The construction materials that are used in land usually don't make the cut when used in the sea. Although some materials like wood and metal are adequate building materials, they might wear off in just a short time when used for structures that are used in the sea. That's why many shipbuilders consider Cunifer, a hard-wearing material that is perfect for use in structures often submerged in seawater.
Cunifer is a copper alloy made of three components, which are copper, nickel, and iron (Cu, Ni, and Fe). It's especially developed to be used in ships, yachts, and other structures and transportation devices that come in contact with seawater. A cunifer material specification that is crucial to ships is its high resistance to seawater decomposition. Unlike other metals, Cunifer goes through a chemical reaction when it's subjected to seawater. It develops a film coating to protect itself from corrosion. It also retains its deterioration resistance quality after welding.
It's also resistant to biofouling, or the buildup of sea biological creatures on its exterior, unlike other building supplies like timber. Biological fouling or biofouling is the process when biological materials build up on the surface of another matter. This commonly appears on submerged portions of structures, such as on the wooden posts of piers and on the hulls of ships. Biofouling creatures, such as mussels and barnacles, just slide off when subjected to flowing water instead of sticking on the surface of Cunifer.
The problem with Cunifer is that it's not inexpensive. Though it's an ideal shipbuilding supply, the start-up cost is not as low as the others. However, it is also low maintenance, which helps offset the start-up cost. There are other advantages of Cunifer also. It calls for fewer periodic cleaning just to get rid of the buildups, and it doesn't need to be covered with antifouling coatings since creatures adhere very poorly to it. Because it doesn't corrode, its plating can be thinner.
But much like many copper alloys, Cunifer is prone to staining due to the formation of oxides. It can be treated with a chromate-based cleansing agent, though, that can provide the material with a matte and gold-tinted form. But this treatment is considered expensive, that's why it's not always applied.
