Costs | CAD$3.24/kg | CAD$3.52/kg | CAD$9.16/kg | CAD$4.30/kg | CAD$3.42/kg |
Other Characteristics | Good forgeability, medium strength, can be hammer forged, seldom used | Excellent castability, good strength | Good forgeability, good strength, good ductility | High ductility and impact strength | Fine grained and pressure tight with good casting characteristics |
Typical Applications | Forgings and extruded bar, rod, shapes, structural sections, and tubing with moderate mechanical properties and high elongations | Usually used for die-casting | Extruded products and press forgings, with high strength and ductility High mechanical properties, problem with hot shortness, cracking, not good for sand/permanent mould castings, not weldable, has long fatigue life More costly than AZ series, zirconium is a strong grain refiner, it precipitates iron contaminates from alloy before casting More than 2.7% to 3% Zn, lose corrosion resistance, hot tearing is not a problem in HPDC | Usually used for die casting | Forgings and extruded bars, excellent retention of properties at elevated temperatures and good corrosion resistance |
