Alumina Precision Parts
My factory looking for distributors.
Advantage of Alumina precision parts
Alumina precision parts can work normally in high temperature environments (with long-term use temperatures up to 1600 ° C or even higher) without softening, creep, or thermal deformation. Small volume changes during temperature fluctuations, maintaining high-precision dimensional stability. Alumina precision parts can achieve very high surface smoothness (low roughness).
Appliction of Alumina precision parts
Alumina precision parts have an extremely wide range of applications, including high demand precision parts in semiconductor equipment, LED chip manufacturing equipment, lasers, precision machinery, analytical instruments, chemical pumps and valves, food and pharmaceutical equipment, thermal equipment, sensors, and other fields.
