FAQ in Marine-grade Aluminum

What difference between marine grade aluminium vs aluminium?

Marine-grade aluminum has better corrosion resistance, especially in marine climates, due to alloys like Al-Mg. Common aluminum lacks this specialization, having varied alloy compositions and lesser corrosion resistance.

What are the Common Alloys Used in Marine Grade Aluminum Sheets?

Common alloys include 5052 and 6061. While 5052 is known for optimal durability, 6061 is a cost-effective choice with slightly lower durability but still adequate for many marine applications.

What Makes 5083 Marine-Grade Aluminum Ideal for Hostile Environments?

The 5083 marine-grade aluminum has superlative corrosion resistance in hostile environments. It's the strongest non-heat treatable aluminum alloy and retains its strength even post-welding, which is beneficial in shipbuilding and other marine structures.

What’s the difference between 6061 and 5052 aluminum?

The surface of 5052 aluminum alloy is smoother and less likely to break due to bending after forming. The 6061 aluminum alloy is easier to machine and has better heat dissipation. 5052 is a non-heat-treatable aluminum alloy, while 6061 is a heat-treatable aluminum alloy.

What’s the difference between 6061 and 6063 marine aluminum?

6063 aluminum alloy has better corrosion resistance and is more suitable for extrusion processing. The 6061 aluminum alloy has higher strength and is more suitable for machining.
