Allegheny technologies incorporated [ati] is one of the world`s largest and most diversified producers of specialty metals. Ati produces a wide assortment of nickel-based super alloys and electronic alloys are one of them which has the characteristics of soft magnetism, controlled expansion and thermal expansion. The most common applications are attachment of metallic parts to the internal of tv and cathode ray tubes, and also certain lamp bulb bases. Salient features of different models of electronic alloys:
Al 36 - controlled expansion: liquefied gas storage, bimetallic strips for thermometers, lng, tv aperture masks, composite wing molds
Al 42 - controlled expansion: lead frames, color tb electron guns, glass-metal and ceramic-metal seals, transistors
Al 4750 - soft magnetic: magnetic relay parts, magnetic shielding, pole pieces, specialty motor stators and rotors, electric transformers, and magnetic amplifiers
Moly permalloy - soft magnetic: cores and relay components for high sensitivity ground fault circuit breakers, magnetic shields, and electric transformers.
