C46400 Naval Brass, Uninhibited Bronze Alloy

C46400 uninhibited naval brass earned its name because people trust it in marine applications. Because tin is added to the alloy, it has improved strength and resistance to dezincification. It is a wrought alloy with good corrosion, wear, fatigue, and galling resistance.

C46400 is used in several industries and applications, including builders' hardware, electrical, fasteners, industrial, marine, and plumbing. Common applications include:

  • Naval Brass Bolts
  • Naval Brass Decorative Fittings
  • Naval Brass Lock Pins
  • Naval Brass Marine Hardware
  • Naval Brass Nuts
  • Naval Brass Propeller Shafts
  • Naval Brass Rivets
  • Naval Brass Turnbuckles

Diversified Bronze has solid and cored bars and plates available. Talk with a representative about your specific needs.
