Tape, circle, wire 52K12F

Tape, circle, wire 52K12F

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):

C Si Mn Ni S P Cr V Co
Not more than 0.12 Not more than 0.5 Not more than 0.5 Not more than 0.7 Not more than 0.02 Not more than 0.025 Not more than 0.5 11.6… 12.5 52… 54

To buy a tape, a circle or a wire made of a precision magnetically-hard alloy grade 52K12 °F, AvecGlob Company offers. The supplier provides a guaranteed shipment of products to any point. installed by the client.
