Bronze wear plates are made from a variety of bronze alloys. A wear plate is a piece of very hard material that’s used to reduce the friction between two surfaces that rub against each other, and thus to extend the lifetime of mechanical parts. The exact alloy used for a bronze wear plate can vary, but most bronze wear plates are made from some variation of high-strength bronze alloys. These alloys often contain elements such as aluminum, nickel, manganese, or silicon to increase their strength and wear resistance.
