Fastener Material Selection & Plating Guide
Selecting the proper fastener material and finish can make or break a project—especially those with intended applications underwater or in harsh environments. With many options available, many professionals struggle to find the best choice for their application. Below, we’ll cover choosing an appropriate fastener material for your project and provide guidelines regarding finish selection.
Choosing the Best Fastener Material for Your Project
Fasteners can be manufactured from a wide variety of materials, and the available coating and finishing options help users tailor a solution specific to their application. Alloy steels, aluminum, and carbon steel all see frequent use, but manufacturers can also create fasteners from numerous plastics, brass, nylon, and other materials.
Fastener Finishes Options
The ideal finish depends heavily on the intended end use of the fastener. Many finishes can help to prevent corrosion or increase strength. The materials used to create and finish fasteners can heavily impact their ideal use; the strength, brittleness, corrosion resistance, and cost of these materials all vary and play into the selection process before fabrication begins.
What Is Galvanic Corrosion? How Can It Be Avoided?
Galvanic corrosion takes place when incompatible metals come into electrical contact while submerged in water or salt water. The first metal (the anode) corrodes more quickly while the other (the cathode) corrodes at a slower rate, resulting in half of the component material corroding away.
Careful material selection mitigates the risk of galvanic corrosion. Dissimilar material combinations should be avoided when selecting metal paneling, trim, and fasteners for underwater applications.
