Product Description

Product Description:

Brown corundum is manufactured using high-quality bauxite as the raw material, coupled with anthracite and iron filings. The process of arc smelting is conducted at a temperature of 2000°C or higher, to ensure the product is of the highest quality. This results in a dense, hard texture, that is suitable for a variety of purposes.


The materials are then crushed and plasticized by a self-grinding machine, with a magnetisation process to remove the iron content, before finally being sieved into different sizes.These sizes of brown corundum are used in the manufacture of ceramic, high-resistance abrasive resin, and grinding, polishing, sandblasting and precision casting products. It is also a key ingredient in the manufacture of high-grade refractories.



High strength and durability: Brown corundum abrasive particles feature superior toughness and wear resistance, reducing the number of replacements needed and extending product lifetime.


High cutting rate: Brown corundum abrasive particles enable fast and efficient cutting, allowing for improved production speed and decreased costs.


No contamination: With their chemical inertness, Brown corundum abrasive particles do not contaminate the end-product while undergoing processing.


Chemical stability: Brown corundum abrasive grains possess a high degree of chemical stability, preventing them from reacting with other materials.


Excellent thermal shock resistance: Brown corundum abrasive particles are able to withstand large temperature variations, making them ideal for high-temperature applications.

Ceramic-bonded Abrasives

Brown corundum is used in ceramic-bonded abrasives, which are typically used in precision grinding and finishing applications. It is commonly used to create highly-finished surfaces, especially for intricate parts.


Resin-bonded Abrasives

Brown corundum is also used in resin-bonded abrasives, which are usually used during manufacturing operations such as cutting, grinding, and polish. They are ideal for many metalworking tasks.


Sharpening Stones

Brown corundum can be used in sharpening stones. These are typically used in the kitchen to sharpen knives and other utensils, which is an important step to maintaining their life.


Cladding Welding

Brown corundum is also commonly used for cladding welding. This welding technique is used to weld metal sheets and is utilized in various industries such as architecture and engineering.


Thermal Spraying

Brown corundum is used as a thermal spraying material to apply surface coatings. The thermal spraying method is capable of coating surfaces with a higher level of precision than other methods.
