Tensile Strength of Aluminium 3003 Alloy Sheet Metal

2023-04-06

The tensile strength of the aluminium 3003 alloy sheet metal is a parameter in the mechanical properties, which refers to the highest value of the suitable strength for the 3003 aluminum alloy sheet to break in the tensile testing machine. The tensile strength mainly reflects the fracture resistance of the 3003 aluminum sheet, which is an important indicator of the mechanical properties.

The tensile strength of aluminium 3003 alloy sheet metal is generally around 160-170mpa in H24 state, which is about 20% higher than that of 1060 aluminum sheet and 1100 aluminum sheet series. It belongs to an aluminum sheet product with relatively low tensile strength in the alloy aluminum sheet metal. It should be noted that the price of 3003 aluminum sheet is also relatively low, so for products with slightly superior requirements for tensile strength, 3003 aluminum alloy sheet metal can be selected.

Tensile strength (Rm) refers to the maximum stress value that the aluminium 3003 alloy sheet metal bears before breaking. When the aluminum sheet metal yields to a certain extent, due to the rearrangement of the internal grains, its resistance to deformation is improved again. Although the deformation develops rapidly at this time, it can only increase with the increase of stress until the stress reaches the maximum value. After that, the ability of the aluminum sheet to resist deformation was significantly reduced, and a large plastic deformation occurred at the weakest point, where the cross-section of the specimen shrank rapidly, and the necking phenomenon appeared, until it was broken. The maximum stress value of the aluminum sheet before tensile fracture is called the ultimate strength or tensile strength. Unit: N/cm2 (kilogram force per unit area). The domestic method of measuring tensile strength is to use universal material testing machine to determine the tensile/compressive strength of materials.
