Description
Customizable Alumina Long Light Plate – High Flatness Precision Ceramic Substrate
Product Overview

Alumina long light plate is a precision ceramic plate manufactured from high-purity alumina (Al₂O₃ content ≥99%) through advanced forming processes including dry pressing or isostatic pressing, followed by high-temperature sintering. The surface undergoes precision grinding and polishing to achieve a mirror-like glossy finish. Characterized by exceptional hardness, density, and dimensional stability, this product can be customized in various lengths, widths, and thicknesses to meet specific application requirements. It is extensively used in high-precision manufacturing sectors including semiconductor equipment, laser devices, and medical instruments.

Core Applications
Application Field Specific Uses Core Advantages
Semiconductor/Electronics Lithography machine substrates, wafer handling platforms, packaging mold backing plates High flatness ensures processing precision, excellent electrical insulation performance
Laser/Optics Laser equipment bases, optical platforms, mirror brackets Good thermal stability, not easily deformed
Medical/Biological Medical testing instrument structural components, sterile operating table panels Corrosion resistant, easy to clean, pollution-free
Mechanical/Mold High-temperature mold backing plates, wear-resistant slide rails, fixture bases High hardness wear resistance, long service life
Core Advantages
  • Ultra-High Hardness, Wear and Scratch Resistant: Alumina ceramic hardness reaches HRA 84-92, Mohs hardness 9, second only to diamond. The polished surface is dense and smooth, resistant to scratches during long-term use.
  • Mirror Finish, Consistent Flatness: Precision grinding and polishing achieve surface roughness Ra ≤ 0.1μm with high flatness meeting strict equipment requirements.
  • Size Customization, Flexible Matching: Customizable according to drawings with lengths up to 1650mm and thickness from 1mm to 240mm.
  • Insulation and Voltage Resistance, Stable Performance: Excellent electrical insulation properties, high withstand voltage, and volume resistivity suitable for high-voltage environments.
  • Temperature and Corrosion Resistant, Strong Adaptability: Stable performance in high-temperature environments, resistant to acids and alkalis (except hydrofluoric acid).
  • Good Rigidity, Not Easily Deformed: High elastic modulus, flexural strength up to 300-350MPa, strong load-bearing capacity with shape stability.

Frequently Asked Questions
Q: Can alumina long light plates be customized to non-standard sizes?
A: Absolutely. We have mature customization capabilities and can produce products of different lengths, widths, and thicknesses according to customer requirements, with maximum length up to 1650mm. Please provide drawings or technical requirements for consultation.
Q: How high a flatness can the light plate surface achieve?
A: Through precision grinding and polishing, we can achieve surface roughness Ra ≤ 0.1μm and flatness up to 0.05mm/100mm. Specific precision can be customized according to your equipment requirements.
Q: Is alumina ceramic plate brittle? Is it easy to break?
A: Alumina ceramic is a hard and brittle material with high hardness but relatively lower impact resistance compared to metals. However, under normal use, its flexural strength of 300-350MPa is sufficient for load-bearing requirements. Avoid local impact and hard object collision during use.
Q: Can the product be processed with holes or steps?
A: Yes. We have mature ceramic precision machining capabilities and can perform complex processing including hole opening, grooving, chamfering, and stepping according to drawing requirements to meet your assembly needs.
