What is 5005 aluminum alloy?
Aluminium alloy 5005 contains 0.8% magnesium, magnesium and aluminum alloy commonly available in flat rolled coil, 5005 aluminum sheet and plate from a wide range of producing mills.
It has medium strength, good weldability, and good corrosion resistance in marine atmospheres.Aluminum 5005 alloy metal is a lean aluminum magnesium alloy with low density and excellent thermal conductivity. Tempers H116 and H321 can be used in fresh and salt water.
5005 has only a very small addition of magnesium so is the least strength of 5000 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.
5005 aluminium alloy temper
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;
5005 alloy is the most commonly used grade of aluminium in aluminium sheet and aluminium plate form.

Almost all aluminum and aluminum alloy varieties are used on ships. Currently used most is the 5XXX series. Marine grade aluminium 5005 is one of them. The aluminum varieties are: aluminum thick plate, aluminum plate, aluminum sheet, aluminum strip, aluminum foil, aluminum tube and so on.
5005 aluminum sheet/plate chemical composition
Chemical Composition conforms to Chinese, American and European standard specification
5005 aluminum sheet belongs to 5-series Al-Mg alloy, but the content of the main alloy Mg is less than that of other 5-series alloy sheets, so it has a slightly higher corrosion resistance than the 3-series alloy. Among them, the performance of 5005 aluminum alloy is similar to that of 3 series 3003 aluminum alloy, with moderate strength, good fusion, processing and formability.
Physical properties of 1050 aluminum sheet
Heat Treatment of Aluminium Alloy 5005
Aluminium 5005 is annealed at 345°C, time at temperature and cooling rate are unimportant. Stress relief is rarely required, but can be carried out at about 220°C. If loss of strength is of concern, stress relief tests should be conducted.

Indicative minimum bend radii for 90° cold forming for various thickness, t mm
Recommended minimum bending radius for sheet of thickness given, at 90° to the rolling direction.
These values are recommended but are not guaranteed; the minimum possible bend radius will depend on the type of bending equipment and on the tooling and its condition.
Welding Aluminium Alloy 5005
It can attain moderate to high strength by cold working, and has relatively high welded strength, workability, and corrosion resistance compared to other aluminum alloy families. Aluminum 5005 is readily machinable, and can be welded using TIG and MIG methods. Aluminium must be very dry & clean to avoid contamination & porosity of the weld. Filler metals 1100, 4043 or 4047 are used.
Applications of Aluminium Alloy 5005
Due to its many benefits, Aluminum 5005 is in use in a wide variety of applications and industries including:
- Roofing & siding materials
- Chemical & food equipment
- Storage tanks
- Home appliances
- Sheet-metal work
- Electric conductors
- High Strength foil
- HVAC equipment
Marine grade aluminium 5005 is widely used in ship shells. The form of the hull structure can be divided into three types: horizontal skeleton type, vertical skeleton type and mixed skeleton type. Aluminum alloy small fishing boats, the main end structure of large ships is usually horizontal skeleton structure. The aluminum alloy materials used on the hull are mainly plates, profiles and wide-width extruded slabs.
5005 Aluminum Sheet for Curtain Wall
5005 aluminum sheet can be used as high-end wide-format curtain wall material, which has the advantage of excellent anodic oxidation effect compared with the commonly used 3003 aluminum sheet for curtain wall. In addition, 5005 aluminum alloy is light, only one fifth of the marble, one third of the glass curtain wall, and can be perfectly combined with the glass and stone curtain wall material, presenting a fashion, trend, unique modern architectural style. It is worth mentioning that, the cost-effective price, as well as the low maintenance cost in the later period, make the architects more favor to the 5005 aluminum sheet!
5005 Aluminum Sheet Other Usages
Besides, 5005 aluminum sheet is also commonly used for building decoration parts, vehicle interior materials, instrument panel, oxidizing materials, cooking utensils, conductors and other manufacturing.
anodized 5005 aluminum sheet
5005 aluminum alloy metal is formulated for a decorative architectural anodized finish. It allows for a more uniform and attractive anodized finish than other alloys.
5005 Aluminum sheet is often used when the material will be anodized and deployed in an architectural application like flashings, sills, curtain walls etc. Architects often specify 5005 alloy for anodized aluminum architectural metalwork.
Where anodizing is needed, 5005 is specified for applications similar to 1100 and 3003.
When anodised to improve corrosion resistance, the film on 5005 is clearer than on 3003, and gives better colour match with 6063 architectural extrusions.
5005 aluminum sheet VS 5052 aluminum alloy
Many people substitute 5052 for 5005. While 5052 can produce acceptable results, it has more imperfections and is more prone to color variation than 5005 alloy alumin
5005 properties and additional information:
5005 is a non-heat treatable alloy with magnesium content. It can be strengthened (hardened) by cold working. It scores well in weld-ability, formability, and corrosion resistance (especially when anodized).
5005 has excellent formability, especially in softer tempers. SAF carriers 5005 H34 temper which is slightly harder and is comparable to 5052 H32 for forming.
5005 alloy is noted for excellent welding characteristics. When 5005 material will be welded and then anodized, SAF recommends a 5356 welding wire for best color uniformity. Weld discoloration can still occur, but it is less severe than other welding alloys.
5005 machinability is generally fairly poor. Soft 5005 tempers machine worse than harder tempers. 5005 H34 and 5005 H38 can be machined, but with much more difficulty than many other aluminum alloys.
