Characteristics of white corundum
White corundum is crystallized by electrofusion refining, with high purity, good self-sharpening, acid and alkali corrosion resistance, high temperature resistance, and stable thermal properties. White corundum is slightly harder than brown corundum, slightly lower toughness, high purity, good self-sharpening, strong grinding ability, low heat generation, high efficiency, acid and alkali corrosion resistance, good thermal stability at high temperature.
Properties of brown corundum
In the process of application, it has the characteristics of no explosion, no pulverization and no cracking, especially its cost performance is much higher than traditional brown corundum, which makes it the aggregate and filler of brown corundum refractory materials.

Mohs hardness | 7.0-8.0 |
Density(g/cm3) | 3.6-4.2g/cm3 |
Bulk Weight (kg/m3) | 2400 |
Electric Conductivity | <250μs/cm(Offshore project requirements)<150μs/cm) |

Application areas
● Shipbuilding --- Stainless steel blasting, external blasting
● Marine engineering --- Stainless steel blasting, external blasting
● Oil/gas pipeline --- Carbon steel pipe, stainless steel pipe blasting
Garnet abrasives have been widely used in foreign countries. With the increasing number of foreign projects undertaken by domestic shipbuilding and offshore enterprises, garnet is also widely used in China along with the requirements and suggestions of foreign owners (shipowners), and the technical specifications of many projects even explicitly require the selection of garnet abrasives for stainless steel blasting and external blasting.
● The gradual improvement of domestic requirements for environmental protection and strict control of the use of quartz sand and copper slag also further make garnet abrasives have better market prospects.
