99% Alumina Ceramic Standoffs and Wear-resistant Alumina Standoff Insulators

Alumina ceramic (Al₂O₃) is an extremely important advanced engineering ceramic material. Its excellent overall performance is used in numerous industrial applications, including structural standoffs, insulating standoffs, and load-bearing standoffs. It is typically classified based on its alumina purity (e.g., 96% or 99%). Higher purity generally improves performance, but also increases cost and processing difficulty.

Our Processing Capabilities

• Insulators and Substrates: Used as insulating and supporting components in circuit boards, power electronic modules (such as IGBTs), vacuum tubes, high-voltage switches, and connectors.
• Semiconductor Equipment: Used in wafer processing, etching, and diffusion processes, they serve as wafer carriers, insulating columns within process chambers, and guide rails, withstanding plasma erosion and high temperatures.

• Wear-Resistant Parts: Used in conveyor rails, bearings, bushings, nozzles, etc., providing support and guidance in high-temperature or severely abrasive environments.
• Sensor Protective Covers: Provide high-temperature and corrosion-resistant protective housings for thermocouples, temperature sensors, etc.

• Used in supports, rollers, crucible supports, etc. in melting furnaces and heat treatment furnaces, withstanding extremely high temperatures.

• Used as insulating and supporting components in medical devices, such as medical imaging equipment (CT and MRI).
• High-purity alumina (e.g., 99.5% or higher) is used in orthopedic implants, such as ball heads and acetabular cups for artificial hip joints.

• Used as insulating support columns and fixed standoffs for laser tubes and high-power lasers.

• Widely used in various experimental fixtures and devices requiring high-temperature resistance, insulation, and chemical corrosion resistance.
