Abstract

1332479 Alloy nozzle for refining metal melts BERRY METAL CO 11 Nov 1970 [18 Nov 1969] 53725/70 Heading C7A An internally-cooled nozzle for directional injection of a refining agent into a molten metal bath is made from an alloy comprising:- Al 0À005-0À3% and Zr 0À005-0À03% the balance, apart from impurities such as Cr and Fe, being de-oxidized Cu. The alloy is made under inert gas or vacuum conditions.
