SINTYRON 95% pink Purple Alumina Ceramic Laser Cutting Polished Substrate Sheet Plate

Pink Alumina Ceramic Substrate is a specialized type of substrate made from high-purity aluminum oxide (Al₂O₃) with a distinctive pink hue. This coloration is typically achieved by doping the alumina with a small amount of chromium oxide (Cr₂O₃) or other specific metal oxides.

Product Description

We have specialized in producing alumina (aluminum oxide, or Al2O3) ceramic substrates for more than 15 years, under strict quality

control, using carefully selected high-purity ceramic materials ranging in purity from 94.4% to 99.6%.

All of these ceramic substrates have extraordinary electrical, thermal and mechanical properties, especially excellent thermal conductivity

with a thermal expansion coefficient similar to that of silicon. In addition, one of its unique properties is its excellent surface roughness and

thus excellent bond strength with thin and thick film metallization layers, making it an ideal material for various circuit boards.

The conventional molding method we use is tape casting. We offer various thickness options from small sizes to large sizes. With our well-equipped

production facilities, we have the ability to go from prototyping to mass production in a short period of time.

Prime Characteristics

1. High dielectric strength, low dielectric constant and small dielectric loss.

2. High thermal conductivity, up to 25W/(m·K) at 25°C.

3. High-quality surface with ideal flatness, warpage and roughness.

4. High hardness and excellent bending and breaking strength.

5. Corrosion-resistant, suitable for various harsh environments.

6. Anti-oxidation, never rust in very humid conditions.

7. Different patterns are easily achieved by laser cutting with precise tolerances.

Advantages of alumina substrate:

1. The strength is higher than clay ceramics, the hardness is high, and the wear resistance is good.

2. High temperature resistance, can be used for a long time at 1600 degrees.

3. Strong corrosion resistance.

4. Good electrical insulation performance, especially at high temperatures, can withstand more than 8000 volts per millimeter thickness.

Alumina ceramic Substrate Application:

Used in chip resistor, heat sink, integrated circuit board, potentiometer and other fields.
