Mumetal
Mumetal is 80% nickel with additions of iron and molybdenum as main elements in turn this alloy offers an extremely high initial permeability. It is only moderately resistant to moisture and atmospheric corrosion, it used mainly in in transformer cores but is well known for its magnetic properties which are used for shielding electrical components from magnetic fields. "HYMU 80" has a minimum DC permeability of 80,000 at a flux density of 40 gauss when heat treated by the recommended procedure and test in accordance with ASTM 596

Why Choose SZNK Heating Resistance Alloys
All our raw material is made from prime material, not recycle material. We have more than 25 years experience in manufacturing resistance heating alloys.
In the market, not all the NiCr alloys are with standard chemical composition and stable resistance. Professional and reliable is the soul of our business.
1) We achieve consistent production from smelting to complete products, we are able to supply satisfactory products.
2) We have has the world's advanced level of German ALD - VIDP1000 - 8000KG vacuum induction furnace and wire drawing machines from Japan.
3) With our skilled spooling knowhows, we have successfully magnified the take - up weight on spool. For example, even a superfine wire of 0.04 mm in diameter can be wound and shipped on a 3 - 4 kg bobbin, thus immediately contributing to your productive efficiency.
4) In order to prevent a wire from loosening, we have introduced a developed tension controlled systems into our take - up machine and respooling machine.
We think you can anticipate smooth despooling.
5) Rolling mill with 4 stands in tandem is applied to our ribbons (rolled wires) manufacturing.
