Key Material Advantages

Excellent Hardness and Wear Resistance

Sapphire offers excellent resistance to scratching, abrasion and mechanical wear. It is suitable for protective windows, wear-resistant surfaces and components exposed to repeated contact or harsh working conditions.

Wide Optical Transmission Range

Properly polished sapphire can provide good transmission from ultraviolet through visible and infrared wavelengths, making it suitable for optical windows, sensor covers, laser systems and observation ports.

Actual transmission depends on material thickness, surface finish, crystal orientation, wavelength and coating.

High-Temperature Stability

Sapphire maintains good mechanical and electrical properties under elevated-temperature conditions. It can be used in furnace equipment, high-temperature sensors and industrial systems where ordinary glass may soften or lose stability.

Chemical and Corrosion Resistance

Sapphire provides strong resistance to many chemicals and corrosive environments. It is frequently selected for optical and mechanical components exposed to aggressive gases, liquids or cleaning processes.

Electrical Insulation

As an electrically insulating crystal material, sapphire is suitable for electronic substrates, insulating components and applications requiring electrical isolation combined with thermal and mechanical stability.

High Mechanical Strength

Sapphire combines high hardness with good compressive strength, allowing thin components to provide reliable protection in demanding optical and industrial environments.

Sapphire Wafers and Substrates

Sapphire wafers are used in semiconductor, optoelectronic and research applications. They can be manufactured in different diameters, thicknesses and crystal orientations.

Available processing options may include:

• C-plane sapphire wafers

• Small-diameter sapphire discs
• Custom-cut sapphire substrates

When requesting a quotation, please specify the wafer diameter, orientation, thickness, polishing condition, flatness, surface roughness and quantity.

Sapphire Optical Windows

Sapphire windows are suitable for optical systems operating under high pressure, high temperature, abrasive conditions or corrosive environments.

Typical configurations include:

• Round sapphire windows
• Rectangular sapphire windows
• Square sapphire windows
• Thin sapphire cover plates
• High-pressure viewing windows
