The 100-grit size provides a balance between material removal efficiency and surface finish quality. Like other aluminum oxide media, it maintains a Mohs hardness of 9 for robust cleaning and etching on steel, stainless steel, and other metals, as well as glass etching when desired.
Key Features
- Balanced grit for broad applications
- Wet/dry compatibility
- High hardness for effective blasting
Buying Guide: Media Type, Grit, and Use Case
Media selection depends on substrate, desired finish, and equipment. Aluminum oxide offers high hardness and longevity, ideal for metals and coatings prep. Fine grits (like #120) excel for precise coating removal and glass etching, while coarser grits process heavy rust or mill scale more aggressively. Glass beads provide a smoother, peening-like finish and are suitable for softer metals and decorative prep when a gentler touch is needed.
Key considerations include hardness (Mohs scale), contamination risk (avoid crystalline silica), and reuse life. Wet blasting can reduce dust and heat, but requires compatible media and equipment. For large jobs, opt for bigger bags to minimize replacement frequency. If you work with multiple materials (steel, stainless steel, aluminum), choose media certified for non-reactivity with coatings to preserve integrity.
Performance varies by equipment and nozzle size. Thicker parts or paint layers may benefit from coarser media first, followed by finer media for finish refinement. Always consult equipment manufacturer guidelines regarding compatible media types, flow rates, and recovery systems to maximize efficiency and minimize wear.
Overall, the media selections covered here provide a spectrum of hardness, price, and reuse potential. For metal fabrication shops, combining a coarse, durable option with a finer finishing grade often yields the best balance of cleaning power and surface quality.
