摘要： Gold, copper, silver, palladium or aluminum and their alloys, but preferably gold or gold alloy, which may be in the form of a wire, has deposited thereon or contained within the wire, a material such as metals or metal alloys which diffuse into the gold or into the other listed metals. With the passage of time and exposure to temperature the deposited metal or metal alloy continues to diffuse into the gold forming intermetallics with the gold and thereby causing the resistivity of the gold to increase and causing the gold to become progressively more brittle until such time as the gold wire ruptures at a stress point. At a given temperature, the elapsed time until rupture takes place depends upon the metal or metal alloys deposited on or contained within the gold. Lead, indium, gallium, tin, bismuth and aluminum and the alloys of these metals diffuse into and form intermetallics with the gold. The time rate of embrittlement of the gold and the other soft metals listed is a function of the metal or metal alloy and the temperature. Gold wires so treated with the metal or metal alloys may be used as time temperature dependent fuses. For example such fuses may be useful for the protection of integrated circuits or systems of integrated circuits wherein the gold wires so treated are used as connections within the circuit or system.

摘要： A hardenable white gold alloy consists essentially of about 55-60 % gold, about 12-20% silver, about 8-15% copper, about 8-18% palladium, about 0.0-1.0% tin, zinc indium or cobalt, and, optionally, about 0.005-0.02% iridium and/or ruthenium, and also about 0.01-0.03 weight percent lithium. The alloy is nickel-free, but has a pleasing white color similar to that of nickel-containing white gold alloys. The alloy has a fine grain structure, a lower hardness in its annealed condition, but is capable of being hardened to an exceptional hardness value. The hardening procedure is reversible.

摘要： Rose-color and yellow-color gold alloys are formed from a gold-base alloy containing silver and copper. Mining these elements is usually highly detrimental to the environmental. Environmentally friendly alloys are obtained through the use of recycled elements and elements recovered from mines utilizing specific guidelines. Jewelry manufactured from these environmentally friendly alloys may be more receptive to a consumer, resulting in a competitive advantage.
