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.

Rotelloy 5 nominally contains 50% Co and has been specially developed as a high-strength rotor material for machines operating at high speeds. The alloy is less suitable for stator applications since it has higher losses than Rotelloy 3. In some cases, this can be overcome by the use of thinner strip. 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-129. Producer or source: Carpenter Technology Corporation.

Rotelloy 3 has the same composition as Permandur 49 and was specifically developed for aircraft generator rotor and stator laminations. In addition to a slightly improved magnetic performance, this grade is supplied with guaranteed minimum mechanical properties. This alloy complies with requirements of ASTM A 801. It is available in strip form only. This datasheet provides information on composition, physical properties, and tensile properties. It also includes information on machining. Filing Code: FE-128. 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 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.

Hiperco Alloy 15 is a development in soft magnetic alloys that combines the properties of high saturation, magnetization, high electrical resistivity, and lower cobalt content. This datasheet provides information on composition, physical properties, elasticity, and tensile properties. It also includes information on forming and heat treating. Filing Code: FE-124. Producer or source: Carpenter Technology Corporation.

Carpenter AerMet 310 alloy has higher strength and hardness while exhibiting good ductility and toughness when compared with AerMet 100 (see Alloy Digest Fe-107, April 1994). The alloy should be considered for armor, structural tubing, and members. This datasheet provides information on composition and tensile properties as well as fracture toughness. It also includes information on corrosion resistance as well as forming and machining. Filing Code: FE-122. Producer or source: Carpenter.
