How to Calculate the Weight When Purchasing 5083 Aluminum Rods
To estimate the weight of a 5083 aluminum rod, use the formula:
Weight (kg) = π × (D² / 4) × L × ρ
- D = rod diameter (m)
- L = rod length (m)
- ρ = density of 5083 aluminum = 2,660 kg/m³

Frequently asked questions (FAQ)
What is a 5083 aluminum grade?
5083 aluminum alloy is a wrought aluminum–magnesium alloy containing 4.0–4.9% magnesium, known for its excellent corrosion resistance, good weldability, and high strength, making it ideal for marine and shipbuilding applications.
Is 5083 stronger than 6061?
5083-H116 has a tensile strength of approximately 317 MPa, comparable to 6061-T6 (around 310 MPa). However, 6061-T6’s yield strength (~276 MPa) exceeds that of 5083-H116 (~215 MPa). Overall, 6061 offers slightly higher strength, while 5083 excels in corrosion resistance and low-temperature toughness.
What is equivalent to 5083 aluminum?
Common equivalents for 5083 aluminum include EN AW-5083 (Europe), UNS A95083 (USA), ISO AlMg4.5Mn0.7, and JIS A5083 (Japan).
Is 5083 marine grade aluminum?
Yes, 5083-H116 is widely recognized as a marine-grade aluminum alloy due to its outstanding seawater corrosion resistance and excellent weldability, making it the preferred choice for ships, offshore platforms, and other marine structures.
