Supply Alumina Ceramic Element Parts
My factory looking for distributors.
All products through the German DIN standards: DIN43724 / DIN43725 / DIN40680
Advantages of Alumina Ceramic Element Parts
Alumina ceramic parts can withstand high temperatures (1600 ℃ for long-term use, 1800 ℃ for short-term use), high hardness (Mohs 9) durability, and wear resistance. It has high tolerance to various chemicals, acids, and bases, and exhibits excellent dimensional stability with a low coefficient of thermal expansion (8.2x ㎜.10-6／℃.m).
Applications of Alumina Ceramic Element Parts
1. Alumina Ceramic Parts are used in electrical components such as insulators, substrates, and circuit boards.
2. Alumina Ceramic Parts are used to make mechanical components like bearings, seals, and wear-resistant parts in machinery and equipment.
3. Alumina Ceramic Parts are used in semiconductor manufacturing equipment for components like wafer handling arms.
4. Alumina Ceramic Parts are used in high-temperature environments such as furnace components, heating elements, and thermocouple protection tubes.
5. Alumina Ceramic Parts used in welding and cutting equipment due to their resistance to abrasion, heat, and chemical reactions.
