Industries :: Undersea & Marine

Overview

Over the last few centuries, many copper alloys were developed because of their corrosive resistance to saltwater and salt-laden atmospheres as well as their conductive properties.

Maritime Changes

In particular both Merchant Marine and Warships have seen significant changes due to copper alloys. For one, ship sizes are growing smaller than the large Queen Mary cruisers and traditional warships but nearly 1% of the construction is still comprised of copper and copper alloys.

War Countermeasures

Perhaps nowhere was copper as effective as in response to the German magnetic mines. To combat these mines, the allies applied the degaussing countermeasure of attaching a copper strip around the hull and passing a current through it to neutralize the ship's magnetic field.

Engine & Steam Room

Copper and copper alloys are primarily found in the engine and sea water pipelines of ships. To combat the harsh corrosive effects of sea water, marine condenser tubes of copper brass alloys are used extensively

Auxiliary Equipment

Copper and copper alloys are used in numerous items of auxiliary equipment including:

- cooling systems
- ships' evaporators
- low temperature steam lines
- pumps
- feed heaters
- valves
- miscellaneous coolers
- heating coils
