Properties of wrought aluminum and aluminum alloys

The properties of these shades depend essentially on :

• impurity content (iron and silicon in particular);

• any minor additions ;

• hardening levels achieved by work-hardening or softening levels obtained by restoration and annealing.

Generally speaking, unalloyed aluminium has :

• excellent plastic deformability;

• relatively low mechanical strength;

• excellent resistance to chemical agents and different atmospheres;

• good welding, brazing and anodizing skills;...
