Corundum is an aluminum oxide that can be found in nature as a mineral; in the industrial field is used synthetic corundum which is cheaper than the natural one and is obtained by the fusion of bauxite. 

It is a non-toxic abrasive, in fact it does not contain free silica and other components harmful to health, unlike other cheaper products that are used for sandblasting. 

The main feature of corundum is its high hardness (9 Mohs: only one point lower than diamond) which guarantees an exceptional abrasive capacity and the speed in obtaining the required result on any type of material. Having a high impact resistance, it is particularly

If you work in the blasting industry, you know that choosing the right material for your abrasive is crucial to achieving the desired result. Two of the most common materials used for making metal shot are steel and cast iron, but people are often unsure of the difference between the two. In this article, we will explore the differences between cast iron and steel and how these affect the choice of the right abrasive for your blasting process. 

Cast iron is an iron alloy with a significant amount of carbon, usually between 2.1% and 4.3%: thanks to this feature, cast iron is an extremely hard material, ideal for applications requiring strong abrasion such as blasting cast iron parts, cleaning boiler pipes, removing resistant paint, and much more.
