What is Marine Grade 5086 Aluminum Plate?
Marine grade 5086 aluminum is an aluminum alloy specifically designed for marine applications requiring corrosion resistance and high strength. It belongs to the 5xxx series of aluminum alloys, which also includes 5052 and 5083.
5086 aluminum contains magnesium for excellent corrosion resistance and high strength. It also has good formability and weldability, making it easy to process and a popular choice for marine applications.
Some common marine applications for 5086 aluminum include hulls, decks and other structures exposed to salt water and other harsh environments. It is also used in other marine equipment such as gangways, frames and tanks.
Alloy 5086 aluminum plate is even stronger than 5052 or 5083, and its mechanical properties vary greatly with hardening and temperature. Not strengthened by heat treatment; instead, it becomes stronger due to strain hardening or cold working of the material. This alloy can be easily welded and retains most of its mechanical strength.
