Project Description

ZA-7 / Zamak 7

Zamak 7

Zamak 7 has less magnesium than zamak 3 to increase fluidity and ductility, which is especially useful when casting thin wall components.

zamak 7ZA-7ZA-7 / Zamak 7Zamak 7 / ZA-7

Zamak 7 proved casting fluidity, ductility and surface finish.
Higher fluidity is sometimes desirable especially on components with intricate detail, however it does present special casting considerations

Zamak 7 is mostly used for special hardware applications, or when castings require extra formability during subsequent assembly operations such as crimping or staking. Its higher fluidity also allows thinner walls to be cast

Zamak 7 exhibits excellent damping capacity and vibration attenuation in comparison with aluminum die casting alloys.
The high ductility exhibited by this alloy also has an impact on processing, but mainly in secondary operations for flash removal and trimming
Its higher fluidity also allows thinner walls to be cast
