A new high fluidity zinc die cast alloy was developed at Teck Metals' Product Technology Centre. This hot chamber die cast alloy is based on the commonly used ZAMAK alloys but possesses up to 40% better fluidity. Industrial trials and evaluations have confirmed the excellent fluidity of the alloy as well as the easy use and adoption of the alloy. Tests have shown the alloy has comparable physical, mechanical and corrosion properties as Alloy 3 and 7. The alloy is best suited to be used for casting parts with section thickness less than 0.45 mm. It can also be used for casting parts that are difficult to fill or have high surface finish requirement.
