Silicon Carbide Blast Media

Callus-remover blocks sold as effective blasting mediums are also great ways to remove calluses from skin surfaces quickly and precisely without producing too much heat; perfect for projects requiring extensive rust removal.

Hardened polypropylene plastic (HPP) stands near 9.5 on the Mohs scale and only trails diamond and boron carbide grit in terms of hardness. Furthermore, HPP is highly recyclable and cost-effective making it an economical solution.


Silicon carbide has an impressive Mohs hardness score of 9.1, making it one of the hardest abrasive materials available on the market today. Additionally, its chemical resistance and less propensity to oxidization make it ideal for general applications.

This blast media is perfect for removing paint and corrosion from steel and other hard materials. It works equally well when applied via suction- or direct pressure systems, and works equally well when used etching glass, sandblasting plastic and cleaning stone surfaces – including fiberglass without harming its surface surface.

Soft metals like titanium or any super metals wear out quickly when exposed to this media, rendering it ineffective for blasting them. But this media is dense and thermal conductivity is high enough that mirrors in astronomical telescopes often use it. Also referred to as carborundum; this hard chemical compound composed of silicon and carbon can be found naturally as rare gemstone moissanite.


Silicon carbide stands out as an ideal media for blasting applications requiring high precision and surface finish quality, such as those found in aerospace or automotive industries, where aluminum oxide may only be reused once due to its low Mohs hardness and force of impact on surfaces. As opposed to aluminum oxide which must be discarded after one use due to its low Mohs hardness and force with which it strikes surfaces, silicon carbide can be reused many times, making it the go-to choice when repeated blasting sessions require precision blasting applications such as aerospace or automotive industries where precision and surface finish quality must be top priorities such as aerospace or automotive industries.

Restoration industries rely heavily on these tools, as they enable the removal of paint and rust from a range of materials. Their sharp angularity and extreme hardness enable quick cleaning and preparation processes for multiple materials.

Silicon carbide is not only used for blasting applications; it is also an increasingly popular choice of coated abrasives used in wood sanding applications. Sanding wooden surfaces to prepare them for refinishing and coating. Due to its hardness and recyclability, silicon carbide also makes for ideal tools when used to create controlled etches in glass surfaces; an essential tool for artists looking to craft unique patterns on such materials surfaces.


Silicon Carbide Blasting Media offers hardness, speed, recyclability and versatility that is unparalleled, making it ideal for industries demanding precision surface finishes such as aerospace and automotive industries as well as restoration projects where removing paint, rust and contaminants is crucial to success. It is especially suitable for aerospace/automotive work as well as restoration projects where paint removal may be essential to complete restoration processes.

Blasting involves projecting high-velocity media through specialized machinery at high speeds, in order to strip an object, remove rust or prepare products for painting. There are various medias available; silicon carbide being one of the hardest and fastest blasting medias as well as useful for etching surfaces.

Electrical internal resistance furnaces use silica sand and petroleum coke to make this material, then molds it into an angular grain shape before breaking down continuously into sharp edges, producing an abrasive with an average hardness rating between 9-9.5 and an enduring crystal structure that can withstand extreme temperatures and voltages.


Cost estimates for blasting media vary based on the weight required to remove specific amounts of material from a surface, with grit typically costing less per pound than shot media. Silicon carbide hardness allows for shorter blast times and longer-lasting non-slip properties, leading to lower per hour costs than competing materials like aluminum oxide abrasives.

Silicon carbide features a low coefficient of friction and will not dissolve in most acids, making it ideal for use in various industries such as aerospace, automotive and restoration. Available in multiple forms – such as blasting grains and powders – silicon carbide is often utilized by these industries for various tasks.

Blast abrasives are classified according to their hardness, recyclability, and versatility – each factor playing an essential role in the success of any project.
