Creating metal parts is a major industry; from building cars to creating metal artwork, galvanized metal is used often and needs to be protected. There are a number of methods for plating galvanized metal so it won't rust or corrode as easily. The following are three common methods of coating these metals, but there are a number of other options as well.
Tin Zinc Plating
Tin zinc plating is used for a number of purposes from covering parts that require crimping at later stages to covering electrical parts that may need to be cut in the future. Tin zinc electroplating has its advantages; it is easy to solder, is highly conductive, and it is ductile, so it can be bent or adjusted when necessary. It's resistant to common things that would come into contact with electrical units, like salt water or sulfur dioxide.
Tin zinc plating is used as an alternative to cadmium plating. Cadmium is a toxic metal, so to eliminate this risk, tin zinc takes its place in most situations.
Zinc Iron Plating
Preventing corrosion takes the right kind of plating, and zinc iron alkaline plating is one option. It offers twice as much protection over zinc alone, and it's able to be applied thickly without abnormalities. Zinc iron is inexpensive, so it's one of the most economical options for reducing a part's rate of corrosion.
It's often used in brake components and fasteners that have to stand up to wear and tear over time. It also comes in multiple colors, including black and clear, which can be beneficial for visible parts or pieces.
Zinc Acid Chloride Plating
Zinc acid chloride plating is advantageous for those who want to save money. It's a cost-effective coating and is easy to use when coating cast iron. Hardened and heat-treated pieces can be covered with zinc acid chloride plating, making it good for a number of industries from automotive repair to industrial uses.
These are three common plating techniques, but there are several others that may be beneficial to you as well. Research the best and most cost-effective solutions for the material you're using; you may find that one of these is the best way to keep your construction vehicle, artwork, or other materials from corroding or rusting away over the next several months or years. A good coating can make a difference; if you notice damage starting, it's time to consider a second coating. Contact a company like Rogers Brothers Galvanizing for more info.
