bercotherm® resistance wire
Versatile resistance wires for different applications areas
With bercotherm®, Berkenhoff GmbH has developed special resistance alloys. The main task of bercotherm® resistance wires is to convert electrical energy into thermal energy. Applications like this exist in many areas. There are different requirements regarding temperature ranges, mechanical requirements, diameters, and much more. With bercotherm®, we offer our customers resistance wires made of various alloys. The resistance wires can be used in a variety of ways and are suitable for applications such as electric blankets, underfloor heating systems, seat heating, or electrofusion sockets.
Advantages of bercotherm® resistance wire
Optimizing costs by selecting intelligent alloys
- Not all applications will require the use of expensive Cu-Ni alloys
- We offer nickel-free alloys which may significantly reduce the material price
Optimizing costs using higher conductivity
- An increase in conductivity will enable a thinner wire diameter to be used
- Thinner bercotherm® wires have a lower weight per meter – allowing more meters to be produced from one kilogram of wire
Optimizing costs using higher mechanical strength
- The range of bedra alloys include materials with significantly higher mechanical strengths.
- The high strength bercotherm® alloys make it possible to achieve the same specified requirements compared to the classic CuNi alloys with thinner dimensions. This results in more meters of wire per kilogram
Optimizing weight through miniaturization of wire
- Our bercotherm® alloy range – with superior electrical and mechanical properties - offers the opportunity to reduce the cross-section of the wire (mm²), resulting in weight savings.
- Excellent solutions for applications requiring aggressively reduced weights without sacrificing performance
Our applications
- Electric blankets
- Underfloor heating
- Seat heating
- Gutter heating
- Electrofusion sockets
- Your application
