Which of the properties of <strong>5083 H116 and H321
aluminium alloy sheets</strong> is better in marine application?<br>
It is necessary to know the difference between 5083H116 and 5083H321
aluminum alloy sheets.<br><br>
According to the contents of CCS Code for Materials and Welding:<br>
1. H116: Aluminum alloy with magnesium content not less than 3.0% after corrosion protection treatment.<br>
2. H321:Magnesium content not less than 3.0% of the
aluminium alloy after work hardening and stabilization treatment.<br>
Look at the relevant definitions of anti-corrosion treatment and hardening treatment (also refer to the national standard GB):<br>
H1* - Hot rolling, strong tension;<br>
H2* - Continuous casting and rolling, strong tension and partial toughening;<br>
H3* - After internal stress treatment, stable performance;<br>
H4* - Painted or coated;<br>
H*2-25% hardness treatment, H*4-50% hardness treatment;<br>
H*6-75% hardness treatment; H*8-90 hardness treatment.<br>
H116: Suitable for 5000 series
aluminium alloys with Mg content over 4%. These products have specified mechanical properties and anti-stripping corrosion properties.<br>
5083 H116 or 5083 H321 aluminium belong to <strong>marine
aluminium plate</strong>. They are widely used in marine lakes and oceans. Wide
aluminium plates and medium-thick
aluminium plates have high requirements for length and width. Usually, they are 2m long and 6m thick. In addition, they should be certified by classification societies. They are widely used in places where shipyards are concentrated.<br>
As a result, H116 has good corrosion resistance, H321 has better corrosion resistance and more stable performance. The mechanical properties of H116 and H321 are similar, and both of them have good corrosion resistance after coating. As far as I know, both of them can be used in ship construction, and more mechanical properties need to be provided by professional
aluminium plate manufacturers.</p>
