Aluminum products made of aluminum and other alloying elements. Usually it is first processed into casting products, forging products and foils, plates, belts, pipes, rods, profiles, etc., and then made by cold bending, sawing, drilling, assembly, coloring and other processes. The main metal element is aluminum, and some alloying elements are added to improve the performance of aluminum.
Originally referring to the alloy of copper and tin, bronze later encompasses copper alloys other than brass and nickel silver, often prefixed with the name of the primary additive element.
Brass is an alloy composed of copper and zinc. Brass made from just copper and zinc is known as ordinary brass. If the alloy includes two or more elements, it is referred to as special brass. Brass is noted for its strong wear resistance and is commonly used to manufacture valves, water pipes, connectors for air conditioning units, and radiators, among other items.
