Metabrasive Chilled Iron Grit (“Metablast”) is a high performance, fast cleaning
hematite cast iron abrasive. It is an induction furnace melted chilled iron abrasive
and its low residual elements, together with a tightly controlled chemical analysis
ensures an extended service life.
Although used in wheel blasting machines, Metablast is used primarily in Airblast
applications. In both laboratory and production conditions, Metablast's performance
is exceptional with many users having discovered the following in-service benefits:
Controlled etch
Required surface finish
Rapid cleaning rate
Lower levels of dust contamination
Greater visibility for the operator
Extended abrasive life, often 35% higher than conventional chilled iron grit
Lowest overall blasting cost.
Metablast is made in accordance with ISO 11124-2 : 1993, (BS7079: Part E2 : 1994).
Size ranges vary from G05, nominal size 0.005” (0.125 mm), to G80, nominal size 0.080”
(2.0 mm).
Metablast is also available in round particle form. Although not suitable for blast
cleaning, it is widely used for ballast, innoculation and as an aggregate in high
density concrete.
