Different metals respond uniquely to various abrasive materials. What works perfectly for steel might damage delicate aluminum or leave copper with an uneven finish. Understanding the nuances of choosing the right sandblasting grit for different metals saves you time, money, and frustration.
Aluminum
Glass beads work exceptionally well for this metal, providing smooth surface preparation without causing gouging or warping. The fine texture of glass beads removes oxidation and old coatings while preserving the metal’s integrity.
Plastic media offers another excellent option for aluminum surfaces. This abrasive removes paint and corrosion without generating excessive heat, which can warp thin aluminum pieces. You’ll achieve consistent results across complex shapes and delicate components.
Steel
This metal responds well to more aggressive abrasives due to its durability and hardness. Steel grit delivers outstanding results for heavy-duty preparation, effectively removing rust, scale, and stubborn coatings. This abrasive creates an excellent anchor pattern for subsequent coatings.
Aluminum oxide provides versatility for steel applications. It cuts through surface contaminants efficiently while offering good recyclability. The angular particles create ideal surface roughness for paint adhesion and long-lasting finishes.
Cast Iron
Steel shot works effectively for this application, providing controlled impact that removes scale and rust without causing fractures. The spherical shape delivers consistent results across irregular surfaces.
Aluminum oxide offers another suitable choice for cast iron, particularly when you need to remove heavy corrosion or old coatings. The angular particles cut through tough deposits while the moderate hardness prevents damage to the base metal.
Brass
Glass beads provide ideal results for brass surfaces, removing tarnish and oxidation while preserving the metal’s natural beauty. The gentle action prevents distortion of intricate details and thin sections.
Corn cob media works well for lighter cleaning applications on brass. This organic abrasive removes surface contaminants without altering the metal’s dimensions or finish quality.
Copper
Walnut shell media excels for copper applications, removing oxidation and stains while preserving the metal’s natural color and texture. The organic material breaks down during use, preventing over-aggressive cleaning.
Baking soda blasting offers another excellent option for copper restoration. This mild abrasive removes corrosion and old coatings without damaging the underlying metal structure.
