The ADC12 aluminium is more often used as an alternative for the A380 aluminium for parts that are highly intricate.
The A380 Aluminium gives an excellent combination of machinability, heat transfer and easy casting together with other properties.
Zamak 7 has higher fluidity than the rest of the Zamak family alloys which makes it ideal for special hardware components.
The higher copper content gives Zamak 5 an improved strength but is less ductile than Zamak 3.
Zamak 4 brings an improvement to the mould sticking problems faced with Zamak 3.
Compared to the other members of the Zamak family of metals, Zamak 2 is the highest in terms of tensile strength, hardness and creep resistance.
