Constellium aluminium solutions are used by shipbuilders to produce light and fast vessels capable of resisting the corrosive effects of seawater. This is achieved by a combination of highly specialized alloys, dedicated surface treatments, cutting-edge production processes, and well-honed manufacturing skills.
Dedicated technical partnership for large aluminium extrusions
In close cooperation with customers - shipbuilders in Europe, America and Australia - Constellium has developed innovative solutions for the manufacturing of welded structures in large extruded profiles. We are now the #1 supplier of large profiles in Europe. Large extrusions reduce the amount of welding work required by up to 50%, and lower the extent of welding-related problems such as distortion resulting rectification work. In addition, the heat-affected zones are significantly reduced.
We work closely with shipbuilding customers, and our engineers are on hand to provide advice and assistance. Our expertise and these close technical partnerships deliver significant benefits for our customers:
We also provide dedicated surface treatments, highly specialized alloys such as SEALIUM®, cutting-edge production processes, and well-honed manufacturing skills.
High-tech aluminium plates for yachts, tankers, ferries and many more vessels
In addition to extrusions, we also offer a variety of plates. Our plates are used in yachts, tankers for liquefied natural gas, ferries, oil rig work boats and many more vessels. They are available in a standard width of 2,000 mm and standard lengths of 5,000 and 6,000 mm. We also provide checkered plates for marine ramps. These are light yet hardwearing and strong.
SEALIUM®, a specially designed alloy
We have created SEALIUM®, an alloy that is considerably stronger than other alloys commonly used in shipbuilding. It provides major weight savings for designers and operators of fast ferries, Coast Guard launches and yachts, where high performance is required. Easy to weld, flexible and simple to shape and bend, it provides assembly advantages. It also delivers high protection against corrosion and impact resistance.
Large extruded profiles can reduce the required welding work by 50%. Constellium is Europe’s #1 supplier of large profiles.
