Cold Rolled Nickel Alloy Alloy Mu W.-Nr. 2.4545
1. Application examples
With the highest technically achievable permeability and a very low coercive field strength, the material 2.4545 is ideal for shielding against magnetic interference fields and for toroidal cores in instrument transformers and relays.
Further application examples:
general components in electrical engineering and electronics where a low coercivity is required.
The material is not suitable as a spring material.

The Alloy 2.4545 = Alloy Mu should not be used for springs or mechanically stressed components.
The highest application temperature is around 150° Celsius. Please note that Young's modulus values drop as temperature increases.
8. Physical properties
Density: 8,70 g/cm³
Thermal conductivity: 32 W/(m °C) depending on the temperature
Heat capacity: J/(kg °C) medium value at 50 – 100 °C
Thermal expansion: 12 x 10 -6 (between 20 - 100 °C)
E-Modul: 200 kN/mm²
Electric resistance: 55 µOhm x cm depending on the temperature
saturation flux density : 0,8 T
Relative permeability μr: 80 000 - 480 000 (annealed, at 50 Hz)
Curie-Temperature: 410 °Celsius
9. Blanking
We recommend a punch-to-die clearance of 4-10 % of the strip thickness.
The corner radius should be at least 0.25 mm and the punching die should be at least twice the strip thickness.
The pieces should then be tumbled to receive a good edge roundness.
10. Laser cutting
This alloy can be laser cut by solid state lasers.
11. Photo etching
This alloy is very easy to etch.
12. Bending
The material 2.4545 can be easily bent or deep-drawn in the annealed condition. Intermediate annealing should be carried out in the case of strong deformations.
Final annealing is required to set the optimum magnetic properties, during which the temperature, time and also the cooling conditions must be strictly adhered to.
13. Flat grinding
Since the material 2.4545 can be magnetized, it can be clamped on magnetic clamping plates of surface grinding machines.
Due to the small tape thickness, however, this is not recommended.
14. Welding
This alloy can be welded easily.
15. Corrosion resistance
The alloy 2.4545 has a good corrosion resistance at normal athmosphere.
