Ruby Aluminium oxide and Pink Fused Alumina is made by aluminium oxide powder, which is electrically fused at high-temperature adding appropriate amount of chromium oxide, etc.
Our PA and RA have the features of good crystallinity, pure color, less impurity, well-distributed particle size composition, low magnetic substance content, high bulk density, and high toughness. They have good reputation in domestic and overseas.
Characteristics:
The abrasive tools made by PA or RA have good durability and the workpieces have high smooth finish.
Good raw materials supply a guarantee in quality. Even size distribution, excellent chemical compositions make the good hardness and toughness, high efficiency and durability.
Application:
It can be used to produce grinding wheel, grinding stone, grinding media, etc.
It is suitable for precision grinding of the measuring tools, machine tool main spindle, instrument parts, thread workpieces and sample plate, etc.
