1: Brief Introduction Of 2014 aluminum alloy  

2014 aluminium alloy is an aluminium-based alloy often used in the aerospace industry.
It is easily machined in certain tempers, and among the strongest available aluminium alloys, as well as having high
hardness. However, it is difficult to weld, as it is subject to cracking.
2014 is the second most popular of the 2000-series aluminum alloys, after 2024 aluminum alloy. It is commonly extruded
and forged. The corrosion resistance of this alloy is particularly poor. To combat this, it is often clad with pure aluminum.
If unclad 2014 aluminum is to be exposed to the elements, it should be painted as a corrosion protection measure.
Prior to the adoption of The Aluminum Association alloy designations in 1954, 2014 was known by the industry conventional
designation "14S".
Principal Design Features:        
This is a precipitation hardening alloy with good strength after heat treatment.
Applications:        
Commonly used in the manufacture of aircraft structures, and truck frames.
Machinability:
Machinability is good in the annealed condition, somewhat more difficult in the heat treated conditions. For lathe cutting use
15 degree top rake, 20 degree side rake and 10 degree clearance. Use of a lubricant, such as oil or kerosene, is
recommended for all machining.
Forming:    
The alloy may be formed by conventional means. However tight bend radius should be avoided and forming is best done
in the T4 or T3 temper.
Welding:    
Welding should be done by inert gas consumable electrode arc method for best results. The alloy is subject to cracking
during welding so fixturing should be arranged for minimum strain. Use either 2014 or 2017 alloy filler rod.
Heat Treatment:
Heat at 935 F for sufficient time for thorough heating of part then water quench. This produces T4 temper. Various
tempers are derived after this heat treatment by subsequent cold work.
Hot Working:
Hot working is accomplished in the range of 300 to 400 F.
Hardening:
Hardening is accomplished by a precipitation heat treatment at 935 F followed by water quench. This produces T4 temper.
Other tempers (mechanical properties) result from additional cold work after this treatment and then by a 320 F heat
treatment for T6510 and T6511 tempers.
Annealing:
Anneal at 775 F for 2 to 3 hours followed by controlled cooling at 50 F per hour down to 500 F. Then air cool.
Other Mechanical Props:        
Shear strength: O (annealed) temper 18 ksi, T4 temper 38 ksi, T6 temper 42 ksi
