Atoms of an element such as Cr is made to form a solid solution in a matrix metal (Cu) at a high temperature and quenched to produce an oversaturated material. This material is strained and aged at a low temperature simultaneously with the straining or after the straining. Thus a copper alloy having preferable characteristics as an electrode material, for example, a hardness of 30 (HRB) or more, a conductivity of 85 (IACS%) or more, and a thermal conductivity of 350 (W/(m.cndot.K)) or more is produced.
Des atomes d'un élément tel que Cr sont mis en oeuvre pour former une solution solide dans un métal matriciel (Cu) à une haute température et trempés afin de produire un matériau sursaturé. Ce matériau est écroui et vieilli à basse température simultanément à l'écrouissage ou après l'écrouissage. Ainsi est produit un alliage de cuivre ayant des caractéristiques avantageuses en tant que matériau d'électrode, par exemple, une dureté de 30 (HRB) ou plus, une conductivité de 85 (IACS%) ou d'avantage, et une conductibilité thermique de 350 (W/(m.K)) ou plus.
