Key Advantages
99.7% High-Purity Alumina for Semiconductor Grade Requirements
Our ceramic semiconductor arms are manufactured from 99.7% high-purity alumina (Al₂O₃), meeting the exacting material standards of semiconductor fabrication and electronic engineering. The high purity ensures minimal contamination risk, stable electrical insulation, and reliable performance in cleanroom environments.
Superior Performance over Metal Arms
Compared to conventional metal handling arms, our 99.7% alumina ceramic arms deliver: exceptional electrical insulation (high resistivity), outstanding thermal stability up to 1600°C, excellent chemical corrosion resistance to acids and alkalis, non-magnetic properties for sensitive electronic components, and ultra-low particle generation for contamination-sensitive processes.
Three Arm Types for Diverse Handling Needs
Yuanhong offers three standard alumina ceramic arm configurations: Fork Arm for multi-finger wafer transfer and grip applications; Diamond/Blade Arm for smooth surface handling and precision blade-type manipulation; Bar Arm for standard flat carrier and platform applications. All types are available with custom geometry to your exact specifications.
Precision Machining for Electronic Engineering Standards
Every ceramic arm is precisely CNC-machined to tight tolerances with smooth, burr-free surfaces. Precision cutouts, mounting holes, and edge profiles are machined to exact engineering specifications, ensuring reliable fit and repeatable performance in automated semiconductor handling equipment.
Full OEM/ODM Custom Capability
We accept complete OEM/ODM customization — custom arm geometry, cutout pattern, hole positions, thickness, and surface finish. Submit your CAD drawings or physical samples and receive a detailed quote within 24 hours. MOQ starts from 1 piece for prototyping and replacement part orders.
