Alumina Al2O3 substrate

Alumina Substrates

Final Advanced Materials supplies a wide variety of substratesaluminazirconia, and aluminium nitride. All our substrates are produced by laser cutting. It is possible to order plates in standard dimensions, or for parts to be cut to a customized design, whether for a prototype or for series production.

Final Advanced Materials has machining facilities which guarantee ISO 9001-certified quality. Our tooling and our expertise permit the production of the most complex components from your plans.

Alumina substrates are highly rated for their good chemical and mechanical resistance. They can be employed for the construction of furnaces, in medical technologies, in electronic sensors, in catalysers, in SOFC fuel cells and for the filtration of liquids.

Two types of alumina substrates are available:

Sintered High-Density Alumina

This substrate is available in the form of two products, the alumina content of which varies between 96 and 99.6 %. Whichever the product, these materials are distinguished by their high resistance to corrosion and abrasion. Moreover, they show good mechanical strength, and can be employed as electrical insulators. They show very low adherence and, by nature, feature exceptional flatness. Finally, alumina substrates show good thermal conduction.

High-density alumina substrates are available in various thicknesses (0.15 – 0.25 – 0.38 – 0.5 – 0.76 – 1 – 1.27 – 1.52 – 2 mm) and in dimensions ranging from 50.8 x 50.8 mm to 168 x 168 mm.

Sintered Porous Alumina

A porous alumina substrate has mechanical, electrical and chemical properties which are similar to those of high density alumina. However, this product is distinguished by its lightness. Its porosity makes it a material of choice for the filtration of gases and liquids, and for the homogeneous diffusion of a fluid.

Porous alumina substrates are available in various thicknesses (1 – 1.5 - 2 mm) and in dimensions ranging from 100 x 100 mm to 168 x 168 mm.
