What Aluminum oxide blasting grit to use for Coatings/Corrosion Removal 

If you’re wanting to remove coatings and corrosion from surfaces, abrasive blasting is a great method to use. 

Abrasive blasting makes use of an air compressor to propel blast abrasive grains through a nozzle at high velocity onto your chosen project surface. It has various applications, such as treating aluminum wheels.

Before you start a blasting project, it’s important to consider the grit size. When you want to penetrate thick layers of paint and rust, it’s best to go for a small grit size, which means the particles are very coarse and rough . The grit size has an inverse relationship with the particle size. For example, if you have a blasting media that has a grit number around 220, then the particles are very fine. This is best used when you don’t want to damage your surfaces. 

Aluminum oxide is a popular blast media for coating and corrosion removal, but there’s an even better option that’s both cost-effective and powerful. The answer is superoxalloy.

The Best Method

10X Engineered Materials has created a line of superoxalloy abrasives that will get the job done and leave your surfaces smooth, clean, and ready to recoat.  Products include KinetiX (high-production grades) and EpiX (precision grades). 

These abrasives are made up of polymorphous particles, meaning they can perform multiple functions at one time, removing the layers quicker and more efficiently in just one step. Additionally, these abrasives are strong but gentle and will leave the underlying surface unharmed.

When wanting to remove mill scale, using a bag of KinetiX with a grit size of 20/70 or 40/70 is best. 

Currently, KinetiX and EpiX are available from abrasive distributors around the US. If you don’t see a distributor near you, contact 10X and we will work with you to get you what you need. EpiX abrasive, which is best for precision applications such as powder coating and medical applications, is also available to purchase directly from the 10X Engineered Materials website.
