Metal buttons are usually made from strong and durable metal materials that can withstand pressure and frequent use in garments. The main materials used include brass, zinc alloy, stainless steel, aluminum, and sometimes copper. These metals are chosen because they are sturdy, long-lasting, and easy to shape into different button designs. During manufacturing, the metal sheets or wires are stamped or molded into button shapes and then polished or electroplated with coatings such as nickel, gold, or antique finishes to improve their appearance and prevent rust. These materials help ensure that metal buttons remain strong, durable, and stylish for use in jeans, jackets, coats, bags, and other garments.
