Pink Fused Alumina For Grinding

Pink Fused Alumina For Grinding

This Pink Fused Alumina For Grinding, also known as chromium fused alumina, is an alumina with almost no Cr2O3. This pink fused alumina has higher hardness and lower toughness than brown fused alumina. It also has better cutting ability. Its particle shape is sharp and angular. It is particularly suitable for the manufacture of vitrified bonded abrasives of work hardened steels and alloys with high tensile strength.

Product description:

1. This Pink Fused Alumina For Grinding, also known as chromium fused alumina, is an alumina with almost no Cr2O3. This pink fused alumina has higher hardness and lower toughness than brown fused alumina. It also has better cutting ability. Its particle shape is sharp and angular. It is particularly suitable for the manufacture of vitrified bonded abrasives of work hardened steels and alloys with high tensile strength. It can also be used for tool grinding, sawing and edge grinding applications, precision grinding, profile grinding, slot grinding, tooth surface grinding, knife segments and dry grinding of mounted wheels.

2. The grinding tool made of Pink Fused Alumina For Grinding has excellent durability and high processing cleanliness. It is made by adding chromium oxide to high purity alumina during the melting process. The amount of chromium oxide added affects the color of the final product as well as the toughness of the particles. As the amount of chromium oxide added increases, the toughness of the Pink Fused Alumina For Grinding increases.
