Both 5052 and 5083 are members of <strong>marine grade aluminum</strong> magnesium alloy, but the two differs in magnesium content that eventually leads to differences in chemical properties, mechanical properties and application.<br><br></p>
<p>
Chemical composition of <strong>5052
aluminum sheet</strong>:</p>
<p>
Si 0+ Fe0.45 Cu 0.1 Mn 0.1 Mg 2.2-2.8 Cr 0.15-0.35 Zn 0.1</p>
<p>
Chemical composition of 5083
aluminum plate:</p>
<p>
Si 0.4 Fe0.4 Cu0.1 Mn0.3-1.0 Mg4.0-4.9 Cr 0.05-0.25 Zn 0.25</p>
<p>
The difference in chemical composition makes the difference in mechanical properties between the two. No matter the tensile strength or yield strength, <strong>5083
aluminum plate</strong> is much stronger than 5052
aluminum plate.<br></p>
<p>
The following figure shows the difference of the same thickness between 5052 and 5083:<br>

Different chemical compositions lead to different mechanical properties, and different mechanical properties eventually lead to different uses between them. 5052
aluminum sheet has good forming ability, corrosion resistance, candlelight, fatigue strength and medium static strength. It is often used in the manufacture of aircraft fuel tank, oil pipe, as well as the sheet metal parts of traffic vehicles and ships, instruments, street lamp brackets and rivets, hardware products, etc. Aluminum sheet 5083 is often used in situations requiring high corrosion resistance, good welding ability and medium strength, such as welding parts of ship, automobile and aircraft plates; pressure vessels, cooling devices, TV towers, drilling equipment, transportation equipment, missile components, assembly, etc. requiring strict fire protection.</p>
