NiFe50 wire, rod, bar supplier

«Auremo» supplier offers to buy NiFe50 wire, rod, bar by wholesale. There is a wide range of half-finished goods in stock. A wire, a rod, a bar are always in stock. You can buy them for the best price from a NiFe50 wire, rod, bar supplier. Buy NiFe50 wire, rod, bar right now! An availability of products and efficiency of delivery are conditioned by a fact that we have offices in Moscow, St. Petersburg and cities of Central Europe. For wholesale customers a price is privileged.


NiFe50 wire, rod are used in modern innovative technologies, at manufacturing the electronic units, household appliances, details of laser techniques and metrologic-measuring equipment. Permalloy NiFe50 is an essential material in manufacturing cores of small-sized and high-power transformers, relay actuators, chokes, details of magnetic circuits. They operate while working at increased induction with a small bias or without it. Possessing a high magnitude of initial permeability, soft-magnetic alloys can magnetize to saturation on weak fields.


NiFe50 permalloy is characterized by an accuracy of chemical composition, a preciseness of manufacture, processing, and absence of residual elements. It is the high-doped alloy. They are manufactured on a basis of iron, nickel, cuprum, niobium, cobalt. Such alloys are smelted in special metallurgic furnaces. Prepared ingots are exposed to forging and cogging. Soft-magnetic alloys have an increased induction of technical saturation and raised magnetic inductive capacity.

Permalloy is smelted in open arc furnace. A usage of special masteralloys gives a material the most precious properties (elastic, magnet, heating, electrical). This steel possesses the balanced technological characteristics due to which it is so popular. Tubes of NiFe50 grade are used in spheres of precision machine tool building, an accurate instrument engineering, innovative technologies.

By virtue of unique physical, mechanical properties, permalloy is widely used in a modern industry. Unique properties of a material are conditioned by its balanced composition. With an appearance of materials of a new generation, there has become a possibility to improve many technological processes and to provide a long-term and reliable work of equipment in a wide temperature range.
