Pink Fused Alumina (PFA) is a relatively new product in the grinding industry. It is produced by fusing alumina with a small amount of chromium oxide, resulting in a pink-colored abrasive that offers unique properties and exceptional performance.
Pink fused alumina is an excellent choice for grinding and polishing applications in the automotive, aerospace, and medical industries. Its superior hardness, toughness, and wear resistance make it ideal for the high-demanding precision grinding tasks. PFA is also widely used for sandblasting and shot blasting, where it provides an efficient and controlled surface finish.
Compared with traditional abrasives such as white fused alumina and brown fused alumina, pink fused alumina has several advantages. The pink color of PFA is due to the presence of chromium oxide, which enhances its toughness and grain-wear resistance. Also, PFA has a higher purity and lower impurity content, resulting in a lower wear rate and better surface finish.
Another significant advantage of pink fused alumina is its lower heat generation during grinding. As pink fused alumina has excellent thermal conductivity, it dissipates heat better than other abrasives, reducing the risk of surface damage and cracking on workpieces. This leads to an increased tool life and improved productivity.
Pink fused alumina is available in various grit sizes, shapes, and packaging, making it suitable for different grinding and polishing applications. The most common shapes are grains, powders, and micro powders, while the grit sizes range from F24 to F1200.
