 10# |
| Al2O3 | 95%min. | 85%min. | 62% min. |
| Hardness | 2100-2300HV | 2000-2150HV | 2000-2100 HV |
| Crushing Type | Barmac | Rolling | Barmac+Rolling |
| Bulk Density | 1.94-1.99g/cm3 | 1.80-1.88g/cm3 | 1.48-1.52g/cm3 |
| Cleanness | Good. No exact test data each batch. Can see it very clean by eyes easily | Not so good as BFA 95% and BA 60% | Good. Can see the cleaness by eye easily |
| Quality Stability | Premium Products Stable Quality Regular test | Off-grade products Raw materials from different source, test each batch | Premium Products Stable Quality, test every day. Samples and test reports each batch keeps for 2 years |
| Supply Capability | OK. Sometimes a little short supply, depending on the government policy | OK. Often short supply limit by government policy | Priority supply 1. YEDA is the biggest BA suppier in China. Supplying to Saint-gobain worldwide. 2 factories, one in Xinmi, Zhengzhou, another in Linfen, Shanxi. Annual output of BA grits 30000mt. From Linfen is15000mt. |
