Alloys

Pure aluminum has good corrosion resistance and working and forming properties but poor machining char­acteristics and low mechanical strength. By adding other elements to aluminum, its strength and machining char­acteristics can be improved. Such a combination of two or more elements, at least one of which is metallic, is cal­led an alloy and the predominant metal in the system is referred to as the base metal.

Silicon, copper, zinc and magnesium are common al­loying elements and are often added to aluminum in sub­stantial proportions. Iron, manganese, nickel, chromium, titanium, antimony, cadmium, cerium, lithium, beryllium and molybdenum are also added in smaller proportions with various beneficial effects.

Titanium, tungsten, cerium and molybdenum all con­tribute to grain refinement of cast aluminum. Manganese and antimony are often added to improve corrosion resist­ance. Cobalt and nickel affect strength and workability while cadmium and tin increase hardness in heat treatable alloys.

The market penetration of ZA alloys has been aided by the fact that traditional high volume foundry metals have significant shortcomings that detract from their inherent advantages:

cast iron has high energy and machining costs, protec­tive finishes are nearly always required and there are in­dustry environmental problems;

bronze has high material and energy costs and the environmental problem of lead for many important alloys;

aluminum has limitations in strength, bearing proper­ties and finishing along with moderately high energy costs. Of course, each of these classic materials does have distinct advantages in given applications.

In contrast, the zinc casting alloys have advantages that are highly attractive to foundries:

excellent casting properties;

low energy consumption;

pollution free melting and casting;

excellent machinability;

lower material cost and density than bronze.
