Offers a combination of good mechanical and electrical properties leading to a wide range of applications. Alumina can be produced in a range of purities with additives designed to enhance properties. It can be formed using a wide variety of ceramic processing methods and can be machined or net shaped formed to produce a wide variety of sizes and shapes of component. In addition it can be readily joined to metals or other ceramics using metallising and brazing techniques.

LM Ceramic 124
A Magnesium Alumina Silicate material. Its most important feature is that it has a very low coefficient of thermal expansion and excellent resistance to thermal shock. It is also similar to Steatite in that it is relatively low cost, has good electrical insulation properties, has moderate mechanical properties and temperature resistance, and can readily be formed in a variety of shapes. In particular it can be made in high volume through cost-effective extrusion or dry-pressing methods.
