General zinc alloy die casting materials are Zamak 3# and Zamak 5#, in different countries, the License Name is also different. Like Germany, the zinc alloy license numbers are GD-ZnAl4Cu1&GD-ZnAl4.

The casting performance and size of Zamak 3# are relatively stable in die-casting, making and more than 70% of zinc alloy die-casting products use Zamak 3#. Zamak 3# can do electroplating, spraying paint and chromizing surface treatment. Widely used in electronic communication, instrumentation and other mechanical parts; It also been used for toys, accessories, tableware, locks and other advanced hardware.
Zamak 5# has higher hardness and strength than Zamak 3#. The characteristic change of Zamak 5# is due to the addition of 1% copper, so Zamak 5# has excellent casting property, better deformation performance when heated at high temperature than 3#, which can be used for electroplating, cutting and general surface treatment, and is suitable for sports equipment and industrial accessories.
