Abrasive Blast Media

A 100% recycled material that is an economically priced alternative to that of silica sand with 0% free silica. It is low dusting, sharp and angular while being lighter weight than many slags for increased consumption efficiency and production time (up to 30-50% less material used). It has very low particle embedment and will produce a whiter, cleaner finish. With a moderate friability (5.0 Mohs) Recyclability is low with 2-3 cycle passes. White or Brownish-mixed color in appearance.

Available in a X-Coarse, Coarse, Medium, Fine, X-fine grade. Packaged in 50 lb. bags (2,400 lbs/pallet), 3,000 lb bulk bags or supplied in bulk truckload quantities.

A lower cost, manufactured mineral, that will give you 2-3 cycles of reuse over that of slag. Staurolite or Starblast Ultra® is a hard mineral which will be ideal for new steel prep and general mill scale removal. Starblast® is a finer grade mineral that works great for light rust, brittle paint and mill scale. Both products will give you a more uniform blast pattern than slag and will be able to produce a white metal finish when blasted correctly. Both materials are manufactured by DuPont®. Brown to reddish-brown in color and <1%-3% free silica.

Packaged in 50 lb bags (4,000 lbs/pallet) or available in bulk quantities.

Garnet is an inert, non-toxic, naturally mined mineral that is a high performance, low-dusting abrasive alternative to slag media. It is fast-cutting and ideal for industrial coating applications, achieving a white metal blast without embedment or surface contamination. Garnet is also used for waterjet cutting applications. It is economical enough to be used as a single use abrasive or recycled for multiple uses. With a hardness of 7.5-8.0 on the Moh scale, it will break up less giving you more cycles of use (apx 4-7 cycles) while achieving the performance of more expensive recyclable abrasives. Garnet is more forgiving on equipment and parts wear than slag or other abrasives. Reddish-Brown to pink color in appearance.

Available in a variety of Sizes including Coarse (20/40), Medium-Coarse (30/60), Medium (60), Fine (80) or X-fine (120). Waterjet quality or Sandblast quality is available. Packaged in 55 lb bags (2,200 lbs/pallet), 2,200 lb or 4,400 lb bulk bags.

Aluminum Oxide is one of the most versatile abrasives available for surface preparation. It is a very hard and sharp, aggressive, high performance manufactured ceramic abrasive. It is a very cost effective abrasive when recycled, which is why it is the abrasive of choice when used in a blast room short of steel shot/grit. Less than 1% free silica, it has maximum resistance to breakdown, a low-iron content and eliminates the danger of rust-staining. You find aluminum oxide used in many applications and industries such as abrasive blasting, liquid honing, vibratory media, non-skid floor coatings, sandpaper, abrasive belt sanding and coated abrasive applications. Metal Finishing Supply only provides virgin grade, High-Quality, Factory certified and conforming Aluminum Oxide to its customers.

Brown Aluminum oxide is the most common type and used for general cleaning, finishing, deburring and etching of parts and surfaces. Due to its extreme hardness (9.0 Mohs), it has a low friability and can be recycled and reused many times, roughly 10-12 cycles. Brown in color, it comes and is stocked in a wide range of grit sizes ranging from 6 to 500 including micron sizes. Packaged in 50 lbs bags (2,000 lbs/pallet), 400 lb drums (1,600 lbs/pallet), or 3,000 lb bulk bags.

White Aluminum oxide is a "washed" aluminum oxide to effectively reduce the remaining iron and other metal contents and give it a "high-purity." It is suitable for sandblasting of non-ferrous metals (e.g. brass, aluminum), stainless steel, high alloyed steel and special alloys or special applications such as aircrafts, turbine or reactor construction. It is also used in medical and dental applications/industries or applications that require a sanitary use. Slightly longer life and lower toughness than its brown counterpart. White is available in grits 12 to 240 including micron sizes (and other special ordered sizes). Packaged in 55 lb. bags or 400 lb. drums.

Silicon Carbide is an extremely hard, aggressive abrasive used to clean and prep surfaces. It is usually used on super hard metals, ceramics, glass or stone. Silicon Carbide is designed to shatter upon impact to form a stream of sharp new cutting edges. Can also be used in lapping or slurry mix applications. Black or Green in color and Packaged in 50 lb. boxes or 300 lb drums.

Carbon Steel Grit is a manufactured cast abrasive from steel scrap that is angular and has extremely sharp edges. It is a very high performance abrasive used to clean, descale and prep metal surfaces including but not limited to railcars, structural steel, bridges and foundries. Due to its high recyclability, it is a superior choice abrasive for recovery. It can be put through over 100 cycles before the edges round off into a steel shot (ball) form. Because of this it is used in airblast rooms and airless wheel blast machines for surface preparation. Metal Finishing Supply only supplies Ervin Abrasive Amasteel material which meets the J-1993 and J-444 specifications for steel grit from the Society of Automotive Engineers and can be certified, upon order beyond those specifications for an additional charge.

Steel Grit is available in a wide range of sizes from G10-G120 and 3 different hardness ranges (M 47-56 HRC, L 54-61 and H 60 HRC). Packaged and stocked in 50 lb. bags (2,000 lb/pallet) or various weight 55 gal steel drums.

Stainless Steel Grit is recommended where ferrous contamination must be avoided such as aluminum castings and parts, stainless steel forgings, structural parts & welded fabrications, Zinc Pressure die-castings, forgings and corrosion-prone metal surfaces. It is a superior hardness and highly recyclable blasting media which exceeds the life of common abrasive materials by nearly 1,000 to 1 and that of steel grit by 2-3 times, providing apx 300 cycles of use. It is non-hazardous, contaminant-free and environmentally friendly and eliminates dust from abrasive fracture and breakdown.

Available is same sizes as carbon steel grit and packaged in 55 lb. plastic bags, 55-gallon steel drums or 2,200 lb. bulk bag

Glass Beads are a manufactured glass abrasive that is spherical in shape designed to clean, peen, finish and deburr. It will produce a “satin” or “shot-peened” finish with no profile and can be used on metal, plastic or rubber materials without contaminating the parts being finished. They will also provide a matte finishing on stainless. They can be recycled many times (apx 7-10 cycles) which make them an ideal product to be used in hand cabinets or blast rooms. Glass Beads are also used in Highway marking projects, epoxy projects and plating industries applications. Glass beads have 0% free silica, are low dust producing and are available in a wide variety of sizes from X-coarse to X-fine (10-400 mesh) including MILSPEC sizes. Clear to blueish-tint in color. Metal Finishing Supply is a Potters Industry distributor of USA made Ballotini® Glass beads (including Potter’s owned Flex-O-Lite and Cataphote brand impact abrasives)

Packaged in 50 lb bags (2,000 lbs/pallet) or 2,000 bulk bags
