-
Nickel tubes, primarily composed of nickel and titanium, are special tubes with shape memory effect (recovering more than 95% deformation within a specified range) and superelasticity (recovering strain ≥8%).
They have high dimensional accuracy, with strictly controlled tolerances for outer diameter, wall thickness, etc. Straightness ≤0.5mm/m, roundness ≤0.03mm, exhibiting excellent performance. In terms of properties, tensile strength ≥900MPa, elongation ≥20%, good corrosion resistance, and excellent biocompatibility, meeting standards such as ISO 10993 and GB/T 16886.Category Specific Parameters Tolerance Range Performance Indicators (Typical Values) Specification Parameters Outer Diameter (mm) ±0.02-±0.10mm - Wall Thickness (mm) ±0.01-±0.05mm - Length (mm) ±0.5-±2.0mm - Inner Diameter (mm) ±0.03-±0.12mm - Tolerance Range Straightness (mm/m) ≤0.5mm/m. - Roundness (mm) ≤0.03mm - Performance Characteristics Transformation Temperature (°C) - Austenite transformation temperature (Af): 20-50°C; Martensite transformation temperature (Mf): -10-20°C Tensile Strength (MPa) - ≥900MPa Yield Strength (MPa) - ≥150MPa (Martensite); ≥500MPa (Austenite) Elongation (%) - ≥20% Fatigue Life (cycles) - ≥10⁶ cycles (under ±2% cyclic strain condition) Corrosion Resistance - Excellent, resistant to physiological fluid corrosion, conforms to ISO10993 standard Superelasticity (%) - Recoverable strain ≥8% Shape Memory Effect - Complete recovery rate ≥95% (within the specified deformation range) Biocompatibility - Non-cytotoxic, non-sensitizing, conforms to GB/T16886 standard Product Use/Application Scenarios
Nickel tubes are widely used in medical, aerospace, and mechanical manufacturing fields. For example, in the medical field, they can be used to manufacture interventional medical devices; in the aerospace field, they can be used for some special structural components.
Nickel tube offers excellent corrosion resistance, high temperature strength, and durability, widely used in chemical and energy industries.
