ZAMAK 5 ZL0410 has the same composition as zamak 3 with the addition of 1% copper in order to increase strength (by approximately 10%), hardness and corrosive resistance, but reduces ductility. It also has less dimensional accuracy Zamak 5 is more commonly used in Europe.
Coating capability is good. It has few errors of dimension. It is especially used in accessories and automobile industry.
•Zamak 5 is more readily plated, finished, and machined than Alloy 3 •When a measure of tensile performance is needed, ZL-5 castings are recommended. •It has a higher copper content than Zamak 3, which results in higher strength •It has less ductility (increased elongation) than Zamak 3 •Manufacturer must keep in mind that this reduction in ductility can affect formability during secondary operations such as bending, riveting, swaging, and crimping operations
