Among the different types of pin badge, the most affordable options are:
Zinc alloy pin badges
Zinc alloy is an inexpensive metal that can be used to make pin badges. Zinc alloy pin badges have a silver finish and are lightweight and low-cost. However, zinc is not the most durable metal and the pin badges can bend or break more easily. The finish can also fade or tarnish over time. But for simple designs and temporary use, zinc alloy pin badges are a very budget-friendly choice.
Enamel pin badges
Enamel pin badges feature a metal base, typically brass or zinc alloy, with an enamel coating that is baked on. The enamel provides color and design details. Enamel pin badges are very affordable, fun and decorative. However, the enamel can chip or crack over time, especially with heavy use. For occasional wear, enamel pin badges are a great inexpensive option.
Stamped metal pin badges
Stamped metal pin badges are cut from thin sheets of metal, like brass or copper, and then stamped with a design. They have a vintage, rustic look and are quite affordable. However, the thin metal can dent or bend easily. Stamped metal badges suit simple designs best. With care, they can provide a long service life for the money.
Brass plated pin badges
Brass plated pin badges feature a base metal like zinc alloy or steel that is plated in brass. The brass plating gives them a bright gold finish at a lower cost than solid brass. Brass plating will eventually wear off with heavy use, but brass plated badges can still be an inexpensive choice for temporary badges or those used occasionally.
Pewter pin badges
Pewter is an affordable metal alloy that can be used to make simple pin badges. Pewter has a dull silver finish that dulls attractively over time. Pewter pin badges are inexpensive but provide a quality metal badge option. They work well for small productions and craft uses.
