Product Description

Permendur Soft Magnetic Alloy Round Bar with High Saturation ASTM A801



Permendur is an equal grade of HiperCo50-ASTM A801 Type 1 UNS R30005.

A-ONE ALLOY supplies Permendur round bar with diameter range from 10mm to 500mm. And, for customized sizes, please contact our sales department for confirmation. 

In fact, we are working with one customer to produce Permendur bar of diameter 2mm.


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. 


We provide special service for R&D projects and MOQ could be lowered to 5kg for these projects.

We keep in stock of round bar diameter 24mm, 39mm and 45mm.


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).
