The development of high-tensile aluminium bronze alloys for marine propellers in Great Britain and the United States of America 1

Abstract

The excellent mechanical properties of the aluminium bronze alloys containing nickel, and their resistance to corrosion and erosion, have led to a remarkable increase in their use for many types of marine propellers with outstanding economic advantages. In this short paper the author describes the various technical and production factors involved and how these must be applied in practice if satisfactory results are to be obtained. The results of preliminary sea trials are given.
