Our alumina substrate has well-balanced properties of insulation, thermal conductivity and breaking strength. Moreover, one of the unique properties is its surface roughness. We can provide the ceramic substrate which is excellent in adhesion with a thin film and thick film metalization due to fine particles.

■Good smoothness / flatness with less porosity. Excellent in adhesion with thin film and thick film materials.
■Less variance in outline, plate thickness, slit pitch, etc.
■Minimal warpage, bending, and undulation.
■Physical and chemical properties are stable even under a hot environment. Excellent in thermal shock resistance. High thermal conductivity and coefficient of thermal expansion similar to that of silicon.
■Superior mechanical strength. Products with higher mechanical strength are also in our lineup.
■Excellent resistance against oil and chemical.
■Excellent in insulation properties, high dielectric breakdown voltage, high surface resistivity / volume resistivity, and small dielectric constant.
■Stable breaking strength, and less variance in shape or dimensions.
■The high reflective substrate, especially suitable for optical applications such as LED, is also available.

 

Alumina (Al2O3) has a wide application due to its versatility and low material cost. Alumina possesses a high melting point, strong hardness, and good chemical stability, making it a good material to withstand high temperature and chemical corrosion. Alumina Plates and Disks are available in different dimensions and thicknesses. Call for custom shapes and sizes.

High temperature and abrasive resistance is good

 

 

Quality assurance:

1. High heat resistance : Zirconia ceramic has excellent thermal stability,which means that it is widely used in areas where resistance to high temperatures is essential.
2. Good wear resistance : Zirconia ceramic is the material of choice for wear parts.
3. High corrosion resistance : It is insoluble in water and only slightly soluble in strong acid and alkaline solutions. Good chemical stability of alumina leads to high corrosion resistance.

Alumina ceramic is the most mature of the engineering ceramics, offering excellent electrical insulation properties together with high hardness and good wear resistance,but relatively low strength and fracture toughness.Alumina ceramics are generally white but may also be pink or ivory.The color is derived from either the sintering additives or impurities in the raw materials.
