2014A Guide: Properties, Applications and Design Considerations

__________

 
What is 2014A?

 

2014A aluminium is a readily available high strength grade of commercial aluminium. The aerospace equivalents are L93 (plate), L157 (sheet) and L168 (bar). L168 is the most widely used aluminium bar alloy in the aerospace industry.

Supplied in a fully heat-treated condition, 2014A is a 4-5% copper alloy.

Similar or obsolete designation and trade names

The most common temper is:

  • T651 (except under 10mm and over 203.2mm diameter which is supplied in T6 only) which is solution heat treated, stress relieved by stretching then artificially aged.

Other tempers include:

  • T3 - Solution heat treated, cold worked and naturally aged
  • T6511 - Solution heat treated and stress-relieved by stretching then artificially aged with minor straightening after aging - Equivalent to T4 condition.
Other designations: Al Cu4 Si Mg / AlCu4SiMg (ISO) | BS L102 - Bars / Sections | QQ-A-200/2 | BS L168 - Bars / Sections | UNS A92014 | HE15 | H15 (Former BS) | A92014 | BS H15 | W Nr. 3.1254 / 3.1255 | AMS 4121 | BS1474 Bar | BS1470 Sheet/Plate | Duralumin | Al-P12 (AECMA) | AlCuSiMn (Germany DIN) | 3.1255 (Germany Werkstoff) | A-U4SG (France AFNOR) | P-AlCu4.4MnMg3501 (Italy Old UNI) | 9002/3 (Italy New UNI) | 14-4338 (Sweden) | AlCu4SiMn (Switzerland)

 

Industry Examples: Aerospace | Military & Defence | Civil Engineering

 

Typical Components & Applications: High strength structural components | High technology market applications | Aerospace fittings | Military vehicles | Aircraft structures | Truck frames | Bridges | Weapons

 


Main Attributes:
  • Exceptionally high strength
  • Very good machinability
  • Heat treatable and retains good strength after heat treatment
  • After heat treatment, behaves very much like low-carbon steel
  • Poor resistance to atmospheric attack, especially in marine environments (therefore often hard anodised)
  • Unsuitable for welding/brazing/soldering
  • Great for parts needing good strength up to 150°C

Note For Designers:

2014A has high strength but poor corrosion resistance. Parts are often anodised in order to protect the surface of the metal. Should the extra strength not be critical, aluminium 6082 which has excellent corrosion resistance may be a better option.

2014A can be protected against atmospheric corrosion whilst in storage by being lightly coated with a Lanolin-based protective oil.

Please do give us a call if you want to chat through the options.


Finishing & Treatments:

2014A is suitable for a range of finishings and treatments.

It is often hard anodised due to its poor corrosion resistance. If colour anodising is required, only dark colours should be considered.

2014A can also be plated and powder coated.

See our Finishing Processes page for further information on services that we can facilitate.
