Description
Brown Fused Alumina is usually brown, brownish red or dark red in color, due to the small amount of chromium, iron, titanium and other impurities. Brown Fused Alumina is less well known in the market than other corundum color variants, such as ruby (red corundum) and sapphire (blue corundum), but it still has some aesthetic and commercial value.Its advantages include:
1. High hardness: Brown Fused Alumina is very hard, ranking 9 on the Mohs hardness scale, second only to diamond. This gives brown corundum excellent wear resistance and durability in both jewelry and industrial fields.
2. Heat resistance:Brown Fused Alumina has good high temperature resistance. It can maintain its physical and chemical properties in high temperature environments, which makes it very useful in high temperature processing and grinding applications.
3. Versatility: Brown Fused Alumina can be used not only as a gemstone for jewelry, but also to make abrades and grinding tools. It can be cut and polished into a variety of shapes for different uses, such as sandpaper, grinding wheels, abrasive powder, etc.
4. Natural color: Brown Fused Alumina has an attractive brown, brownish-red or deep red color. This natural color gives brown corundum a unique appeal in jewelry design and can be used to make unique and personalized jewelry works.
5. Relatively Low price: Compared to other gem-grade corundum variants, such as ruby and sapphire, brown Fused Alumina is priced relatively low in the market. This makes it a more affordable option while still obtaining high-quality gems or abrasive materials.
Overall, brown Fused Alumina is a kind of brown corundum gemstone with high hardness and wear resistance, which has certain application value in the jewelry industry and industry.
