| Number | Title | Issue Date |
| 7544259 | Copper alloy, copper alloy producing method, copper complex material, and copper complex material producing method An element such as Cr is caused to dissolve sufficiently in a base-material metal (Cu) in a solid solution state at a high temperature and a material in a supersaturated condition is obtained by performing quenching. After that, a strain is applied to this material ... | 06/09/2009 |
| 6679956 | Process for making copper-tin-zinc alloys A process for making a copper base alloy comprises the steps of casting a copper base alloy containing tin, zinc, iron and phosphorous and forming phosphide particles uniformly distributed throughout the matrix. The forming step comprises homogenizing the... | 01/20/2004 |
| 6190468 | Metamorphic processing of alloys and products thereof In accordance with one aspect of the present invention is the metamorphic processing of a beryllium-copper alloy. The alloy is (i) thermodynamically treated for greater than about 10 hours at a temperature generally within a range of 900° to 1500° F., (... | 02/20/2001 |
| 6136104 | Copper alloy for terminals and connectors and method for making same A copper alloy which is adapted for use as terminals and connectors, which comprises from 0.1 wt % to less than 0.5 wt % of Ni, from larger than 1.0 wt % to less than 2.5 wt % of Sn, from larger than 1.0 wt % to 15 wt % of Zn, and further comprises from a... | 10/24/2000 |
| 5798008 | Method for producing copper alloy materials for molds for continuous steel casting, and molds made of the materials A method for producing copper alloy materials for molds for continuous steel casting and molds as produced by the method.
