I. Chemical Composition:
Nickel Content: Generally, the nickel content is around 55% - 56.2%. The content of nickel elements significantly affects the phase transition temperature, shape memory characteristics, and mechanical properties of nickel-titanium alloys.
2. Titanium Content: The remainder is primarily composed of titanium, with the ratio of titanium to nickel determining the basic properties of the alloy.
3. Impurity Content: Typically, requirements include Carbon (C) ≤0.07, Hydrogen (H) ≤0.005, Oxygen (O) ≤0.050, Nitrogen (N) ≤0.05, etc. Lower impurity content ensures greater stability and purity in the alloy's performance.
II. Mechanical Properties:
Tensile Strength: Approximately 850 MPa
2. Yield Strength: 195MPa - 690MPa
3. Elongation: 25% - 50%
Nickel-titanium alloy capillary tubes feature the following characteristics:
