Improved corrosion resistance; bolts, fittings etc. in marine use. Low lead content for use where environmental aspects may be a concern.
Full alloy description:
A.W. Fraser Alloy 464 is an standard American type naval brass conforming to the requirements of ASTM B21 alloy C46400.
464 has been developed, with the deliberate addition of tin, to give improved resistance to corrosion and dezincification, particularly in salt water, and moderate ductility.
The composition of A.W. Fraser alloy 464 is strict ly controlled as are the extrusion and finishing op erations to achieve a constant standard of quality, properties and structure. All extrusions are manufactured from continuous cast billet stock ensuring uniform dispersion of tin particles and freedom from porosity.
Alloy 464 is susceptible to dezincification under certain conditions and is classified a category III alloy.
Machinability Rating: 30
SAE Grade: 73 / J461 / J463
