Buy at affordable prices from the manufacturer of various types of rolled products — tape, circle, wire — made of precision magnetically-hard alloy grade 52K12 °F offers the company AvecGlob. The supplier guarantees the timely delivery of products to any address specified by the consumer.

Composition and application

Precision magnetically-hard alloys of 52K12 °F grade are intended for use in permanent magnets with small overall dimensions at operating temperatures up to 480 ^° C. They provide optimum performance in conditions where small magnetic materials with coercive force are required, including magnetic couplings / anti-theft devices, measuring and guitar strings.

The alloy is produced in a wide assortment of sizes and profiles. The 52K12 °F alloy based on cobalt, additionally doped with vanadium, is mechanically rigid, durable and stable over a wide temperature range. The main properties of the alloy are determined by heat treatment regimes, including magnetic orientation and coercive force. This allows us to satisfy a variety of mechanical, surface, magnetic and other requirements.

This alloy is an adequate replacement for Vicalloy and Cunife alloys intended for similar purposes.

Chemically, the composition of the alloy 52K12 °F, which meets the technical requirements of GOST 10994−74, is given in the table (numerical data — in percent, iron — rest):
