Copper Nickel Made Round Bar has good resistant to seawater, brine water, organic compounds, salts, diluted non-oxidizing acids. The Bar has good strength and ensures good resistance to various waters, including seawater and form a protective surface film in such conditions The Bar has low magnetic permeability, imperviousness to hydrogen embrittlement, no loss of impact strength down to minus 196 ° c and good jet impingement resistance. The Bar can be used for hose couplings, mechanical seals and pump shafts. The Bar can be used for bolting, propeller shafts, sonar components and weapons handling equipment and finds application in marine engineering due the good strength and ability to be hot and cold worked. The Copper Nickel Made Round Bar is easily welded and exhibits good resistance to stress corrosion.
