Aluminas
Aluminum oxide ceramics (Al ₂ O3) play an important role in modern materials science and engineering, and are widely used in various fields due to their excellent high-temperature stability, thermal conductivity, and chemical stability. The Mohs hardness is close to 9, second only to diamond and silicon carbide. We provide you with professional and high-performance customized processing services for 95-99.8% alumina and high toughness zirconia toughened alumina products
95-99.8%Alumina （Al₂O₃）
Aluminum oxide ceramics are the most widely used technical ceramics, utilizing their excellent properties such as wear resistance and high hardness, electrical insulation, chemical corrosion resistance, high strength and hardness, with a melting point of up to 2050 ° C. They can maintain excellent performance in high temperature environments. The commonly used aluminum oxide ceramics are classified according to purity: 90% -99.9%. Among them, aluminum oxide with a purity below 97% is more suitable for surface metallization treatment due to its large grain structure, and can achieve processes such as brazing. The surface of high-purity alumina ceramics usually presents a finer texture and can be polished to a roughness of less than Ra0.02. Alumina with a purity higher than 99.8% is widely used in industries such as semiconductors and healthcare. Junjie has many years of experience in processing alumina ceramics and can provide alumina ceramic processing services that can maintain stability and reliability in special scenarios such as mechanical manufacturing, chemical, electronic, and electrical industries

Zirconia toughened alumina (ZTA)
Zirconia toughened alumina is a high toughness alumina ceramic produced by adding 10% -20% zirconia to the alumina powder and firing it. It is manufactured using stress induced transformation of tetragonal zirconia particles. ZTA has higher mechanical strength and wear resistance than ordinary alumina, as well as good high-temperature stability and biocompatibility, making it the perfect choice for pump valve components, seals, and joint implants.
