Glass Beads

Characteristics: Little abrasive, due to the spherical shape associated to the hardness and density of glass, they remove contaminations and finish surfaces, in the majority of cases, quickly and effectively, without destroying the tolerances of the treated parts. The material is inert, does not react with treated materials, as it does not encrust on the blasted surfaces. Its hardness is between 5 and 7 in the MOHS scale. 

Applications: Cleaning, satin finishing, engraving, deburring, shot peening (peening: generates high micro-tensions which alter the normal characteristics such as resistance to fatigue, to friction, to cracks, to wear, to oxidation and to high temperatures, among the most important ones). Low productivity, medium recycling.
