ABSTRACT:
The present invention relates to an iron-nickel alloy containing from about 30% to about 60% nickel, from about 0.001% to about 0.15% nitrogen, at least one element selected from the group consisting of from about 1% to about 10% molybdenum and from about 0.001% to about 2% aluminum and the balance essentially iron. The alloys demonstrate improved resistance to intermetallic compound formation, improved glass to metal sealing properties, and improved wirebonding performance. The alloys of the present invention have particular utility as a lead frame material for semiconductor packages.
