Document Type and Number:
Japanese Patent JP2001049366
Kind Code:
A
Abstract:
To provide a copper alloy having high strength and high electric conductivity and moreover excellent in heat resistance.
In a copper alloy contg., by weight, 0.1 to 0.4% Cr and 0.03 to 0.5% Mg, the content of Ti is controlled to 0.005 to 0.2%, and the atomic ratio between Ti and at least one kind of element selected from the group consisting of Fe, Co and Ni is controlled to the range of Ti/(Fe+Co+Ni)=0.7 to 3.0, by which its heat resitance can be increased.
