| 20100190024 | SINTERED COPPER-BASED MATERIAL HAVING INCREASED GRAIN SIZE AND METHOD OF MAKING THE SAME - Disclosed are sintered copper-based materials and methods for forming the same having a larger grain size than materials formed through conventional methods. A metal powder having copper is compressed, pre-heated, and then sintered. Then, the density of the once sintered copper-based material is sized to increase density and subjected to a second sintering act. The sintered copper-based materials have a grain size of at least 50 μm. | 07-29-2010 |
