powercore® A

With the fully-processed powercore® standard grades, all important quality features are fully developed. In many cases, magnetic properties are better than those specified in the standards. All properties are extremely uniform thanks to reliable process control and the use of state-of-the-art equipment. The use of hot strip mainly from the casting-rolling line means that low core losses can be achieved even with reduced silicon and aluminium contents. As saturation polarization increases with reduced alloy contents, our grades display higher polarization values despite lower core losses in the upper magnetization level.
