Abstract
New and improved copper base alloys, characterized by a combination of high electrical conductivity and excellent strength properties, consisting essentially of 0.8- 5% by weight of titanium as a first component, a portion of which may be a like element such as zirconium or hafnium or both, 1.2- 5% by weight of antimony as a second component, part of which may be replaced by one or more of the elements arsenic, phosphorus, silicon, germanium and tin, with the atomic ratio of the total titanium and like elements, to antimony and like elements, being not more than 10% above 5:3, and the balance essentially copper.
Claims5
A high conductivity and high strength copper base alloy consisting essentially of 0.8 to 5% by weight titanium as a first component, 1.2 to 5% by weight of a second component selected from the group consisting of antimony, phosphorus, silicon, arsenic, germanium, tin and mixtures thereof, balance copper, wherein the first and second components are present at an atomic ratio of not more than 10% above 5 atoms of said first component per 3 atoms of said second component.
