Alumina Substrate — Electrical Insulation
Alumina Ceramic Substrate
Alumina Ceramic Substrate (Type A)
Alumina Ceramic Substrate — Non-MagneticAlumina Substrates Series
Alumina ceramic substrates offer excellent insulation, thermal conductivity and dimensional stability with a flat surface. They can be drilled, diced and metallized, serving as the core insulating and heat-conducting base material for electronic circuits, power devices and heating modules.
- Thermal conductivity
- 20–28 W/m·K
- Dielectric strength
- ≥18 kV/mm
- Thickness range
- 0.25–5 mm
Glazed Alumina Ceramic Tube
Glazed Alumina Ceramic Massage Head
Alumina Ceramic Spacer
Alumina Ceramic Sealing PartAlumina Glazing Parts & Sealing Parts Series
Glazed alumina parts carry a high-temperature glass glaze over the substrate, giving a smoother surface, better airtightness and corrosion resistance. Surface porosity is reduced while insulation and anti-fouling performance improve — widely used in sealing, insulating and corrosion-resistant applications.
- Glaze finish
- Ra≤0.1 μm
- Hermeticity
- High (vacuum-tight)
- Glaze colors
- White / black / custom
