Black Aluminum Oxide 240 mesh

Precision Surface Finishing with 240 Mesh Aluminum Oxide

This fine-grit black aluminum oxide is a fused alumina abrasive characterized by its extreme hardness (Mohs 9) and high density. The 240 mesh particle size is specifically designed for applications requiring a smooth, matte finish and minimal stock removal. It excels at removing light scale, surface oxides, and preparing substrates for coatings, bonding, or painting where a fine anchor profile is critical.

Unlike softer or rounder media, the sharp, blocky grains of black aluminum oxide continually fracture to expose new cutting edges. This self-sharpening characteristic ensures a consistent finish rate and reduces overall media consumption compared to single-use expendable abrasives. It is chemically inert and iron-free, preventing surface contamination on non-ferrous metals and stainless steel.

Key Industrial Applications

The 240 mesh grade is widely used across demanding industries. It is ideal for micro-blasting and precision work in aerospace and medical device manufacturing. In general manufacturing, it is used for cleaning molds, texturing rollers, and preparing surfaces for thermal spray coatings. It is also effective for etching glass and stone, and for lapping and fine finishing of hard metals.

Packaging and Supply Chain

We understand that uptime is critical. SPA2Z ensures this abrasive is available in ready-to-ship packaging options, including 25 kg bags for small-batch work, 50 kg bags for regular consumption, and 1-ton jumbo bags or bulk totes for high-volume blasting rooms and automated systems. Our supply chain is built to support both spot purchases and scheduled, bulk deliveries.
