Aluminium 2018 is primarily intended for fabrication by forging and/or hot working. However it may be cold worked by conventional means but this should be done with the alloy in the annealed condition.

Principal Design Features | This is a high strength, age hardening, forging alloy. |

Aluminium 2018 Applications | Commonly used in the manufacture of aircraft engine cylinders and in heads and pistons. |
Aluminium 2018 Machinability | The alloy is readily machined, especially in the aged condition for smooth finishing. In the T4 condition (solution heat treated) the alloy is softer and may tend to build up during lathe turning or milling. Use of lubricating oils is recommended. |
Aluminium 2018 Forming | This is primarily a forging, or hot working, alloy. However cold working can be done with the alloy on the annealed condition. |
Aluminium 2018 Welding | Welding of this alloy by conventional methods is NOT recommended. It may be arc or resistance welded by special techniques |
Aluminium 2018 Heat Treatment | Solution heat treatment is done at 950 F for sufficient time to allow uniform heating throughout, then water quench. For heavy section size parts the water quench should be done using water at approximately 200 F. |
Aluminium 2018 Forging | Forging should be done in the temperature range of 900 to 970 F, finishing at 500 F before reheating to 970 F if necessary. |
Aluminium 2018 Hot Working | The alloy may be hot worked readily in the temperature range of 500 to 970 F. |
Aluminium 2018 Cold Working | This alloy is primarily intended for fabrication by forging and/or hot working. However it may be cold worked by conventional means but this should be done with the alloy in the annealed condition. |
Aluminium 2018 Annealing | Annealing ("O" temper) is done at 775 F for 3 hours and then controlled cooling at 50 F per hour down to 500 F, followed by air cooling. |
Aluminium 2018 Aging | Age hardening is accomplished starting with the alloy in the solution treated, T4, condition (950 F and water quenched). Age at 340 F for 10 hours followed by air cool for T61 temper . Age at 450 F for 6 hours and air cool for T71 temper. |
Aluminium 2018 Tempering | Not applicable. |
Aluminium 2018 Hardening | Hardens by heat treatment and aging and/or cold working. |
Aluminium 2018 Other Physical Props | Electrical conductivity 40% of copper. |
Aluminium 2018 Other Mechanical | Shear strength T61 temper 39 ksi. |
Density (lb / cu. in.) | 0.102 |
