Magnetic alloy hollow body for e.g. hysteresis brake, has five to twenty percent of cobalt, twenty to thirty five percent of chrome, and iron combined with impurities left over from fusion forming remaining percent of total weight of body

摘要

Hollow body has 5.0 to 20.0 percent of cobalt and 20.0 to 35.0 percent of chrome, and iron combined with impurities left over from fusion form remaining percent of total weight of the body. Body is constituted of 5 percent of Zr, Ti, Hf, V, Nb, Ta, Mo, W, Mn, Si, Al, Ni, Sn, Cu, Zn, Ge, B and lanthanide element of the total weight of the body. Body has a wall with thickness lesser than 3 millimeter and a circumference lesser than 350 millimeter. An independent claim is also included for a method for fabrication of a magnetic alloy hollow body.
