1. High hardness and wear resistance Hardness:
The Mohs hardness of alumina ceramics is as high as level 9, second only to diamond. Wear resistance: Its wear resistance is 266 times that of manganese steel and 171.5 times that of high chromium cast iron.
2. High temperature resistance and thermal stability
High temperature resistance: The melting point of alumina ceramics is as high as 2050 ºC, and it can maintain stable performance at a high temperature of 2000 ºC. Thermal stability: It has a low coefficient of thermal expansion and can maintain structural stability under extreme temperature changes.
3. Lightweight design Density:
The density of alumina ceramics is only 3.6-3.8g/cm ³, which is over 50% lighter than steel. For example, using alumina ceramic components in airplanes can reduce weight by 30% and significantly improve fuel efficiency.
4. Corrosion resistance and insulation properties Corrosion resistance:
Excellent resistance to strong acids, alkalis, and salt media, suitable for chemical reactors, anti-corrosion valves, etc. Insulation: With a resistivity of ≥ 1 × 10 ^14Ω· cm, it is the preferred material for high-frequency electronic device substrates.
5. High cost-effectiveness Cost effectiveness:
Its long lifespan and low maintenance characteristics significantly dilute long-term costs.
6. Customized processing Precision machining:
Through processes such as dry pressing, injection molding, and 3D printing, complex shaped precision components can be made to meet the needs of high-end fields such as semiconductors and medical equipment. Quick response customization: Enterprises can customize ceramic parts according to equipment parameters, reducing adaptation costs.
7. Environmental Protection and Sustainability Low carbon production:
The raw materials for alumina ceramics (alumina powder) are widely available, and the energy consumption of sintering process is lower than that of metal smelting. Recycling: Waste ceramics can be crushed and recycled as raw materials to avoid pollution risks caused by metal material waste
Mechanical and structural ceramics: used for bearings, sliders, seals, etc., to reduce failures and downtime.
Chemical and high-temperature industries: used as refractory materials, insulation materials, chemical reactor liners, and pipeline fittings.
Electronics/Power: Used for electronic substrates, insulation sleeves, etc., providing high insulation performance.
Medical: Used for artificial joints, dental implants, etc., with excellent biocompatibility.
Aerospace: Used for engine components, turbine blades, etc., to enhance the reliability of power systems
Semiconductor production: growing crystals or depositing thin films on thin substrates.
