custom01001
Made from 99.5% or higher purity alumina, offering excellent wear resistance, corrosion resistance, and high-temperature stability.
Low contamination properties prevent damage to sensitive materials like semiconductor wafers.
Processed using CNC precision machining and fine grinding to achieve high dimensional accuracy, with tolerances up to ±0.01mm.
High surface smoothness reduces particle adhesion, enhancing durability and performance stability.
High hardness (Mohs hardness 9) makes it scratch-resistant and highly durable.
Excellent strength and bending resistance allow it to withstand significant loads and mechanical stress.
Excellent insulation performance with a low dielectric constant, ensuring stability in high-voltage environments.
Anti-static properties prevent wafers and other precision components from attracting particles during handling.
Can withstand temperatures above 1600°C, making it ideal for semiconductor manufacturing, high-temperature furnaces, and vacuum environments.
Highly resistant to most acidic and alkaline solutions as well as corrosive gases, meeting the demands of specialized industrial applications.
Lower density compared to metals, reducing overall weight while maintaining structural strength, improving equipment flexibility and stability.
Primarily used for semiconductor wafer handling, optoelectronics, precision equipment, and cleanroom environments, meeting the strict requirements of high-end manufacturing industries.
Shenzhen Haorui Technology specializes in high-precision alumina ceramic handling arm manufacturing, offering customized production to ensure stable product quality and meet your application needs. For inquiries or technical consultations, feel free to contact us!
