  • COPPER-NICKEL-SILICON ALLOYS WITH HIGH STRENGTH AND HIGH ELECTRICAL CONDUCTIVITY
    Publication number: 20250197972
    Abstract: A copper alloy that does not contain beryllium and has a 0.2% offset yield strength of at least 80 ksi and an electrical conductivity of at least 48% IACS is disclosed. The copper alloy contains nickel, silicon, chromium, manganese, zirconium, and balance copper. The alloy is prepared by cold working, solution annealing, and aging. The alloy can be used, for example, as a heat sink.

  • Nickel beryllium alloy compositions
    Patent number: 9334551
    Abstract: Disclosed herein are nickel beryllium alloys having improved corrosion and hardness characteristics relative to known nickel beryllium alloys. The alloys have a chemical composition with about 1.5% to 5% beryllium (Be) by weight, about 0.5% to 7% niobium (Nb) by weight; and nickel (Ni). Up to about 5 wt % chromium (Cr) may also be included. The alloys display improved hardness and corrosion resistance properties.
