Products feature
Darker color-easy to distinguish
One of the most prominent features of black corundum alumina oxide is its dark color, which is caused by the high concentration of iron in the material. This color also makes it easy to distinguish from other types of abrasive materials, which can be beneficial for quality control purposes.
Creates smooth surfaces on metal parts
Another advantage of black corundum alumina oxide is its ability to create a smooth, scratch-free surface on metal parts, making it a popular choice for finishing and polishing applications.
Hardness and durability
Its hardness and durability make it an excellent choice for construction industry, as it can withstand the high pressures and temperatures involved without breaking down or losing its cutting edge.
Abrasive resistance
Other benefits of black corundum alumina oxide include its extreme resistance to wear and tear and its ability to maintain its shape and size over time. This makes it a cost-effective material that can be used for prolonged periods without needing to be replaced.
Products Application
Manufacture of grinding wheels, sandpaper and other abrasive tools, construction industry - cutting, shaping stone and concrete.
