Brass raw materials for the radiator valve refer to the quality and properties of brass used to manufacture a radiator valve. Brass alloys are composed of copper and zinc, which, when melted together, form an alloy with better properties than either metal has on its own. Properties enhanced by brass alloys include strength, corrosion resistance, malleability, and machinability. Different percentages of copper and zinc result in other brass alloys, each with unique properties that make it suited for specific applications. Radiator valves are just one example of where brass can improve performance.
