Product Description

Product Description:


The purity of brown corundum abrasive is unparalleled, with its good crystallization, strong fluidity, low coefficient of linear expansion, and unrivaled resistance to corrosion. Countless fire-proof production companies have put this product to the test, and their results have only served to confirm its reliability and durability in various applications.


Unlike traditional brown corundum, this refined version is free from explosion, chalking, and cracking throughout its use, making it an outstanding choice for fused alumina refractories. Its cost-effectiveness is unbeatable, making it the premier aggregate and filler for various industrial applications.




High Chemical Stability

In addition to its impressive hardness, brown corundum also boasts high chemical stability and corrosion resistance. It is able to withstand harsh environments, such as exposure to acids, alkalis, and high temperatures, without deteriorating or corroding.


High Density

With a density of 3.90g/cm3, brown corundum has a relatively high density compared to other materials. This density contributes to its overall strength and durability, making it a popular choice for use in heavy-duty applications.


Small Coefficient of Thermal Expansion

One of the most unique properties of brown corundum is its small coefficient of thermal expansion. This means that it does not easily expand or contract when exposed to changes in temperature, making it resistant to thermal stress and ensuring its stability over time.
