ASTM B171 C71500 Copper-Nickel 70/30 Plate
"Brass plate" typically refers to a brass nameplate or a brass plaque, often used for identification purposes, such as being affixed to doors, walls, or coffins to indicate a name, title, or other information. Brass, a metal alloy primarily composed of copper and zinc, is chosen for its durability, resistance to corrosion, and aesthetic appeal. The term "brass plate" can also refer to a thicker sheet of brass material, though its primary usage is in the context of nameplates or plaques.
