Fastblast No. 10
(BLASTITE BT)
Brown Fused Aluminum Oxide
Blastite BT (formally Fastblast No. 10) is a tough, medium density, virgin, fused brown aluminum oxide abrasive.
Blastite BT is designed for pressure blasting of materials of almost every type, including glass, granite, marble and ceramics. It is also used for the preparation of surfaces prior to painting or bonding; as well as for light deburring, scale removal and the generation of matte finishes. Blastite BT is closely sized, enabling operators to consistently duplicate finishes. Blastite BT is produced to conform to C.I.D.-A-A-59316, General Electric Aircraft Engine Group D50TF5 and most Pratt and Whitney Aircraft PMC specifications.
