FACTORY DIREST BLASTING MEDIA
BLASTITE® BT
BLASTITE® BT is a tough, medium density, virgin, fused brown aluminum oxide abrasive.BLASTITE® BT is designed for the pressure blasting of materials of almost every type, including glass, granite, marble and ceramic. 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.

NIAGARA BLAST®
• group graded virgin brown aluminum oxide
• used in blasting applications where size control is less critical DURALUM® SPECIALWHITE AluminumOxide
• more closely graded, high purity, white aluminum oxide
• composed of sharp, friable grains, specially treated for removal of iron
• premium material for use where surface contamination is unacceptable
• used in applications such as cleaning and deburring electrical circuit boards and medical components

CARBOREX® RA
• extremely hard, sharp silicon carbide grain that is more friable
than aluminum oxide
• used to blast extremely hard materials

TYPICAL BLASTITE® APPLICATIONS
• cleaning of investment castings
• scale removal in steam turbines
• surface preparation for thermal spray coatings
• rust removal
• hard oxide removal (titanium, zirconium, etc.)
• mill scale removal
• heat treat scale removal
• glass etching or frosting
• monument lettering
• aircraft engine overhaul
• matte finishing
• surface preparation
• durability (up to 20 passes)
• no free crystalline silica (unlike sand and many naturally occurring minerals)

GENERAL MEDIA INFORMATION
• Spherical Medias are used for peening and produce smoother surface finishes.
• Angular medias chip at a parts surface removing paint, rust, and scale quicker than round medias and produce a rougher surface finish and better anchor patterns for coating adhesions.
• Higher blast pressures reduce media life.
• Higher blast pressures increase production.
• Harder work pieces reduce media life.
• Dust collection keeps media clean.

When calculating media take into account:
• Media cost and life cycles
• Disposal fees (if blasting heavy metals use a very recyclable media)
• Production rate of media, labor and air compressor expense.
