Abstract
The present invention relates to iron-nickel alloys having improved glass sealing properties. Alloys of the present invention contain from about 30% to about 60% nickel, from about 0.5% to about 3% silicon, from about 0.5% to about 3.5% aluminum and the balance essentially iron. Preferably, the alloys have a total aluminum plus silicon content of less than about 4%. The alloys of the present invention have particular utility in electronic and electrical applications. For example, they may be used as a lead frame or a similar component in a semiconductor package.
