Aluminum 5083 General Description:
What is aluminum 5083?
5083 aluminium alloy is an aluminium–magnesium alloy with magnesium and traces of manganese and chromium. It is highly resistant to attack by seawater and industrial chemicals.
Alloy 5083 retains exceptional strength after welding. It has the highest strength of the non-heat treatable alloys with an Ultimate Tensile Strength of 317 MPa or 46000 psi and a Tensile Yield Strength of 228 MPa or 33000 psi. It is not recommended for use in temperatures in excess of 65 °C.Alloy 5083 is also commonly used in cryogenic applications due to it being able to be cooled to -195°C. At this temperature, the alloy has an increase in ultimate tensile strength of 40% and in yield strength of 10% as well as exhibiting excellent fracture toughness at such temperatures.
