Fastener Material
To begin with, you'll want to make sure that you are choosing the right materials. One of the best things about high-quality fasteners is that they can be made from any number of different metal materials. Among the most common types of metals and alloys to be used for fasteners include brass, bronze, copper, stainless steel, alloy steels, and titanium.

Custom Rivets

These are also formed using the cold heading process. Rivets can be made from Steel, Aluminum and even Brass. Care must be taken in the grade of the metal chosen for the application. Too hard of a grade and the rivet will not be able to be flattened in the tool to properly attach the two parts. Too soft and the rivet may stress fracture or even pull through the hole when from the movement of the two parts.

The strength of the fasteners depends not only on the material that is used to manufacture but also on what finishing has been applied. The finish provides a protective layer on the fasteners that helps prevent corrosion. Popular finishes include black oxide, aluminum hot-dip galvanizing, zinc or chrome plating, as well as another custom plating.
