National Standard 59 Brass Rod, Straight Grain Brass Rod, Brass Tube, with High Strength and Excellent Plasticity

HPb59-1 lead brass is a widely used lead brass. It features good machinability, excellent mechanical properties, can withstand cold and hot pressure processing, easy to weld, good brazing, good stability against general corrosion, but has a tendency to stress corrosion cracking. It is mainly used in air conditioning valves, hardware machinery, etc.
