Characteristics
CAMK67300 is a copper-zinc-manganese-silicon-lead copper-based multi-element (α+β) two-element alloy, which is a copper alloy with high strength and high wear resistance. The addition of silicon and manganese improves the strength and wear resistance of the alloy, and the addition of lead enhances its wear resistance and machinability. It has mechanical properties, casting properties, cutting properties and low cost, and has become one of the main manufacturing materials for propellers. one.
In polluted seawater, manganese brass will undergo de-Zn corrosion, and its resistance to cavitation corrosion is also poor, resulting in manganese brass propellers prone to corrosion fatigue fracture. The copper-zirconium binary phase diagram shows that when zirconium is added to manganese brass, the strengthening phase of Cu5Zr or Cu3Zr will be precipitated first, which will serve as the subsequent nucleation particles and play a role in fine-grain strengthening.
Application
In addition to being used to manufacture propellers, CAMK67300 can also be used to manufacture automobile synchronizer gear rings, bearing sleeves, gears, condensers, gate valves, etc.
