1 Aluminium AlloyData Sheet6063 Revised October 2013 Page 1 of , silicon alloy offering goodmechanical properties commonly available in awide range of extruded sections. Its readyextrudability enables thin walled and intricatehollow shapes to be produced: flats, angles,channels and hollow circular and squaresections are all standard profiles. 6063respondswelltopolishing,chemicalbrig htening, anodising and alloys to 6063 are 6061, 6005 and6005A, all of which are possible ResistanceExcellent in a wide range of atmosphericenvironments and it is also acceptable in manymarine environments. This alloy is magnesium content is low enough that itdoes not suffer from the stress corrosioncracking that can affect alloys with more thanabout 3 % Mg, such as TreatmentAlloy 6063 is hardenable by solution treating(522 C followed by water quenching) andageing (precipitation) heat treatment.

2 It ismost commonly supplied in the aged T5 or soften Alloy 6063 back to Temper O it canbe annealed by heating to 415 C, holding for 2 3 hours then cooling; the rate of coolingshould be about 30 C per hour down to 260 rate of cooling below that is not to 345 C followed by uncontrolledcooling may be used to remove the effects ofcold work, or to partially remove the effects ofheat weldability by all standard methods;gas, electric and resistance welding. GMAWand GTAW are preferred and widely used for welding exposed surfacesthat will be anodised for decorative purposes is5356. Alloy 4043 filler may be used for otherapplications. The strength in the heat affectedzone may be reduced by over-aging. Otherfiller alloys may also be machinability in all the commonlyavailable ApplicationsHandrailing, furniture and various extrudedarchitectural profiles such as window AlloyData Sheet6063 Revised October 2013 Page 2 of PropertiesThese properties are specified for extruded product (bar, rod, solid and hollow shapes) inAS/NZS 1866:1997.
