The Most Well-known Oxide Ceramic Material
99% Alumina fixing plate Ceramic custom machining Flat grinding Precision grooving
This product is alumina ceramic fixed parts, which is non-standard custom-made and requires high precision. Alumina ceramics have the characteristics of wear resistance, high temperature resistance, corrosion resistance and high structural strength, which can replace the metal structural parts ispecial environment.
High temperature resistance
Withstand up to 1600℃.
High hardness
Vickers hardness is higher than 1500HV0.5, its hardness is only second to diamond.
Good wear resistance
Its wear resistance is equivalent to 266 times of manganese steel, which can extend the service life of the equipment.
Light weight
The density is only half of steel, which can greatly reduce the load of equipment.
Reliable quality
16 years precision ceramic processing experience, ISO quality management system certification, quality assurance, zero risk commitment!
SHENZHEN HAORUI INDUSTRIAL provide professional efficient,high-quality services,constantly innovate in technology and products,surpass ourselves,strive for excellence,and achieve a win-win situation.
