Tensile Strength Of Aluminum Sheet

Tempers t361 t861 were formerly designated t36 and t86 respectively.

Tensile strength of aluminum sheet. Tensile strengths of aluminum. Copper magnesium silicon manganese and zinc are used as alloying elements. 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. 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.

The secret to aluminum s strength comes down to chemistry. Below is a conversion chart that converts sheet metal gauge numbers into metal thickness. Common additives used to increase the strength and formability of aluminum include silicon magnesium and copper. In thicker sections it has elongation of 10.

More typical values are 310 mpa 45 ksi and 270 mpa 39 ksi respectively. It is the maximum stress that the sheet metal material is subjected to before pulling out. N mm2 or mpa the symbol is σb. The mechanical strength of aluminum can be increased by cold working and alloying.

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. A commercially pure aluminum with added manganese to increase its strength 20 stronger than the 1100 grade. The most widely used of all aluminum alloys. Pure aluminum is mixed with other elements to create high strength alloys.

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. Aluminum doesn t become brittle at low temperatures and retains its ductility. Aluminum has typical tensile strength between 40 mpa to 700 mpa. In thicknesses of 6 35 mm 0 250 in or less it has elongation of 8 or more.

Typical room temperature yield strength tensile strength and ductility values for some of the aluminum alloys are given in the following chart. It has an ultimate tensile strength of at least 290 mpa 42 ksi and yield strength of at least 240 mpa 35 ksi. The secret to strength. 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.

It is one of the indexes of metal strength. It is the maximum stress that the cross section is subjected to when the load is applied between the two points of the. The temper designations mainly have 6061 t4 t451 al 6061 t6 6061 t651 etc. And properties of material in the basic temper.
