Aluminum Alloy – 2024  

Aluminum Alloy 2024, a cold finished aluminum wrought product, is a high strength aluminum screw machine stock alloy. Typical tensile strengths in the -T351 and -T4 temper equal or exceed those of mild steels. The alloy has good machinability, surface finish capabilities and deep drilling characteristics.

 The high mechanical property levels of alloy 2024 make it ideal for applications requiring high strength.  Typical applications include aircraft fittings and structures, computer parts, gears, shafts, hinge pins, valve blocks and valve parts, bolts, nuts, fasteners, truck parts and brake components. The -T6 and -T851 tempers offer both an increase in strength and improved stress corrosion cracking resistance over the -T4 and -T351 tempers.

Machining of Aluminum Alloy 2024:

Alloy 2024 offers good machinability when machined using single-point or multi-spindle carbide tools on Screw machines. The use of a chip breaker is recommended. The alloy is rated “B” on the Aluminum Association machinability rating system, giving curled or easily broken chips with good to excellent surface finish.

Anodizing:

Anodizing response is rated moderate for the alloy. Alloy 2024 can accept all types of anodic coatings. The properties listed in this Alloy Data Sheet represent the best current information for this alloy. In each specific application, the user is expected to evaluate and test the alloy, temper and finishing method. Consult the Material Safety Data Sheet (MSDS) for proper safety and handling precautions when using alloy 2024.

Aluminum Alloy 2024 – Temper Designations and Definitions:

Standard Tempers

Standard Temper Definitions

T351

Solution heat-treated, cold worked, and naturally aged to a substantially stable condition. Applies to products that are cold worked to improve strength after solution heat-treatment, or in which the effect of cold work in flattening or straightening is recognized in mechanical property limits.

 

T4

Solution heat-treated and naturally aged to a substantially stable condition. Applies to products that are not cold worked after solution heat-treatment, or in which the effect of cold work in flattening or straightening may not be recognized in mechanical property limits.

T6

Solution heat-treated and then artificially aged. Applies to products that are not cold worked after solution heat-treatment, or in which the effect of cold work in flattening or straightening may not be recognized in mechanical property limits.

T851

Solution heat-treated, cold worked, and then artificially aged. Applies to products that are cold worked to improve strength, or in which the effect of cold work in flattening or straightening is recognized in mechanical property limits.
