Die casting alloys represent roughly 12% of the zinc use worldwide. They are generally referred to as ZAMAK. It is an acronym for the German names of the metals of which the alloys are composed: Zink (Zn), Aluminium (Al), Magnesium (Mg) and Kupfer (Cu). The main alloys were developed by The New Jersey Zinc Company in 1929.
Our casting alloys
Today Zamak 3 (ZnAl4/ZL0400), Zamak 5 (ZnAl4Cu1/ZL0410) and Zamak 2 (ZnAl4Cu3/ZL0430) are the most commonly used die casting alloys.
REAZN can also supply Zamak 6 (ZnAl6Cu1/ZL0610), Zamak 8 (ZnAl8Cu1/ZL0810), Zamak 12 (ZnAl11Cu1/ZL1110), Zamak 27 (ZnAl27Cu2/ZL2720) which are suited for gravity casting applications.
Furthermore REAZN UK holds a license agreement for the manufacturing and selling of the EZAC™ high creep resistant alloy.
Fields of application
From building and furniture fittings to automotive components, zinc die castings positively impact our lives on a daily basis. A variety of casting processes are available to economically manufacture cast parts of whatever size and quantity required. Besides this, zinc die casting offers numerous advantages compared to other production methods: dimensional stability, precise casting tolerances, moderate casting temperatures, superior casting fluidity, reduced machining, thermal and electrical conductivity, faster production rates, extended tool life, well suited for coating and many more.
Examples of die cast parts: cam locks and fixing dowels, coffee machines, mirror frames, electrical connectors, zippers, bathroom fixtures (faucets and shower heads), safety razors, handles, locks, hinges and antenna holders in cars, golf clubs or wheel balancing weights.
