Mike,

AFAIK, duralium is the same as duralumin: "an alloy of aluminum (over 90%) with copper (about 4%), magnesium (0.5%–1%), and manganese (less than 1%). Before a final heat treatment the alloy is ductile and malleable; after heat treatment a reaction between the aluminum and magnesium produces increased hardness and tensile strength. Because of its lightness and other desirable physical properties, duralumin is widely used in the aircraft industry."

HTH,
