Product Description
Functional Features
01 Impact resistant and high toughness
It possesses excellent impact resistance, being more shatter-resistant than most ceramic materials, making it suitable for use as a sharper and longer-lasting knife. It also exhibits higher fracture toughness, possessing the ability to resist fracture under external forces.
02 High strength and high hardness
It has high bending and compressive strength, can withstand large pressure loads without cracking or deforming, and is harder and more wear-resistant than most metal materials.
03 Good thermal conductivity and high temperature resistance
Alumina ceramics possess excellent high-temperature resistance: they maintain stable physical and chemical properties under high-temperature environments. They can generally withstand temperatures above 1000°C.
04 High mechanical strength
It can withstand significant pressure and impact, which makes it widely used in many industrial fields.
05 Corrosion resistant
It has excellent resistance to acids, alkalis and corrosion, and will not undergo significant dissolution or corrosion.
06 Biocompatibility
Alumina ceramics have good biocompatibility with human tissues and will not cause allergic or rejection reactions. This makes them widely used in the medical field, such as in artificial joints and dental restorations.
07 High temperature stability
Alumina ceramics exhibit excellent performance at high temperatures, withstanding high-temperature thermal shock and rapid temperature changes without cracking or deformation, thus possessing long-term stable performance in high-temperature environments.
Scope of Application
Our products shine everywhere.
