If you’re in the market for a pontoon boat, you’ve probably noticed that most pontoon boats are made from aluminum. Aluminum is an extremely popular material for pontoon boats because it’s lightweight, strong, durable, and resistant to corrosion. But? In this article, we’ll take a closer look at the different types of aluminum used in pontoon boats.
Marine-Grade Aluminum
Most pontoon boats are made from marine-grade aluminum, which is a type of aluminum that’s specifically designed for use in saltwater environments. Marine-grade aluminum is alloyed with magnesium and chromium to make it stronger and more corrosion-resistant. It’s also treated with a protective coating to prevent rust and corrosion. Marine-grade aluminum is ideal for pontoon boats because it can withstand the harsh conditions of saltwater without deteriorating.
6000 Series Aluminum
The most common type of aluminum used in pontoon boats is the 6000 series, which includes alloys 6061 and 6063. 6061 is the most commonly used alloy and is known for its high strength-to-weight ratio, good corrosion resistance, and excellent workability. It’s often used for structural components such as the frame and decking. 6063 is similar to 6061 but is better suited for extrusions because it’s more heat-treatable.
5000 Series Aluminum
Another type of aluminum that’s sometimes used in pontoon boats is the 5000 series, which includes alloys 5052 and 5083. 5052 is a medium-strength alloy with good corrosion resistance and is often used for the pontoons themselves. 5083 is a high-strength alloy with excellent corrosion resistance and is sometimes used for the frame and decking.
In summary, pontoon boats are typically made from marine-grade aluminum that’s alloyed with magnesium and chromium to make it stronger and more corrosion-resistant. The most commonly used aluminum alloys for pontoon boats are the 6000 series, which includes alloys 6061 and 6063, and the 5000 series, which includes alloys 5052 and 5083. If you’re in the market for a pontoon boat, it’s important to consider the type of aluminum used in its construction to ensure that it’s strong and durable enough to meet your needs.
