Iron: Iron is prized for its strength, durability, and affordability. While not as lustrous as precious metals such as gold, it is easy to pain, making it highly versatile.
Aluminum: This rustproof metal is soft, light, and malleable, making it easier to shape than heavier metals.
Zinc Alloy: Composed of varying quantities of copper and other metals, zinc alloys are ideal for the construction of lapel pins thanks to their fluidity during the construction process.
Bronze: Another alloy of copper, bronze is often used in a process called photo etching. Photo etching is ideal for creating intricate, complicated designs.
Copper: This material is popular in the use of the cloisonne (pronounced close-oh-neh) technique, which yields rich, artistic designs.
Precious Metals: Gold and silver are sometimes used to add highlights to lapel pins made of more conventional materials.
