ZAMAK 5（ZNAL4CU1，ZPO410）

Zamak 5 castings are marginally stronger and harder than Zamak 3. However, these improvements are tempered with a reduction in ductility which can affect formability during secondary bending, riveting, swaging or crimping operations. Zamak 5 contains an addition of 1% copper which accounts for these property changes. The zinc die casting alloy is widely die cast in Europe and does exhibit excellent castability characteristics, as well as, improved creep performance over Zamak 3. Because of Zamak 3's wide availability, material specifiers often strengthen components by design modifications instead of using Zamak 5. However, when an extra measure of tensile performance is needed, Zamak 5 alloy castings are recommended. The alloy is readily plated, finished and machined, comparable to Zamak 3 alloy.

Performance feature：

This product meets the standards of China, the United States and the European Union;Comply with ROHS, EN71Part3, EN1811, CPSIA and other requirements;
Low remelting temperature, less slag content, and fine internal crystallization;
Good physical and mechanical properties, castability, dimensional stability and creep resistance.

Method of application

Bake and dry before use. Do not stir or dredge when feeding.The scum above the molten liquid is stirred calmly with a slag rake to collect it and remove it;
The nozzle material according to the ratio of 25%-30% input, no need to slag;
The best die casting temperature: 420℃-435℃, the best mold temperature: 210℃-230℃.The upper limit of die-casting temperature is recommended for thin-walled parts and complex parts, and the lower limit is recommended for thick-walled parts and simple parts.
The following phenomena may exist in the use process: there is a thin oil film on the surface of the alloy liquid, and there will be a small amount of black film, which is a normal phenomenon.
