Permalloy Sheet Plate Strip
Permalloy is the term for a nickel iron magnetic alloy. Generically, it refers to an alloy with about 20% iron and 80% nickel content.
Permalloy Sheet Plate Strip is a soft magnetic alloy wire with exceptionally high magnetic permeability. Permalloy wire has a low coercivity, near zero magnetostriction, and significant anisotropic magnetoresistance. The low magnetostriction is critical for industrial applications, where variable stresses in thin films would otherwise cause a ruinously large variation in magnetic properties.
To ensure the quality of our product, we can produce the product with raw materials from the international suppliers. Every batch of product can be tracked to the original raw material supplier. We co-operate with international suppliers like Allvac(ATI), Bohler, Carpenter, Dunkirk, Gloria, OttoKumpu, SMC, ThyssenKrupp VDM, Valbruna, etc.
