Coated Metal: What is it?

Coated metal is created by adding a thin layer of dissimilar metals to a base metal, resulting in a stronger and more durable surface. Overlay, inlay, and contact cladding are different types of metal coating processes used to create coated metal objects with varying strengths and weaknesses.

Coated metal is metal that uses a thin layer or layers of dissimilar metals on top of less expensive or less durable base metals to create a stronger, more attractive, or otherwise more durable and desirable surface. In many cases, coated metals are a better option than galvanized or galvanized metals, as there is the ability to coat more types of metals than can be galvanized or galvanized. Additionally, the coating process used to create the coated metal is more durable and long lasting than a plating or zinc plating process. There are different types of metal cladding that is practiced, and each type has its strengths and weaknesses for different projects.

One type of metal coating process is known as overlay coating. To create this coated metal, one layer of metal is bonded to another by extreme heat and pressure. Overlay coating can bond dissimilar metals, such as nickel and gold or gold and silver, together, as well as join up to seven different layers of metal to achieve the strength and durability benefits of all seven in the finished product. Overlay cladding is also useful because it requires no adhesives, fillers, or solder, and is a permanent solution that will bond the metal together without worrying about it flaking later.

Inlay coating is another type of highly complex and extremely useful metal coating process used to create coated metal objects. With inlay trim, dissimilar metals can only be joined together where they are needed to be joined. For example, a piece of copper may be coated in a piece of gold exactly where it needs to be for when a weld is produced that transforms the finished product into a sculpture. The inlay coating also makes it possible to make the most of the characteristics of the different metals in the creation of the finished coated metal product.

Another use of cladding is contact cladding, where certain metals are coated together using heat and pressure to form perfectly conductive metals. An example of this might be a wire that needs to have the tensile strength of steel, but the electrical conductivity and corrosion resistance of copper. Using contact cladding, the two metals can be bonded together to obtain the benefits of both types of metal, without the possibility of a weld or fastener breaking or the material not being sufficient for the intended use required.
