Tungsten Carbide This is virtually the only metal machined by our company as it is almost unique amongst metals in that it cannot be turned or drilled using normal metalworking techniques. It is usually machined using diamond wheels such as we use for all our other ultra-hard materials and, as a result, it falls comfortably within our scope.
Aluminum Silicon Carbide (AlSiC) metal matrix composite (MMC) materials have a unique set of material properties that are ideally suited for electronic packaging appliions requiring thermal management solutions. The AlSiC coefficient of thermal expansion (CTE
Aluminium Nitride With its properties of electrical insulation and excellent thermal conductivity, Aluminium Nitride is ideal for appliions where heat dissipation is required. In addition, since it offers a coefficient of thermal expansion (CTE) near that of silicon, and excellent plasma resistance, it is used for semiconductor processing equipment components.

Silicon Carbide is available in several forms, each with its own unique properties and benefits: Reaction Bonded Silicon Carbide: has a coarse grain and low production costs. This produces a material that has a lower hardness but with a high thermal conductivity.
Many bonding systems are available that inter-connect the alpha silicon carbide grains and in the case of self bonded refractories, it is mainly in a matrix of silicon and aluminium-silicon glass. The bonds in self bonded refractories have been carefully formulated to give specific properties and subsequent performance criteria in any specific appliion.
The crystal structure of silicon carbide is divided into hexagonal or rhoohedral α-SiC and cubic β-SiC (called cubic silicon carbide). Since α-SiC constitutes many different variants due to the different stacking sequences of carbon and silicon atoms in its crystal structure, more than 70 kinds have been found. β-SiC is converted to α-SiC at 2100 ° C or higher.
