Tensile Strength of Aluminium 3003 Alloy Sheet Metal

The tensile strength of aluminum alloy sheet metal 3003 is a crucial parameter in its mechanical properties. It represents the maximum force that the 3003 aluminum alloy sheet can withstand before breaking in a tensile testing machine. This value primarily reflects the fracture resistance of the 3003 aluminum sheet and serves as a critical indicator of its mechanical properties.

Aluminum alloy sheet metal of the 3003 series typically exhibits a tensile strength of approximately 160-170 MPa in the H24 state, which is roughly 20% higher than that of the 1060 and 1100 aluminum sheet series. It falls into the category of aluminum sheet products with relatively lower tensile strength within the alloy sheet metal range. It's worth noting that the price of 3003 aluminum sheet is comparatively lower. Therefore, for products requiring slightly superior tensile strength, 3003 aluminum alloy sheet metal can be a suitable choice.

Tensile strength (Rm) is the maximum stress that an aluminum 3003 alloy sheet can withstand before breaking. As the aluminum sheet undergoes deformation, its resistance to further deformation increases due to the rearrangement of internal grains. However, once the stress reaches its maximum value, the aluminum sheet's ability to resist deformation decreases significantly. At this point, the weakest point of the sheet experiences large plastic deformation, resulting in rapid shrinking of the cross-section and the appearance of necking until failure occurs. The ultimate stress value of the aluminum sheet before tensile fracture is known as its ultimate strength or tensile strength, measured in N/cm2 (kilogram force per unit area). The tensile strength is typically determined using a universal material testing machine.
