Marine Aluminum Extrusions: The Ultimate FAQ Guide

Why is Aluminum Suitable for Marine Applications?

Aluminum is the best metal for marine applications due to the following reasons:

  • It is precipitation hardened and has high resistance to corrosion thus increasing the durability of the marine applications.
  • It has very high tensile strength that allows you to use it even in the harsh marine environmental conditions.
  • It is light in weight thus reducing the overall weight of the marine equipment.
  • Aluminum is also easy to handle with a lot of ease in welding and assembling.

What Alloys are Suitable for Marine Aluminum Extrusions?

The suitable aluminum alloys for marine extrusion are 5083, 5086. 6082 and 6061 of aluminum alloys.

The aluminum alloy series consists of the following:

  • Aluminum-magnesium alloys 5000 series which you can use for marine roll materials.

The most common ones are 5083 and 5383

  • Aluminum-magnesium-silicon alloys 6000 series which you can use for marine extruded sections.

The most common ones are 6082, 6061, 6005A, and 6060 series.

What are Marine Aluminum Extrusions?

Marine aluminum extrusions are aluminum objects with definitive cross-sectional area that you can use in different marine applications.

Which Surface Finishing is applied on Marine Aluminum Extrusions?

There are different types of surface finishing that you can apply on marine aluminum extrusions.

The most common one is anodized surface finishing which increases film thickness to 20 micrometers.

It protects the marine aluminum extrusions from external damages such as corrosion.

Apart from that, it extends the life of the products while giving it the perfect appearance.

You can choose to add other colors on the anodized aluminum to increase its visual appeal.

How does Wellste Guarantee Quality of Marine Aluminum Extrusion?

What are the Important Parameters of Marine Aluminum Extrusion?

Some of the key parameters include:

  • Anti-corrosion/corrosion resistance
  • Anti-ultraviolet
  • Hardness
  • Extraordinary performance with good surface finish
  • Weldability & fabricability
  • Certain tensile, yield strength & elongation etc properties

How do you Manufacture Marine Aluminum Extrusion?

You can manufacture marine aluminum extrusions by going through the following processes:

  • Preparation Stage

This is the stage where you will prepare the extrusion machines and materials in readiness for the extrusion process.

  • Heating the Aluminum

After confirming that all the machine and materials are okay, you will start the extrusion process by heating the aluminum.

  • Shaping the aluminum

After that you will pour the hot, molten aluminum into the extrusion material.

The extrusion material will assume the shape of the material that you desire to have.

With the assistance of a machine, you will force the hot metal through the extrusion design.

  • Cooling Process

After that you will cool it down to the right temperature thus forming the marine aluminum extrusion of choice.

What’s more, you will anodize the extrusion to protect it from external damages and make it corrosion resistant.

Where are Marine Aluminum Extrusions used?



You can use the marine extrusion in different applications among them being on cruise ships, kayaks, mega yachts, and military vessels.

You can use marine aluminum extrusions to make:

  • Aluminum boat trims
  • Aluminum boat handrails
  • Boat trailers and ladders
  • Boat gratings and deck houses
  • Boat windscreen frames

Does Wellste make Custom Dies for Marine Aluminum Extrusions?
