We are manufacturers of anodized aluminum strip (anoxal), which is used as a particularly high-performance conductor material, especially for the construction of electromagnets, generators and transformers. It is extremely thin, particularly thermally conductive and temperature-resistant.
The extremely thin layer of insulation from anoxal results in high dielectric strength and optimum thermal conductivity. There are no hot spots, and the resilience increases, since anoxal can be used at a permanent temperature of 500°C – copper windings are only temperature-resistant up to 180°C.
A weight reduction of up to 50% with a similar size and comparable electrical properties compared to copper coils is possible with anoxal.
The use of anoxal in AC applications as well as for DC applications is guaranteed.
