Electrical steel strip
Our Electrical Steel Strip can be found where efficient energy generation, transmission or consumption is of utmost importance. This includes generators, transformers, industrial electric motors, electric drives in household appliances and electric car engines.
Precise magnetic properties
Our customers often require individually customized electrical steel strip for their specific applications. Important properties in this context include low losses, high flux density and permeability. With our expertise in electrical steel strip, we can produce products with magnetic properties that are both tailored to our customers' needs and highly efficient. In order to offer the best solutions to match
project requirements, we often help our customers already in the early stages of product development.

HS grades: high-strength electrical steel strip
Very high tensile strength for mechanical loading. Due to their high speeds, electric motors in car engines have additional requirements when it comes to
the mechanical stress to which electrical steel strip can be subjected. To meet these special requirements, we developed extremely strong HS (high strength) variations based on our NO grades.
Yield strengths above 500 MPa (73 ksi)
For modern electric vehicle engines, we combine our expertise in electrical steel strip with our expertise in extraordinary tensile strength. Just think of the rotor teeth, which are subjected to extremely high mechanical stress at high speeds. To meet such demands, we can produce steel strip grades with yield strengths above 500 MPa (73 ksi). Talk to us about what
electromobility ideas you would like to develop. We would be happy to accompany you with our electrical steel strip expertise from the very beginning of your development process.
CDW-PERM® grades - unmatched magnetizability
Highly permeable steel strip grades for improved efficiency.
Waelzholz CDW-PERM® grades are steel strip grades with a particularly high magnetic permeability. We also produce significantly higher polarization at the same energy input with our CDW-PERM® grades compared to standard grades. The result is excellent magnetizability in both grade variations as well as a significant increase in thermal conductivity in the CDW-PERM® variation.
Optimal polarization and thermal conductivity for electrical devices
These high-permeability steel strip grades are ideal for high-performance electrical devices. Due to their high permeability values, they allow for higher motor torques. To top it off, our CDW-PERM® grades have excellent thermal conductivity, ensuring that heat built up during motor operation can easily flow out.
