  • Rotationally symmetrical hollow body made of a deformable permanently magnetic alloy and its use and production process
    Patent number: 7942981
    Abstract: A seamless, rotationally symmetrical hollow blank formed by a non-cutting operation from a deformable permanently magnetic alloy is provided, said alloy consisting essentially of 5.0 to 20.0 percent by weight cobalt, 20.0 to 35.0 percent by weight chromium, for the remainder iron and impurities caused by melting and/or by chance. The seamless hollow body is suitable in particular for use in hysteresis clutches, hysteresis brakes, and position measuring devices. Furthermore, non-cutting shaping processes for producing the seamless rotationally symmetrical hollow body are provided, with roller spinning being preferred.
    Type: Grant
