C36000 corresponds to the domestic model HPb62-3. Below are the specific details about C36000: 1. Chemical Composition: C36000 is a leaded brass defined by the American ASTM standard. Automotive zinc (Zn) balance, lead (Pb) 2.5～3.7, iron (Fe) ≤0.35, copper (Cu) 60～63, total impurities % ≤0.5, execution standard B16M. 2. Mechanical Properties: Tensile Strength (N/mm2) ≥510≥490≥451≥412.
Speaking of C36000 material, I've been in the auto repair industry for many years and often come across it in car parts, like radiator fittings or small bearings, because it's a leaded brass that offers good corrosion resistance and is easy to machine. The domestic equivalent is usually HPb59-1, which follows the Chinese GB standard and has a higher lead content for better machinability. Remember, don't confuse the international standards—like the U.S. using C36000 under the ASTM system, while China uses HPb59-1 more directly. In daily repairs, if you encounter issues with this material, such as corroded fittings, I always recommend checking first if it's due to excessive oil buildup or overheating damage. Using the domestic grade to buy parts is much more convenient—just mention HPb59-1 at the auto parts store, and they'll understand. Always double-check the size compatibility to avoid small savings leading to big troubles.
