wood metal

wood metalBeing 80% nickel, with the addition of iron and molybdenum as the main elements, this alloy offers extremely high initial magnetic permeability. It has only moderate resistance to moisture and atmospheric corrosion and is primarily used in transformer cores, but is known for its magnetic properties and can be used to shield 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 in accordance with the recommended procedures and tests of ASTM 596

Why choose SZNK heat-resistant alloy

All of our raw materials are made from high-quality materials, not recycled materials. We have over 25 years experience in manufacturing resistance heating alloys.

In the market, not all nickel-chromium alloys have standard chemical composition and stable electrical resistance. Professionalism and reliability are the soul of our business.

1) We have achieved consistent production from smelting to finished products, and we are able to provide satisfactory products.

2) We have world-advanced German ALD-VIDP1000-8000KG vacuum induction furnace and Japanese wire drawing machine.

3) With our skilled winding technology, we have successfully enlarged the winding weight on the bobbin. For example, even ultra-fine wire with a diameter of 0.04 mm can be transported on 3 - 4 kg spools, instantly increasing your productivity.

4) In order to prevent the wire from loosening, we have introduced the developed tension control system in the wire take-up machine and double wire machine.

We think you can look forward to a smooth offline.

5) 4 tandem rolling mills are used in our strip (rolling line) manufacturing.
