Permendur 49 is an alloy with nominal composition 49% cobalt, 49% iron and 2% vanadium which combines high saturation with high permeability. It can be supplied as forged section, or strip normally in the range 0.1 to 1.0 mm (0.004 to 0.94 in.) thickness. This datasheet provides information on composition, physical properties, elasticity, and tensile properties. It also includes information on heat treating and machining. Filing Code: FE-126. Producer or source: Carpenter Technology Corporation.

HS 50 alloy was developed to provide an increase of approximately 0.1 T (1000 G) in saturation magnetization compared with standard Permendur 49. The heat treatment of HS 50 can be carried out at a higher temperature, which gives increased permeability and lower coercive force. The mechanical properties are superior to those of Rotelloy 3. For applications where low loss is required, a thinner gage strip can be used to compensate for the lower resistivity compared with Rotelloy 3. This datasheet provides information on composition, physical properties, elasticity, and tensile properties. It also includes information on high temperature performance as well as heat treating and machining. Filing Code: FE-130. Producer or source: Carpenter Technology Corporation.

Permendur 24 has a nominal composition of 24% Co and possesses the highest ductility of the cobalt-iron alloy range. Although it requires a higher magnetizing field than the 49% alloy to reach saturation, it finds applications where ductility and price are the prime considerations. It is available as strip or forged section. This datasheet provides information on composition, physical properties, elasticity, and tensile properties. It also includes information on heat treating and machining. Filing Code: FE-127. Producer or source: Carpenter Technology Corporation.

PERMENDUR V is a cobalt/iron/vanadium soft magnetic alloy. It has a high saturation flux density, low DC coercive force, high permeability at high inductions and a desirably low magnetostrictive coefficient. This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on heat treating. Filing Code: Co-85. Producer or source: Spang Specialty Metals.

Hiperco 50 is a cobalt-iron-vanadium soft magnetic alloy for high flux levels. It has high permeability at high inductions and low d-c coercive force. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on forming and heat treating. Filing Code: Co-50.
