Advantages of Alumina Ceramic

Alumina ceramic (Al₂O₃ ceramic) has core advantages including excellent mechanical strength, high temperature resistance, good electrical insulation, and strong corrosion resistance, making it widely used in industries like automotive, electronics, and machinery.

Its specific advantages are detailed as follows:

• Superior mechanical properties: It has high hardness (Mohs hardness 9, second only to diamond) and wear resistance, with a compressive strength of 2000-4000 MPa. For example, as a bearing material, it can resist friction and impact, and its service life is 3-5 times longer than that of traditional metal bearings.

• Excellent high-temperature resistance: It can maintain stable performance at high temperatures, with a melting point of about 2050°C and a long-term use temperature up to 1600°C. It is suitable for high-temperature scenarios such as automotive exhaust treatment components and industrial furnace linings.

• Outstanding electrical insulation: It has high volume resistivity (≥10¹⁴ Ω·cm at room temperature) and low dielectric loss, which is an ideal material for electrical insulation parts. For instance, in automotive battery systems, alumina ceramic substrates/separators can effectively isolate current and prevent short circuits.

• Strong chemical corrosion resistance: It is resistant to corrosion by most acids, alkalis, and organic solvents (except hydrofluoric acid and strong alkalis at high temperatures). This makes it suitable for harsh environments such as automotive fuel delivery systems and chemical fluid transmission components.

• Good thermal conductivity and thermal shock resistance: Its thermal conductivity is about 20-30 W/(m·K) (higher than most ceramics), and it can withstand rapid temperature changes (thermal shock resistance ≥150°C). In automotive electronic cooling systems, it can quickly transfer heat and avoid component damage caused by temperature fluctuations.
