cuzn38pb0.5. Forged lead brass copper tube is one of the commonly used materials for manufacturing precision mechanical parts, which has good mechanical properties, corrosion resistance and machinability. It is a kind of lead-toss-brass copper tube prepared by forging process, which has high strength and hardness, and can meet the manufacturing needs of various complex shapes of mechanical parts.
The preparation process of forged lead brass copper pipes is very complex and requires several steps. First of all, the selection and preparation of raw materials is very important, and it is necessary to select high-quality copper and zinc materials that meet the requirements and mix them in a certain proportion. The mixed raw material is then heated in a forging die to bring it to the right forging temperature. During the heating process, the cooling system of the forging die is constantly circulating to ensure that the die temperature remains stable.
When the raw material reaches the appropriate forging temperature, the forging operation begins. The forging process needs to be controlled by experienced operators to ensure the accuracy of the shape and size of the copper tube. During the forging process, the copper tube needs to be constantly cooled to prevent it from overheating or deforming.
