Custom-Structured Alumina Ceramic Rod manufactured by Shenzhen Haorui Industrial Technology Co., Ltd. with CNC precision machining.
Length: 84mm
Diameter: 43mm
Structure: The rod features four machined faces:
Two faces include precisely drilled holes (for alignment, mounting, or fluid paths)
The other two faces have fine grooves, ideal for heat dissipation, guiding, or functional integration
Made of 99% high-purity alumina, this rod offers excellent electrical insulation, high-temperature resistance, corrosion resistance, and dimensional stability.
It is widely used in semiconductors, optical communication, electronic fixtures, biomedicine, and other precision industries.
Custom non-standard designs including holes, slots, and tight tolerances (±0.01mm) are supported based on drawings.
✅ Material: 99% high-purity alumina (Al₂O₃) ceramic
✅ Precision Machining: Threaded center and mounting holes processed with ultra-tight tolerances
✅ Excellent Insulation: Ideal for electrical and thermal isolation
✅ High Temperature Resistance: Withstands temperatures above 1600°C
✅ Corrosion & Wear Resistance: Durable in chemically aggressive or abrasive environments
✅ Fine Surface Finish: Ground and polished for smooth, professional-grade surface
