Fabrication Guidelines for C46400 Naval Brass<\/h3>\n

Dezincification Resistance:<\/strong>
\nThe defining feature of C46400 is the addition of Tin, which inhibits dezincification in saltwater. Tip:<\/strong> This makes it far superior to C360 for any submerged marine application.<\/p>\n

Machinability Rating:<\/strong>
\nC46400 has a machinability rating of 30% compared to C36000. Tip:<\/strong> It is tougher and generates more heat. We use sharp carbide tools and high-flow coolant to manage temperatures.<\/p>\n

Chip Breaking:<\/strong>
\nUnlike free-cutting brass, C46400 produces tougher, longer chips. Tip:<\/strong> We utilize specialized chip-breaking geometries to prevent chip wrapping on high-speed spindles.<\/p>\n

Hot Formability:<\/strong>
\nNaval brass has excellent hot-working properties. Tip:<\/strong> It is ideal for parts that are hot-forged and then precision CNC machined to final dimensions.<\/p>\n<\/div>\n

Primary Applications<\/h3>\n

Marine Hardware<\/strong>
\nPropeller shafts, decorative boat trim, turnbuckles, and hull fittings exposed to harsh saltwater spray.<\/p>\n

Fluid Control<\/strong>
\nPump shafts, valve stems, and condenser plates for heat exchangers in power plants and desalination units.<\/p>\n

Fastening Technology<\/strong>
\nHeavy-duty marine bolts, nuts, and rivets requiring high strength and resistance to marine environments.<\/p>\n

Industrial Machinery<\/strong>
\nBearings and bushings operating in wet or corrosive conditions where standard bronze might be too expensive.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
