C61300 Aluminum Bronze is copper, alloyed with zinc, iron and aluminum. C613 offers levels of corrosion and high velocity seawater erosion resistance similar to C71500 70/30 Copper Nickel but with higher strength and resistance to fatigue.
Aluminum Bronze 61300 is primarily available in wrought plate form and is used most often in sea water service, steam condensers, oil coolers and other heat exchangers operating on sea water. Tubesheets made from C613 Aluminum Bronze are often paired with copper-nickel tubes in sea water cooled condensers and heat exchangers.
