Each ingot weighs approximately 4lbs (3.9lbs-4.1lbs) and measures 1" x 2" x 8.5" with tapered sides. Zamak 3 is the de facto standard for the zamak series of zinc alloys; all other zinc alloys are compared to this alloy. Zamak 3 has the base composition for the zamak alloys (96% zinc, 4% aluminium). It has excellent castability and long term dimensional stability. More than 70% of all North American zinc die castings are made from Zamak 3. The melting temperature for Zamak 3 is approximately 725 degrees.
