Permendur Iron-Cobalt Soft Magnetic Alloy with High Saturation
Permendur is an equal grade of HiperCo50-ASTM A801 Type 1 UNS
R30005.
A-ONE ALLOY supplies Permendur cold rolled strip with minimum
thickness of 0.05mm. We are among the several TOP suppliers in
China who are able to make this thickness. Our customers are from
worldwide including EU&US.
A-ONE ALLOY has rich experience of supply Permendur parts, machined
and heat treated. What's more, we are able to help our customers to
improve the design of product.
Stocked strip of thickness 0.1mm, 0.20mm, 0.35mm.
We could supply the strip with a MOQ of 20kg. The delivery is 45 to
60 days. And, for stocked items, the MOQ is 1kg only! For a R&D
project, it is really helpful!
Permendur is an iron-cobalt alloy used in magnetic components
requiring high permeability at and above 15 kG (1.5 T) or high
magnetic saturation.
In fact Permendur has the highest magnetic saturation of all
soft-magnetic alloys and excels in application where this attribute
is needed. Hiperco 50 maintains its strength after heat treating
making it your best choice for application that experience high
forces (e.g. rotating parts).

Heat treatment of R30005
Heat to the annealing temperature and hold for 4 h. Alloy 1 is
typically heat treated at temperatures between 845 and 865°C. For
some applications, annealing may be performed at temperatures as
low as 715°C. The annealing temperature of Alloy 1 should never
exceed 875°C as the alloy is prone to exhibit poor magnetic
properties if heated above this temperature. Exceptions to this
high-temperature limit, if necessary, should be discussed with the
producer.
