Wider soft magnetic alloy strip to boost new high-power generators, magnetic bearings

Carpenter Technology Corporation : 04 November, 2004  (New Product)
Wider strip of a critical soft magnetic alloy from Carpenter Technology Corporation offers manufacturers of new-generation, high-speed electrical motors, generators, alternators and magnetic bearings the opportunity to increase power and reduce weight.
Carpenter expects its Hiperco 50 alloy and Hiperco 50-HS alloy strip variation, in widths now available up to 12-in. (320 mm) and thickness of 0.020-in.(0.5 mm) and under, to give engineers the design flexibility to make larger devices. Typical applications include aerospace power generators and magnetic bearings.

The new wide strip is expanded from an industry maximum 10-in. width, which will enable designers to configure larger components in integral units, reducing the need for segmented laminations. Laminations for rotors and stators are generally produced by stamping, laser cutting or wire electrical discharge machining.

Hiperco 50 alloy is well known for its high magnetic saturation. Its companion grade, Hiperco 50-HS alloy, has higher yield strength that may be needed for either power generation or magnetic bearing applications where rotational speeds are exceedingly high.

Both alloy variations are iron-cobalt-vanadium soft magnetic materials, which exhibit magnetic saturation of about 24 kilogauss, high DC maximum permeability and low DC coercive field strength. AC core loss is low in the basic grade, moderate in the higher-strength alloy.

When annealed at 720 to 740C (1328 to 1354F) for about two hours, the original alloy provides a room temperature yield strength of 448 MPa (65 ksi). The HS companion alloy provides room temperature yield strength of 620 MPa (90 ksi) when similarly processed. Both grades have a nominal composition of 2% vanadium, 48.5% cobalt and balance iron, with a small amount of niobium 0.05% for the basic alloy and 0.30% for the HS grade.
