Aluminium alloy rheocool
Rheocool
The alloy is developed for 5G and EV´s where the high thermal conductivity is required. The higher the thermal conductivity gets the lesser material is to be used due to reduction of fin height in the designs. Typical applications: heat sinks, AC/DC converters and electronic housings.
