Abstract
Copper base alloys having improved rupture properties and improved hot rolling performance consisting of from 2 to 9.5% aluminum, preferably also from 0.001 to 3.0% silicon, a grain refining element, preferably cobalt in an amount from 0.001 to 5.0%, from 0.001 to 0.5% of a material selected from the group consisting of a material of the lanthanide series of the Periodic Table and mixtures thereof, and the balance essentially copper.

A copper base alloy having improved high temperature rupture properties consisting of from 2 to 9.5% aluminum, a grain refining element selected from the group consisting of iron from 0.001 to 5.0%, chromium from 0.001 to 1%, zirconium from 0.001 to 1.0%, cobalt from 0.001 to 5.0%, and mixtures of these elements, from 0.01 to 0.5% of a material selected from the group consisting of a material of the lanthanide series of the Periodic Table and mixtures thereof, balance copper.
A copper base alloy having improved high temperature rupture properties consisting of from 2 to 9.5% aluminum, from 0.001 to 3% silicon, less than 1% zinc, a grain refining element selected from the group consisting of iron from 0.001 to 5.0%, chromium from 0.001 to 1%, zirconium from 0.001 to 1%, cobalt from 0.001 to 5.0%, and mixtures of these elements, from 0.001 to 0.5% of a material selected from the group consisting of a material of the lanthanide series of the Periodic Table and mixtures thereof, balance copper.
