Power Electronics & Sensors

Overview of our components for power electronics and sensor technology

Power electronics need reliable thermal management - It is not only engine performance that is increasing in the automotive sector, but also the performance of the computer chips used in power electronics and sensor technology. At the same time, these higher outputs place greater demands on the components in the power electronics modules. This is because the silicon carbide (SiC) technology used requires materials that can cope with their very special properties. Our technologically leading solution for this are components made of aluminium graphite.

Thermally precise. Electronically reliable

The strengths of aluminium graphite in power electronics

Our aluminium graphite materials impress with their low density and thermal properties adapted to SiC. The coefficient of thermal expansion (CTE) of aluminium graphite is also very similar to that of the chip materials used. The absence of a CTE mismatch means that the systems are subjected to far less stress. This is reflected in reliable operation, as well as in an extended service life of the modules and protection of the very expensive silicon carbide.

Developed for the power electronics of tomorrow

The outstanding thermal conductivity of our aluminium graphite components ensures that the heat generated is safely dissipated. We produce customised components in lightweight construction for numerous applications in the automotive sector, such as pin fin coolers, base plates and heat sinks.

With experience into the automotive future

A lightweight that makes a big impression

Aluminium graphite is the perfect material for reliable thermal management in modern power electronics modules. This is not only due to its low thermal expansion and high thermal conductivity, but also to its low density. This results in a 75 per cent reduction in weight compared to copper components. There are therefore many good reasons for our customised designs made of aluminium graphite.
