Applications:

• Used on parts where high degree of corrosion resistance to seawater is required.
• The copper-zinc allow with tin, combines good mechanical strength with the ability to resist corrosion by the sea and many natural waters.
• This allow is extensively used in the manufacture of heat exchanges of tube sheets and plates, and in the extruded form for propeller shafting, valves, spindles and general marine hardware.

Profiles Available:

• Round Bar / Rod
• Flat Bar / Plate
