Vacoflux27 High Saturation Induction Soft Magnetic Alloy Cold Rolled Strip

A-ONE ALLOY supplies Vacoflux27 to customers from worldwide.

Vacoflux27 (UNS K92650) is named 1J27 in China. It is a new type of soft magnetic alloy in China even it is already widely introduced by the inventor Carpenter. A-one Alloy is among the several manufacturers who are able to produce Vacoflux27 products in forms of cold rolled strip and round bar.

Vacoflux27 is a better choice when the fabrication is considered when HiperCo50 is somehow has better permeability and coercive force-even the difference is not big. The magnetic saturation of both alloys is nearly identical. And, Vacoflux27 does not exhibit the brittleness of Hiperco50.

Heat treatment 

Vacoflux 27is typically heat treated between 845 and 865°C for the best magnetic performance. It may also be heat treated at temperatures as high as 975°C without the same cautions concerning Vacoflux50. For both alloys, the use of a relatively low heat treatment temperature or reduced heat treatment time provides higher strength but with a sacrifice in magnetic performance. The higher heat treatment temperatures, within the limits stated, generally provide the best magnetic performance but lower mechanical strength.

Cool in the same atmosphere at a rate of 100 to 200°C/h to 500°C or lower and at any rate thereafter to a
temperature of at least 200°C or lower.
