Hiperco® 50, 50A & 50 HS Strip & Coil

Hiperco 50, Hiperco 50A and Hiperco 50 HS are soft magnetic alloys Taashvi stocks in the form of strip coil. We stock the strip coil form of Hiperco 50 in diameters that range from 0.004″ to 0.020″. Hiperco 50A and Hiperco 50 HS strip coil is also available from stock in diameters that span from 0.006″ to 0.014″.

The chemistry differentiation of these three Hiperco 50 alloys provides each with its own unique key properties for selection of your strip coil as a component in your application.

  • Hiperco 50 contains a small amount of niobium (0.05%) which allows for mechanical strength and magnetic properties.
  • Hiperco 50A is categorized as “high purity” since no alloying additions are made for grain refinement and low tramp element concentrations provide superior magnetic properties.
  • Hiperco 50 HS also contains the addition of niobium (0.30%) for grain refinement during mill processing and final heat treating resulting in a higher yield strength that Hiperco 50.

Hiperco® 50, Hiperco® 50A & Hiperco® HS Applications

Taashvi is a leading supplier of soft magnetic alloys including Hiperco® 50, Hiperco 50A and Hiperco 50 HS. Given the high magnetic saturation properties of these alloys, they have been employed in many applications with high rotational speeds. Examples of applications where these alloys have been employed are provided below:

Hiperco 50 is a component in commercial aircraft safety systems including a “RAT” (ram air turbine) and in the “APU” (auxiliary power unit). On January 15, 2009 shortly after takeoff from New York’s LaGuardia Airport, US Airway flight 1549 was attacked by bird strikes that resulted in loss of power in both main engines. This plane had both its APU and RAT electric generators made with Hiperco 50 rotors and stators. Fortunately, the RAT and APU provided the

emergency power that enabled Captain Sullenberger to make the needed flight maneuvers to bring US Airway flight 1549 down safely. In addition, the airplane’s engine generators contain Hiperco 50, but since they are driven by the main engines, they could no longer supply power.

Hiperco® 50 Applications

Hiperco 50A is a beneficial alloy for magnetic cores in electrical equipment requiring high permeability at high magnetic flux densities. It is also found in tape cores where lowest A.C. losses and high permeability at high inductions are desired.

Hiperco® 50 HS Applications

Alloy strip should be considered a candidate for use in the manufacture of rotor laminations for aircraft power generation applications, as well as for magnetic bearings. Laminations are stamped from cold rolled strip. They must be final annealed in a protective atmosphere or vacuum environment at a temperature which will provide an optimum combination of magnetic and mechanical properties to withstand the high stresses encountered in service.

Ferromagnetic Annealing and In-Process Heat Treating Hiperco 50, 50A and 50 HS

Hiperco 50 and Hiperco 50 HS

It is important to avoid any contamination of the finished parts during the heat treatment. All parts must be cleaned thoroughly to remove any surface contaminants prior to annealing.

Batch heat treating in a sealed retort or welded box-type furnace is recommended. Thoroughly degreased and cleaned laminations can usually be stacked without an insulating media separation. To obtain the best degree of lamination flatness, a light weight can be placed on top of the stack.  It may be necessary to determine the correct amount of weight to assure that there is no sticking of the laminations within the stack height employed.

A dry hydrogen atmosphere or a high vacuum is recommended to minimize oxide contamination of the parts during annealing. When hydrogen is employed, the entry dew point should be dryer than -60°F (-51°C) and the exit dew point dryer than about -40°F (-40°C) when the inside retort temperature is above 900°F (482°C).

Anneal parts at 1300/1600°F (704/871°C) for 2 to 4 hours in dry hydrogen or vacuum and cool at 250/400°F (139/222°C) per hour until 600°F (316°C) is reached.  After any cooling rate can be employed. The exact heat treat temperature to be employed will depend upon the application and the desired compromise between magnetic and mechanical properties. With increasing temperature from 1300° to 1600°F (704° to 871°C), the magnetic properties improve while the yield and tensile strengths decrease. The temperature at no time should exceed 1600°F (871°C) as an upper limit, as the soft magnetic characteristics start to decline due to formation of an austenitic phase.

For certain A.C. applications, improved magnetic characteristics and/or lower core loss are realized by creating a thin oxide layer on the surface of the annealed laminations. The surface oxide layer can be achieved by heating in an oxygen bearing atmosphere in the range of 600° to 900°F (316° to 480°C) for about 30 to 60 minutes. The exact baking parameters must be determined for the annealing facility employed and the thickness of oxide layer desired.

Hiperco 50A

Standard Treatment

Anneal parts at 1575/1600°F (857/871°C) for 2 to 4 hours in dry hydrogen or vacuum and cool at 150/350°F (83/194°C) per hour until 600°F (316 °C) is reached, after which any cooling rate can be employed.

It is important to avoid any contamination of the finished fabricated parts during the heat treatment. All parts must be cleaned thoroughly to remove any surface contaminants prior to being placed in an air-tight retort.

A dry hydrogen atmosphere or a high vacuum is recommended to minimize oxide contamination of the parts during annealing. When hydrogen is employed, the entry dew point should be dryer than -60°F (-51 °C) and the exit dew point dryer than about -40°F (-40 °C) when the inside retort temperature is above 900°F (482°C).

Optional Treatments

  • Centerless Ground Bars Less Than 1.250″ (31.75 mm) Diameter

This duplex practice is only recommended for centerless ground bars in the size range given. Larger centerless ground bars, shapes, or hot rolled bars may be subject to cracking if quenched in this manner. This is a two-step treatment where the first step conditions the material for best machinability while the second develops optimum magnetic properties.

Preheat treat 2 to 3 foot lengths at 1850°F (1010°C) for about 30 minutes in air or protective atmosphere and quench bars in cold agitated water with their long axes in the vertical position. This preheat treatment develops a coarse acicular martensitic type structure which imparts ductility to the material and improves machining of the finish part.

The second part of the duplex treatment involves the employment of the standard treatment as described earlier. At no time should the temperature of the second treatment exceed 1600°F (871°C) because of the formation of a nonmagnetic austenitic phase which transforms upon cooling, thereby degrading magnetic properties due to transformation stresses.

  • For Products Produced from Any Size Bar

This practice can be applied to all parts produced from bar products, regardless of their size since no rapid quench practices are required. It provides improved capability magnetic properties on especially large cross sections compared to those of the standard heat treatment. Note, however, it is a lengthy process and, therefore, more expensive.

Heat the finish machined part in dry hydrogen or high vacuum to 1700°F (927°C) (heating rate is not critical) and hold at 1700°F (927°C) for three to four hours. Cool at 20°F (11°C) maximum per hour to 1350°F (732°C), then cool to 950°F (510°C) at 200°F (111°C) per hour. Cool at any rate thereafter.

Tools

The choice between high-speed steel and carbide tools depends largely on production quantities. When using carbide tools, surface speed feet/minute (SFPM) can be increased between 2 and 3 times over the high-speed suggestions. Feeds can be increased between 50 and 100%.
