SU405964A1 - COPPER BASED ALLOY - Google Patents

Description

one

The invention relates to the search for copper-based alloys intended for the manufacture of 1. and shaped castings of a responsible and most important: molded parts of the shipboard;

Known alloy on the basis of copper, containing (in%):

Nickel7-20

AlyumshShy1-3,5

Iron0,01-2
