1060 aluminium alloy is an aluminium-based alloy in the "commercially pure" wrought family (1000 or 1xxx series). It is fundamentally very similar to 1050 aluminium alloy, with the difference coming down to 0.1% aluminium by weight. However, while both 1050 and 1060 are covered by the same ISO standard, they are covered by different ASTM standards.
As a wrought alloy, it is typically formed by extrusion or rolling. It is commonly used in the electrical and chemical industries, on account of having high electrical conductivity, corrosion resistance, and workability. It has low mechanical strength compared to more significantly alloyed metals. It can be strengthened by cold working, but not by heat treatment.
Alternate designations include Al99.6 and A91060. It is described in the following standards:
ASTM B 209: Standard Specification for Aluminium and Aluminium-Alloy Sheet and Plate
ASTM B 210: Standard Specification for Aluminium and Aluminium-Alloy Drawn Seamless Tubes
ASTM B 211: Standard Specification for Aluminium and Aluminium-Alloy Bar, Rod, and Wire
ASTM B 221: Standard Specification for Aluminium and Aluminium-Alloy Extruded Bars, Rods, Wire, Profiles, and Tubes
ASTM B 483: Standard Specification for Aluminium and Aluminium-Alloy Drawn Tube and Pipe for General Purpose Applications
ISO 6361: Wrought Aluminium and Aluminium Alloy Sheets, Strips and Plates

Characteristics | |||
Principal Design Features | This is a relatively low strength, essentially pure aluminum, alloy. It is noted for excellent welding characteristics and formability along with good corrosion resistance. It cannot be hardened by heat treatment. | ||
Applications | Commonly used in the manufacture of chemical equipment and railroad tank cars. | ||
Machinability | The machinability of AL 1060 is fair to poor, especially in the soft temper conditions. In the harder (cold worked) tempers such as H16 and H18 the machining characteristics are improved. Either carbide or high-speed steel tooling may be used and use of lubricants is recommended, although some cutting may be done dry. | ||
Forming | This alloy has excellent forming capability by cold or hot working with commercial techniques. | ||
Welding | AL 1060 may be welded by standard commercial methods. If filler rod is required it should be of AL 1060. A precaution should be noted for the use of resistance welding as by this method some trial and error experimentation may be required to obtain good results. | ||
Heat Treatment | This alloy does not harden by heat treatment. It may be annealed after cold working. See "Annealing". | ||
Forging | This alloy may be forged in the temperature range of 950 to 700 F. | ||
Hot Working | Hot working, if required, may be done in the range of 900 to 500 F. | ||
Cold Working | The cold working characteristics of AL 1060 are excellent. It can readily be cold worked by all conventional methods. | ||
Annealing | Annealing may be done at 650 F followed by air cooling. | ||
Aging | Not applicable to this alloy. | ||
Tempering | Not applicable. | ||
Hardening | The alloy hardens only from cold working. Tempers H12, H14, H16, H18 are determined by the amount of cold working imparted into the alloy. | ||
Other Physical Props | Electrical conductivity 55% of copper. | ||
Other Mechanical Props | Shear strength of annealed (O temper) is 7 ksi. For H14 temper it is 9 ksi and for H18 temper 11 ksi. | ||

1060 aluminium alloy is very similar to 1050 aluminium alloy, the former has 99.60% aluminum and the latter has 99.70%, which means the difference is only 0.1% aluminum by weight. Both these two alloy products are covered by the same ISO standard but different ASTM standards. They have almost the same characteristics and applications.
Just like all 1xxx members, aluminum 1060’s machinability is poor, and does not harden by heat treatment (but it is possible to be annealed after cold working), also it is not typically used for high strength and high-pressure applications as it still belongs to pure aluminum.
It has excellent weldability and formability, actually the 1xxx series aluminum alloys have the most excellent weldability and formability which make them are suitable for many applications. 1060 aluminum alloy can be used by standard commercial methods for welding and it has strong corrosion resistance characteristics.
Based on its characteristics, 1060 aluminum alloy are widely used for products which have lower requirement for strength, such as reflector, billboard, decoration, kitchen wares, lamp holder, electric elements, chemical equipment, also because of the strong corrosion resistance characteristics, it can be used for the chemical storage, railroad tank cars and other equipment.
As a leading aluminum product provider, Aluminium Mart provides high quality 1060 aluminum alloy in different forms, including aluminum sheet, coil, plate, checkered plate, and etc. in order to meet all of your requirements.
