Polish project 664-class torpedo boat, with a hull of welded Hydronalium. Hydronalium is a family of aluminium-magnesium alloys.It is an alloy predominantly of aluminium, with between 1%-12% of magnesium as the primary alloying ingredient.
Section of a fish net on a salmon farm near Puerto Montt, Chile. The copper alloy woven mesh inside the frame has resisted biofouling whereas PVC (i.e., the frame around the mesh) is heavily fouled. Copper–zinc brass alloys are currently (2011) being deployed in commercial-scale aquaculture operations in Asia, South America and the US (Hawaii ...
