Extra High-Temperature Easy-Machine Glass-Mica Ceramic Sheets and Bars

Also known as Macor, this glass-mica ceramic withstands temperatures up to 1470° F. You can machine complicated shapes and precision parts from it in a fraction of the time it would take using other types of fired ceramic. Its good electrical and thermal resistance make it a common choice for heating and soldering fixtures.

Abrasive Blasting Media

Remove paint, coatings, and rust or add texture to surfaces. This media is suitable for use on a wide variety of surface materials.

Our abrasive blasting materials are sorted from least to most aggressive. The more aggressive the media, the more material it removes from your surface.

Both particle mesh size and grit measure the size of the abrasive particles. The higher the number, the finer the particles are.

Glass/Aluminum Oxide Grit

A mixture of glass bead and aluminum oxide grit, this media is less aggressive than pure aluminum oxide grit. It’s tough enough to clear away corrosion but gentle enough to etch aluminum and plastic without gouging them.

Low Reusability—Effective for a handful of cycles under normal blasting conditions.
