Marine Materials

An Introduction

The Marine Industry poses a raft of requirements for engineering materials. The first one that comes to mind is the issue of corrosion many materials face in salt water solutions, so a resistance to these events is a must. With a specific weight of 1.025Kg/l, marine structures must also be incredibly strong to withstand the forces inflicted by seawater, both stationary and under pressure from, let alone the weight of ships and liners themselves.

 

Often within the world of engineering, there are crossovers within industries, and this is also true of the Marine industry. As well as all of the vessels used at sea level, including; boats, yachts, desalination plants etc, we also have to consider the uses of equipment which aren't utilising the sea itself, but are more interested in what lies beneath. Oil & Gas, for example, sits neatly within this particular segment, and the materials used must withstand both the marine environment and the chemical.

The materials and applications on this page are listed solely as a guide and do not reflect the limit of our supply, or the uses of said materials. If you have a specific application for which you need particular materials, please do not hesitate to contact us.

Aluminium

Pros

+ Straightforward to form into complex shapes, by drawing, extruding etc.

May be joined by welding, bonding and riveting, including to different materials

+ Excellent corrosion resistance to both fresh and seawater

+ High strength

+ Lightweight, aiding manoeverability, reducing fuel consumption and                       increasing performance

+ May be anodised to increase corrosion resistance, reduce scratching and             match colouring aesthetics
