Background:

The high amount of zinc and tin present in naval brass inhibit dezincification properties which allow it to provide the alloy with an inherent resistance impingement by seawater at higher than normal temperatures. The alloy is also noted for its resistance to wear, fatigue, galling, and stress corrosion cracking. 

 

Usage:

Aircraft turnbuckle barrels, bolt, marine hardware, nuts, propeller shafts, rivets, valve stems, condenser plates, wielding rods.
