Sandblasting Media & Abrasives — Professional Grade
Choose the right blasting media for your project from Le Lematec's professional-grade abrasive lineup. The media you select determines your surface finish, removal speed, and substrate safety. Our brown corundum (aluminum oxide) and silicon carbide media are available in optimized grit sizes for the most common sandblasting applications — from aggressive rust removal to fine surface finishing.
Media Selection Guide
Brown Corundum (Aluminum Oxide, 220 Grit) is the most versatile general-purpose media. It aggressively removes rust, paint, and mill scale while being reusable for 5-8 cycles. Ideal for steel and iron surfaces where you want a clean, profiled surface ready for coating.
Silicon Carbide (100 Grit) is the hardest commonly available blasting media. It cuts faster than aluminum oxide and produces a finer surface profile. Best for hard metals, ceramics, and applications requiring aggressive stock removal with a smooth finish.
Frequently Asked Questions
Q: How many times can I reuse blasting media?
A: Brown corundum (aluminum oxide) can typically be reused 5-8 times before the particles break down too small to be effective. Silicon carbide lasts 3-5 cycles. Screen or sift media between uses to remove fines and debris that reduce efficiency.
Q: Which media is safe for aluminum surfaces?
A: For aluminum, avoid iron-based media (steel grit/shot) which can embed iron particles causing galvanic corrosion. Safe options include glass beads, walnut shell, plastic media, and soda. Silicon carbide works but use lower pressure (40-60 PSI) to avoid excessive material removal.
