Precision Drilling Alumina Ceramic Parts
My factory looking for distributors.
Advantages of Alumina ceramic parts
1. The customized service for alumina ceramic parts can flexibly adjust the size, shape, precision and surface treatment method of the parts according to the special parameters of the customer's equipment and the requirements of the working conditions.
2. Alumina ceramic parts have characteristics such as high temperature resistance (1600°C) and corrosion resistance, which can prevent traditional metal materials from deforming or being damaged in harsh environments and reduce the defective rate.
3. Although the initial cost of a single alumina ceramic part may be higher than that of ordinary metals, the wear-resistant service life of alumina ceramics is 5 to 10 times that of steel, which greatly reduces the frequency of shutdown for maintenance and replacement.
4. The low-carbon production process of alumina ceramic parts (such as waste heat recovery technology) reduces energy consumption by 30%, helping enterprises with their green transformation.
Applications of Alumina ceramic parts
1. In the semiconductor field, alumina ceramic parts can be customized into electronic substrates or high-purity vacuum chambers to ensure the cleanliness of chip manufacturing.
2. In the photovoltaic industry, by customizing alumina ceramic guide wheels, the problem of chipping during silicon wafer cutting can be solved, and the yield rate can be increased from 88% to 97%.
3. Processes such as extrusion and injection molding are supported to achieve the precise molding of special-shaped parts of complex alumina ceramic parts, meeting the needs of high-end fields such as medical artificial joints.

FAQ
A1. Ceramics are non-metallic, inorganic materials that are typically composed of a combination of metallic and non-metallic elements. Alumina is a type of ceramic oxide, specifically an oxide of aluminum. It is widely used in various applications due to its excellent mechanical, thermal, and electrical properties.
A2. Because of their excellent chemical stability, alumina ceramicparts are used widely in acid-resistant pump impellers, pump bodies, acid-carrying pipe linings and valves. Aluminum oxide ceramics are used in the manufacture of textile wear parts and knives. This is due to their extreme hardness and wear resistance.
A3. Alumina ceramic parts is a very hard ceramic that is excellent at resisting abrasion and is ideal for wear-resistant inserts or products.
