Tensile Strength Of Aluminum Sheet

In thicknesses of 6 35 mm 0 250 in or less it has elongation of 8 or more.

Tensile strength of aluminum sheet.

6061 aluminum alloy al 6061 t6 6061 t651 6061 t4 al 6061 aluminum alloy is a general purpose structural alloy developed by alcoa in 1935. Below is a conversion chart that converts sheet metal gauge numbers into metal thickness. When this is an issue 2024 is commonly used in an anodized finish or in clad form thin surface layer of high purity aluminum known as alclad. N mm2 or mpa the symbol is σb.

1 aluminum 5083 h 116 plate as an example has a yield strength of around 34 000 psi and an ultimate strength of around 45 000 psi. It is the maximum stress that the cross section is subjected to when the load is applied between the two points of the. Pure aluminum is mixed with other elements to create high strength alloys. It is one of the indexes of metal strength.

In thicker sections it has elongation of 10. In brittle materials the ultimate tensile strength is close to the yield point whereas in ductile materials the ultimate tensile strength can be higher. And properties of material in the basic temper. The temper designations mainly have 6061 t4 t451 al 6061 t6 6061 t651 etc.

Ultimate tensile strength uts often shortened to tensile strength ts ultimate strength or within equations is the maximum stress that a material can withstand while being stretched or pulled before breaking. Aluminum has typical tensile strength between 40 mpa to 700 mpa. We can see that the plastic range of aluminum is considerably less than steel around 11 000 psi plastic range for aluminum or roughly 24 of the material s ultimate. Common additives used to increase the strength and formability of aluminum include silicon magnesium and copper.

The mechanical strength of aluminum can be increased by cold working and alloying. Copper magnesium silicon manganese and zinc are used as alloying elements. Tempers t361 t861 were formerly designated t36 and t86 respectively. Tensile strengths of aluminum.

The secret to aluminum s strength comes down to chemistry. The most widely used of all aluminum alloys. A commercially pure aluminum with added manganese to increase its strength 20 stronger than the 1100 grade. Aluminum doesn t become brittle at low temperatures and retains its ductility.

More typical values are 310 mpa 45 ksi and 270 mpa 39 ksi respectively. The tensile strength of pure aluminium is around 90 mpa but this can be increased to over 690 mpa for some heat treatable alloys. Mechanical properties of selected aluminium alloys. The secret to strength.
