AztroGrit Aluminum Oxide Powder - 5 microns (avg size); 250 gm

Turned the silver totally black

Is what it says it is. Oxide aluminum wasnt what I needed. Plain aluminum powder is what I wanted

Much aluminum Such powder

Much aluminum Such powder

Carry a small bottle of this to use on my strop to keep my wood carving knives sharp. This is a great product and keeps my knives very sharp. Much cheaper to buy it this way than buying the over priced little 1 oz jars from wood carving supply shops. Will last a very long time.

I bought this expecting aluminum powder. My mistake, not the seller. It is aluminum oxide powder as described. No right for cold casting.
