Publication number: 20040159379Abstract: 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 850° 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.Type: ApplicationFiled: February 19, 2004Publication date: August 19, 2004Inventors: Andreas Bogel, Jorg Seeger, Hans-Achim Kuhn, John F.

Patent number: 6632300Abstract: A copper alloy having improved stress relaxation resistance is formed from a copper base alloy that consists, by weight, essentially of 1.8%-3.0% iron, 0.01%-1.0% zinc, 0.001 %-0.25% phosphorus, 0.1 %-0.35% magnesium and the balance is copper and unavoidable impurities. When compared to other copper base alloys that include iron, zinc and phosphorous, the disclosed alloy has improved resistance to stress relaxation. In addition, directionality of stress relaxation resistance (where stress relaxation resistance is typically poorer in a transverse strip direction relative to a longitudinal strip direction for a copper alloy that is strengthened by cold rolling) is reduced to being nearly equivalent, regardless of strip direction. The alloy is particularly useful for electronic applications, such as being formed into an electrical connectors.Type: GrantFiled: June 12, 2001Date of Patent: October 14, 2003Assignee: Olin CorporationInventors: John F. Breedis, Dennis R. Brauer, Peter W. Robinson

Publication number: 20030029532Abstract: 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.Type: ApplicationFiled: May 24, 2001Publication date: February 13, 2003Applicant: OLIN CORPORATIONInventors: John F.

Patent number: 6471792Abstract: 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 125° C. to 150° C., for significantly longer times than other brass alloys of comparable strength.Type: GrantFiled: October 29, 1999Date of Patent: October 29, 2002Assignee: Olin CorporationInventors: John F.

Patent number: 6132528Abstract: There is provided a tin brass alloy having a grain structure that is refined by the addition of controlled amounts of both zinc and iron. Direct chill cast alloys containing from 1% to 4%, by weight of tin, from 0.8% to 4% of iron, from an amount effective to enhance iron initiated grain refinement to 35% of zinc and the remainder copper and inevitable impurities are readily hot worked.

Patent number: 5980656Abstract: A copper alloy achieves high electrical conductivity, in excess of 70% IACS; high strength, ultimate tensile strength in excess of 75 ksi; good surface cosmetics; and good stampability, above 25% break, by controlled additions of magnesium, iron and phosphorous. There is a critical iron content to achieve both good stampability and high electrical conductivity and a critical phosphorous content to achieve high strength and relatively small metal phosphide particles. There is further, a critical relationship between the amount of iron and phosphorous. An additions of magnesium, in amounts of more than 0.03%, broadens the effective ratio of iron to phosphorous, widening the composition box of the alloys of the invention.Type: GrantFiled: July 22, 1997Date of Patent: November 9, 1999Assignee: Olin CorporationInventors: William L. Brenneman, John F. Breedis

Patent number: 5882442Abstract: There is provided a phosphor bronze alloy having a grain structure that is refined by the addition of a controlled amount of iron. Direct chill cast alloys containing from 1.5% to 2.5%, by weight tin, from 1.65% to 2.65% iron, from 0.03% to 0.35% phosphorous and the remainder copper and inevitable impurities have an as-cast average crystalline grain size of less than 100 microns and are readily hot worked. When the iron content is too low, the average crystalline grain size increases and the alloy cracks during hot working. When the iron content is too high, iron stringers form, detrimentally impacting both the appearance and properties of a wrought strip.Type: GrantFiled: February 9, 1996Date of Patent: March 16, 1999Assignee: Olin CorporationInventors: Ronald N.

Patent number: 5637160Abstract: There is provided a machinable .alpha.+.beta. brass containing bismuth and phosphorous.

Patent number: 5472796Abstract: There is provided a metallic composite useful for coinage. The core is formed from a copper alloy that contains between 50% and 99.0% copper, has a room temperature electrical conductivity in excess of 25% IACS an initial yield strength in excess of 10,000 psi and a dynamic softening response onset at a temperature in the range of 200.degree. C.-400.degree. C. The cladding layers have an initial yield strength more than that of the core and a gold color.
