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. It gains strength and hardness after ageing for the long term. Some of its outstanding casting qualities are damping capacity and vibration attenuation. However, it gets brittle and shrinks with time. It is used in the production of short-run injection moulding dies.
