Filed:

Oct 29, 1999

Appl. No.:

09/429871

Inventors:

John F. Breedis - Trumbull CT
Ronald N. Caron - Branford CT
Carl L. Deppisch - Hamden CT

Assignee:

Olin Corporation - East Alton IL

International Classification:

C22C 902

US Classification:

148433, 420472

Abstract:

An alpha brass (copper/zinc alloy with less than 39%, by weight, of zinc) stock alloy has controlled additions of nickel, tin and phosphorous. The combination of nickel and tin increase resistance of the alloy to elevated temperature stress relaxation. As a result, spring contacts formed from alloys of the invention maintain a higher percentage of initially imposed stress at elevated temperatures, in the range of 125Â C. to 150Â C. , for significantly longer times than other brass alloys of comparable strength.

International Classification:

C22C 900

US Classification:

148432, 420473, 420490, 148433

Abstract:

A copper alloy that consists essentially of, by weight, from 0. 15% to 0. 7% of chromium, from 0. 005% to 0. 3% of silver, from 0. 01% to 0. 15% of titanium, from 0. 01% to 0. 10% of silicon, up to 0. 2% of iron, up to 0. 5% of tin, and the balance copper and inevitable impurities has high strength, a yield strength in excess of 80 ksi, and high electrical conductivity, in excess of 80% IACS. The alloy further has substantially isotropic bend characteristics when the processing route includes a solution heat anneal above 850Â C. and subsequent cold rolling into sheet, strip or foil interspersed by bell annealing. As a result, the alloy is particularly suited for forming into box-type electrical connectors for both automotive or multimedia applications. The alloy is also suitable for forming into a rod, wire or section.

US Classification:

148/554000, 420/472000, 420/473000

Abstract:

A high copper alloy with good resistance to stress relaxation at temperatures of up to at least 150 C., consists, by weight, essentially of from 0.8% to 3% of iron, from 0.3% to 2% of nickel, from 0.6% to 1.4% of tin, from 0.005% to 0.35% phosphorous and the remainder copper and inevitable impurities. The alloy has an electrical conductivity in excess of 40% IACS and a yield strength of 70 ksi or higher at final gauge following a relief anneal. Over 75% of an imposed stress remains after exposure to 150 C. for 3000 hours. The combination of good electrical conductivity, high strength and high stress relaxation resistance makes the alloys particularly suitable for under the hood automotive electrical connectors.

Assignee:

Olin Corporation - New Haven CT

International Classification:

C22F 108

US Classification:

148 2

Abstract:

A multipurpose copper base alloy having an improved combination of ultimate tensile strength and electrical conductivity. The alloy can be tailored for applications such as in connectors or leadframes by processing. The alloy may be processed to provide improved bend formability at some sacrifice in strength. The alloy in the stabilized condition shows surprising improvement in stress relaxation resistance. The alloy comprises a Cu-Ni-Si alloy to which about 0. 05 to about 0. 45% by weight magnesium is added.
