99% Alumina ceramic structural parts
Alias: alumina ceramic suction cups / spiral-grooved heating base
Description：
99% alumina ceramic structural parts are high-strength ceramic components made of alumina with a purity of ≥ 99% as the core raw material, through precision molding and high-temperature sintering. With excellent high temperature resistance, high hardness, insulation and chemical stability, it is widely used in machinery, electronics, metallurgy, medical and other fields, as a key structural unit such as wear-resistant load-bearing parts, insulation supports, and high-temperature protective parts, and can replace metal or plastic components in harsh environments to achieve long-term stable operation.
Features:
1. High strength and hardness
The flexural strength ≥ 330MPa, and the hardness is as high as HRA 85-90, which far exceeds that of ordinary metals and engineering plastics, and is wear-resistant, suitable for high-frequency stress-bearing structural parts such as load-bearing and transmission.
2. Excellent high temperature resistance and thermal insulation
It can work for a long time below 1600℃, has a low linear expansion coefficient (about 7.6×10⁻⁶/℃), does not deform or soften at high temperatures, and has thermal insulation properties, making it suitable for structural support in high-temperature stoves and metallurgical equipment.
3. Excellent electrical insulation and arc resistance
With a volumetric resistivity of ≥ of 10¹⁴Ω・cm and a breakdown strength of ≥ 25kV/mm, it provides stable insulation in high-voltage and high-frequency environments without the risk of arc breakdown, making it an ideal choice for insulating structures in electronic devices.
4. Extremely strong chemical stability
It is resistant to acid, alkali, and organic solvents, does not react with most industrial media, and is suitable for clean or corrosive environments such as chemical equipment and medical devices.
5. Precision structure can be customized
It supports complex shape processing, such as special-shaped parts, porous arrays, threaded holes, step structures, etc., with dimensional accuracy of up to ±0.01mm and surface roughness of Ra≤0.8μm to meet the needs of high-precision assembly.
6. Long-term stability
Alumina ceramic structural parts are stable for a long time in use, and their service life far exceeds that of traditional materials.
Applications:
1. Machinery manufacturing
As wear-resistant bearings, guide rail sliders, sealing rings, etc., it replaces metal parts to reduce friction loss and extend the life of equipment.
2. Electronics and electrical
Insulating struts, chip packaging bases, and sensor housings in high-voltage switches provide insulation and structural support.
3. Metallurgy and high temperature equipment
The shelves, crucibles, and thermocouple protection tubes in the high-temperature furnace are resistant to high-temperature oxidation and thermal shock.
4. New energy field
The firing plate of the lithium battery sintering furnace and the high-temperature insulation bracket in the photovoltaic equipment.
