Conditioned medias are of a hardness on MOH’s scale 8
It should be noted that any abrasive described as 6 and over on the MOH scale is classed as abrasive
Cut Steel Wire pellets
Standard pellets are available in three types:
- High tensile carbon steel
- Medium tensile carbon steel
- Stainless steel
All are manufactured from a solid drawn wire producing a dense media, free from the commonly encountered casting defects and faults found in most cast steel abrasives.
The initial cylindrical shape of the wire pellet alters during use to produce a solid spherical particle slightly larger than that of its original diameter, it then retains its size and shape far longer than other commonly used abrasive media.
Both carbon and stainless steel pellets can be produced in a variety of size and hardness to G1, G2 and G3 levels of conditioning to suit individual customers’ needs and specifications.
G1 are cut wire pellets that have sharp edges and are ideal for applications that require a relatively deep surface etch to support a thick layer of a coating deposition to bond to.
G2 conditioned cut wire pellets have been subjected to a degree of rounding off to offer the product that will impart a less aggressive result.
G3 fully conditioned cut wire pellets have been pre worked so as to round them off, making this premium blast material for shot peening or stress relieving operations.
The more commonly used medias are:
- aluminium oxide
- white aluminium oxide
- urea and other plastic abrasives
- corn cob grit
- walnut shell grit
- glass beads
- crushed glass grit
- silicon carbide
- steel grit
- steel shot
- chilled iron grit
