Zirconia alumina abrasive is made of zirconium oxide, aluminum oxide and other materials through high temperature sintering. Zirconia alumina abrasive is a high-quality abrasive material that is widely used in various grinding processes.
Zirconia alumina is an ideal choice for heavy-duty grinding, mainly because zirconia alumina has a hardness of about 9.0 or above, has extremely strong wear resistance, can maintain a long service life during the grinding process, and produce good grinding results. Its structure is dense and strong, and it can withstand large external forces without being easily broken. At the same time, it has good thermal shock resistance and can quickly change between high and low temperatures without cracking or breakage. These characteristics make zirconia alumina perform well in heavy-duty grinding.
Zirconia alumina abrasive is a composite oxide of aluminum oxide and zirconium oxide. It is made of bauxite (or alumina powder), zircon sand, anthracite and iron filings as raw materials, and is smelted at high temperature in an electric arc furnace, and the melt is rapidly cooled and crushed and granulated. It is a microcrystalline structure supported by ZrO2-AL2O3 coarse-grained structure. This abrasive is grayish white, with high toughness, high strength and good wear resistance.
Zirconia alumina model: AZ25, AZ40
Zirconia alumina segment sand: 1-3, 3-5, 5-8, 1-0, 0.5-0, 200#-0, 325#-0, etc.
Zirconia alumina particle size sand: 5#-24#, 30#-100#, F sand, P sand
Application of zirconia alumina abrasive in heavy grinding:
Improve the hardness and wear resistance of the grinding wheel : Zirconia alumina grinding wheel can significantly improve the hardness and wear resistance of the grinding wheel, extend its service life, reduce the frequency of replacement, and improve production efficiency .
Enhance the compression and grinding resistance of the grinding wheel : Zirconia alumina grinding wheel performs well in heavy-load grinding, can maintain stable grinding performance, and improve processing accuracy and surface quality .
Optimize grinding performance: Zirconia alumina grinding wheels have strong self-sharpening properties and are suitable for grinding and polishing of a variety of materials. They can more effectively remove materials from the workpiece surface and improve grinding efficiency and processing quality.
High temperature and corrosion resistance: Zirconia alumina has good high temperature and corrosion resistance, and can remain stable in high temperature and corrosive environments. It is suitable for grinding special workpieces such as high-temperature alloys and corrosion-resistant materials.
In addition, zirconia alumina also has excellent resistance to melt erosion, chemical stability and low thermal conductivity, which enables it to maintain good performance in various extreme environments. These characteristics make zirconia alumina an ideal choice for heavy-duty grinding, and it is widely used in automotive wheels, engineering machinery parts, steel structures and ships.
