The tensile strength of brass rods is usually between 300 and 500MPa (depending on the zinc content), which is much higher than that of pure copper at 200 to 300 mpa, while maintaining good plasticity (elongation 15% to 40%). This characteristic of "combining strength and plasticity" enables it to withstand dynamic loads (such as vibration and impact), and also to achieve complex shape forming through cold working (stamping, bending) or hot working (extrusion, casting). For instance, H62 brass containing 30% zinc (62% copper and 38% zinc) is widely used in automotive parts. It has a tensile strength of 370MPa and an elongation of 25%, perfectly balancing strength and processability.
