Naval brass adds tin to the copper-zinc base, dramatically improving resistance to dezincification and seawater corrosion. MEI manufactures naval brass sheets and plates in both IS 291 grades for marine, shipbuilding, and heat-transfer applications where standard brass would deteriorate \u2014 combining the strength and machinability of brass with proven saltwater durability.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
