Reade Advanced Materials offers:
Emery Abrasive Powder
Emery Abrasive Powder Synonyms:
Iron spinel, hercynite, aluminum oxide, aluminum trioxide, corundum, impure corundum, natural aluminum oxide
Emery Abrasive Powder Designations:
Chemical Formula: Al2O3 + an iron bearing mineral + trace impurities such as mullite, titania, silica, and magnesia
Emery Abrasive Powder Description:
A natural occurring odorless mineral having its broadest use as an abrasive in polishing applications. An intimate mix of corundum and magnetite. The higher amounts of impurities and weaker internal structure than naturally occurring minerals has restricted its growth in new applications.
Al2O3= 58.0%, Fe2O3= 24.0%, SiO2= 4.0%, TiO2= 3.0%, CaO= 2.0%
- Aggregate Sizes Available: 3/8" x F, 1/4" x F, 8/16 grit, 8/35 grit, 12/30 grit, 14/36 grit, 24/60 grit, 30/40 grit, 30/80 grit, and 100/200 grit
- Grain Sizes Available: 72, 80, 92, 100, 120, 150, 152, 180, 200, 220, and 240
