Copper Alloys Dealers

We are offering copper-nickel alloys (often referred to as cupro-nickels) offer moderate to high strength and excellent resistance to various waters, including seawater and form a protective surface film in such conditions. In addition they provide good anti-fouling properties and weldability. the precipitation hardenable copper nickels (def stan 02-835 and ultibronã¢â€â¢-nb) possess high strength and are used as an alternative to the 9010 and 7030 alloys and other copper alloys such as nickel aluminium bronze in marine applications. Other useful attributes include low magnetic permeability, impervious to hydrogen embrittlement, no loss of impact strength down to minus 196ã‚â°c and good jet impingement resistance. applications for 9010 and 7030 alloys mainly involve tubes and tube plates in heat exchangers, including desalination and seawater piping systems. 7030 alloy is also used for hose couplings, mechanical seals and pump shafts. Applications for the high strength cupro-nickels are varied and cover subsea bolting in oil & gas to hydraulic connectors and valve stems. usage in naval vessels is widespread, for example, for bolting, propeller shafts, sonar components and weapons handling equipment. Copper-nickel alloys are also finding new applications replacing beryllium-copper alloys due to environmental difficulties in their manufacture.
