The 5083 aluminum plates produced by haomei Aluminum are widely utilized for marine applications. While the standard state for these plates is H116, there are occasions where customers opt for H321. In the subsequent sections, the manufacturers of 5083 aluminum plates will elaborate on the distinctions between the H116 and H321 variants, thus assisting you in making informed choices.
1.H116: Aluminum alloy with a magnesium content of not less than 3.0%, the state after anti-corrosion treatment;
2.H321: The state of stabilizing the aluminum alloy with a magnesium content of not less than 3.0% after hardening.
H116: Magnesium content ≥4%, with good mechanical properties and anti-flaking corrosion performance.
H116 demonstrates excellent corrosion resistance, while H321 not only possesses comparable corrosion resistance but also exhibits superior stability. When compared to H116 aluminum plate, H321 boasts a higher hardness and improved stability. Furthermore, it maintains its excellent corrosion resistance even after being painted, making it suitable for use as a marine aluminum plate alongside H116.
Employing fiber laser technology to weld 5083 aluminum plates, by utilizing higher power settings of 5kw and 6kw under penetration welding conditions, and maintaining a welding speed within the range of 6m/min to 9m/min, results in achieving a superior quality weld.
