Alloy 5005 Aluminum Plate Sheet

    Alloy 5005 aluminum plate sheet is a medium strength alloy with good resistance to atmospheric corrosion and very good weldability that is highly suitable for decorative anodising. Please note that alloy 5005 aluminum plate sheet is suitable for anodizing, streaks can occur, if the finish you are seeking is critical please specify “special anodising quality” at time of order.

 
    Alloy 5005 aluminum plate sheet is a non-heat-treatable 0.8% magnesium alloy commonly available in flat rolled coil, sheet and plate from a wide range of producing mills. The 5000-series magnesium alloys have a high strengths because of the magnesium addition; 5005 has only a very small addition of magnesium so is the least
strength of these series of alloys. The alloy is hardenable to a significant degree by cold working, enabling a series of “H” tempers but again these do not achieve the high strengths of corresponding tempers in other alloys such as 5052 or 5083.

 
    The most common tempers for 5005 aluminum plate sheet are:
H34 stabilised - A low temperature thermal treatment or heat introduced during manufacture which stabilised the mechanical properties and relieves residual internal stress, plus usually improves ductility
 
    The alloy is also produced as stranded conductor, drawn seamless tube, wire and bar, available on indent from Atlas.
 
Corrosion Resistance
Excellent in a wide range of atmospheric environments, in architectural applications. The magnesium content is low enough that it does not suffer from the stress corrosion cracking that can affect alloys with more than about 3½% Mg, such as 5083.
 
Heat Treatment
Alloy 5005 aluminum plate sheet is not hardenable by heat treatment. It can be significantly hardened by cold work (eg by cold rolling) and various “H” tempers are produced – most commonly H32 (¼ Hard) and H34 (½ Hard) – as well as the soft annealed Temper O condition. The alloy spontaneously age-softens at room temperature immediately after cold work but will eventually reach a stable condition; all flat rolled mill products are supplied with stable properties. This is usually achieved by a stabilisation thermal treatment, either a low temperature thermal treatment or as a result of heat introduced during rolling, which results in the H3x tempers. H2x tempers are more
severely strain hardened and then partially annealed, again to quickly reach the required stable temper properties. To soften Alloy 5005 it can be annealed by heating to 345°C, hold until uniform temperature then cool; the rate of cooling is not important.

 
Anodising
All aluminium alloys can be anodised to improve corrosion resistance, but decorative anodising is only carried out on a few alloys. The most commonly decoratively anodised non-heat-treatable alloy is 5005. It is produced as a special “anodising quality” (AQ) but Atlas does not stock this product. It is most common and usually successful for general purpose quality (non-AQ) to be anodised; this can however result in some visually inconsistent anodising outcomes and in severe cases in “tiger stripe” appearance. It is always recommended that anodising performance be tested by trialling a piece from a batch of sheet.
AQ sheets can be sourced on indent if required for critical applications. 
When anodised, film on 5005 is clearer and lighter than on 3003 and gives better colour match with 6063 architectural extrusions.
 
Welding
Excellent weldability by all standard methods; gas, electric and resistance welding. GMAW and GTAW are preferred and widely used. Filler alloys are usually 4043 although other alloys are possible. Welding of strain hardened tempers will reduce strengths in the heat affected zones.
 
Machining
Machinability is poor, with the harder tempers such as H34 and above being somewhat easier to machine.
