Pink Fused Alumina Oxide
Products Description
Pink fused alumina oxide, also known as chromium steel jade, is a type of abrasive material made from high-quality bauxite and chromium oxide. Its pink color comes from the addition of chromium into the aluminum oxide during the smelting process.
Pink fused alumina oxide is known for its excellent thermal stability and wear resistance, making it ideal for use in high-temperature environments. It is also a non-toxic and environmentally friendly abrasive, making it a popular choice for a variety of applications.
