Zinc white copper C75400
Detailed information:
Brand: C75400 Standard: GB/T 4423-1992
Characteristics and Scope of Application:
For structural copper nickel alloys, their appearance has a beautiful silver white color, commonly known as German silver (originally Chinese silver). This alloy has high strength and corrosion resistance, good plasticity, and can withstand pressure processing well in both hot and cold states. It has poor machinability, poor weldability, and better elasticity than QSn6.5-0.1.
Chemical composition:
Copper Cu: 62.0-65.0
Nickel+Cobalt NiCo: 13.5-16.5
Zinc Zn: Excess
Lead Pb: ≤ zero point zero two
Phosphorus P: ≤ zero point zero zero five
Iron Fe: ≤ zero point five
Manganese Mn: ≤ zero point three
Silicon Si: ≤ zero point one five
Beryllium Sb: ≤ zero point zero zero two
Sulfur S: ≤ zero point zero one
Arsenic As: ≤ zero point zero one zero
Carbon C: ≤ zero point zero three
Bismuth Bi: ≤ zero point zero zero two
Magnesium Mg: ≤ zero point zero five
Note: ≤ 0.9 (impurities)
Mechanical properties:
Tensile strength σ b (MPa): ≥ 440
Elongation rate δ 10 (%): ≥ 5
Note: Longitudinal room temperature tensile mechanical properties of bar materials
Sample size: diameter or distance from opposite sides of 5-12
Heat treatment specification: casting temperature 1170 ℃; Annealing temperature 700-750 ℃; Rolling hot processing temperature 950-970 ℃; The low-temperature annealing temperature for eliminating internal stress is 250 ℃.
