Semicera’s Black Alumina Ceramic Arm is a high-performance accessory used in semiconductor automation equipment for wafer handling and precision movement. It is made from advanced black alumina ceramic, which offers higher strength and better toughness compared with standard alumina materials.
The ceramic arm is designed for use in cleanroom environments where high precision, low particle generation, and long-term stability are required. It helps ensure stable wafer transfer and positioning during automated semiconductor processes.
This black alumina ceramic arm is a mechanical handling part used in semiconductor automation equipment. It is mainly used to pick, move, and position wafers or precision components during production.
Made from high-strength black alumina ceramic, the arm is stronger and more impact-resistant than standard ceramic materials. It performs well in cleanroom environments where low particle generation, high stability, and long service life are required.
1. High Hardness
Alumina ceramics have a Rockwell hardness of HRA 80–90, which is lower only than diamond and significantly higher than wear-resistant steel and stainless steel.
2. Excellent Wear Resistance
According to industrial testing, alumina ceramics offer extremely high wear resistance, up to 266 times that of manganese steel and about 171.5 times that of high-chromium cast iron. Based on long-term customer applications, they can extend equipment service life by at least 10 times under the same working conditions.
3. Lightweight
With a density of approximately 3.5 g/cm³, alumina ceramics are about half the weight of steel, helping to significantly reduce equipment load and improve system efficiency.
