C4640 sheet
Naval Brass is used extensively in marine construction due to its high corrosion resistance to seawater It is known for its good strength, good rigidity/hardness and resistance to wear, fatigue, galling and stress cracking. Also recognized for superior tensile strength, higher yield strength, good elongation, excellent thermal conductivity, good capacity for being cold worked, excellent capacity for being hot formed and excellent soldering and brazing
