Naval Brass C46400

Specs: ASTM-B-171, QQ-B-639, ASTM-B-21, ASTM B124, QQ-B-637, AMS 4611
UNS#: C46400

Naval Brass C46400 is an alloy that consists primarily of Copper and Zinc, with up to 1% Tin. Naval brass 46400 provides a high degree of corrosion resistance to seawater at even higher than normal temperatures, while also assuring greater strength and rigidity. It possesses excellent capacity for hot working and adapts well for hot forging and pressing. This Naval Brass also lends itself to drawing, forming, bending, and heading. It is readily soldered, brazed, and welded.

 

Wieland Diversifed maintains one of the most comprehensive stocking programs of Naval Brass in the country, which includes round bar and hexagon bar sizes.

Details

Naval Brass C46400 (CuZn39Sn1) is a 60/40 alpha beta brass with the addition of 1% tin, which aids the alloy to resist dezincification in seawater corrosion applications.

 

The tin also gives additional strength to the alloy without significantly reducing the ductility associated with 60/40 brass.

 

Naval Brass C46400 has excellent hot working characteristics that enable the alloy to be close die forged into valve bodies and other complex-shaped components and can be cold worked to increase the strength.

 

This enables the alloy to be supplied in the half-hard or fully hard condition.

 

Additionally, Naval Brass C46400 is used in the form of a flat product for condenser endplates in water treatment and desalination plants.

 

C46400 can be joined by soldering, brazing, and oxyacetylene welding, and has a machinability rating of 30% compared with free machining brass at 100%.

Available shapes – round, hex, rectangular and square
