Process and material of metal buttons


The current metal buttons are mainly made of four materials: copper, alloy, stainless steel and iron. Copper, stainless steel, and iron are all stamped out by a punch, then electroplated or sprayed in various colors, and then assembled into a button. The alloy button is produced by a die-casting machine. The alloy button is relatively heavy, but it can be made into any shape required by the customer. The alloy button is polished and then electroplated in various colors, or sprayed, electrophoresed, etc., and then assembled into A button that the customer needs.
