Nickel-Titanium Alloy Plate ASTM Standard

Nickel-Titanium Alloy Plate ASTM Standard

I.  Product Introduction:

Nickel-Titanium (Ni-Ti) alloy plates, which are manufactured and tested in compliance with ASTM, represent a premier class of shape memory and super-elastic metallic materials. These plates leverage the unique ability of Ni-Ti alloys to recover their original shape upon heating (Shape Memory Effect) or upon the removal of stress (Super-elasticity). Produced to precise dimensional and chemical specifications, they are engineered for high-performance applications demanding exceptional fatigue resistance, ductility, and bio-compatibility.

We Shaanxi Tilong Metal Material Co., Ltd. offer high-quality Nickel-Titanium alloy plates that meet international standards, ensuring precision and durability for your critical applications. Our products are manufactured using cutting-edge technology and undergo rigorous quality control processes to deliver optimal performance.

II. Identity & Composition:
1. Identity: This product is a wrought Nickel-Titanium (Ni-Ti) alloy plate, also commercially known as Nitinol, manufactured in full compliance with relevant ASTM International standards. The alloy's defining characteristic is its composition of Nickel and Titanium, which enables its unique functional properties of Super-elasticity and the Shape Memory Effect.

2. Core Value Proposition: Guaranteed ASTM Compliance:

Our Ni-Ti plates are produced under a stringent quality management system to meet or exceed the requirements of key ASTM standards. This ensures consistency, reliability, and traceability for critical applications. Compliance is verified through certified Material Test Reports (MTRS) with each shipment.

III. Key Technical Specifications:

Custom sizes and specifications are available upon request.

IV. Material Characteristics & Properties (per ASTM F2063):

1. Functional Properties:

Superelasticity: Exhibits a stress-induced martensitic transformation, allowing for extremely large, recoverable strains (typically 6-8%).

Shape Memory Effect: Can be deformed at a lower temperature and will recover its pre-programmed shape when heated above its Austenite finish (Af) temperature.

2. Mechanical Properties (Typical Ranges):

Ultimate Tensile Strength: 750 - 1100 MPa

Superelastic Plateau Stress: 400 - 700 MPa (dependent on Af temperature and strain)

Elongation at Break: 15% - 25% (for austenitic material)

3. Physical Properties:

Excellent Fatigue Resistance

Good Corrosion Resistance

Biocompatible (for grades intended for medical use)

High Damping Capacity

V. Processing Guidelines

1. Machining: Requires low-stress methods (EDM, laser cutting, abrasive waterjet). Conventional machining is challenging due to extreme work-hardening and toughness.

2. Forming: Can be formed in its martensitic state (softer) and then shape-set by constrained aging heat treatment.

3. Heat Treatment: Critical for setting shape memory/superelastic properties and transformation temperatures. Must be performed in a controlled, inert, or vacuum atmosphere to prevent oxidation and TiC formation.

4. Joining: Possible via laser welding, electron beam welding, or specialized brazing/soldering techniques with appropriate filler materials.

VI. Available Product Forms & Specifications:

1. Grades: Supplied in both Superelastic (SE) and Shape Memory (SM) grades, defined by their Austenite finish temperature (Af). Common tempers include SE508 (Af ~ -5°C to +15°C) and SM495 (Af ~ +45°C to +65°C).

2.Surface Condition: Hot-rolled, cold-rolled/annealed, pickled, centerless ground, or electropolished (for medical devices).

3. Condition: Solution Annealed, or as specified for further customer processing.

VII. Primary Application Industries:

1. Medical & Surgical: Vascular stents, orthopedic implants (bone plates, spinal rods), guidewires, orthodontic archwires, surgical staples, and minimally invasive surgical instruments.

2. Aerospace & Defense: Deployable structures, morphing wings, hydraulic line couplings, and silent release mechanisms.

3. Automotive: Advanced actuators, vibration dampeners, and thermal management valves.

4. Robotics & Automation: Biomimetic actuators, flexible grippers, and safety-release mechanisms.

5. Consumer Electronics: Antenna components, camera module actuators, and eyeglass frames.

6. Industrial: Pipe couplings for high-reliability applications, fluid control valves, and thermal actuators.

VIII. Product Features

1. Shape Memory Effect: Nickel-Titanium alloy plates exhibit a unique property known as the shape memory effect. They can revert to their original shape after deformation when heated, making them indispensable in various specialized applications.

2. Corrosion Resistance: These alloys offer excellent resistance to corrosion, making them ideal for harsh environments such as marine and chemical industries.

3. High Strength-to-Weight Ratio: With superior strength and lightweight properties, these alloys are used in aerospace and automotive sectors to reduce weight without compromising on strength.

4. Thermal Stability: Nickel-Titanium alloys are capable of withstanding high temperatures, making them suitable for use in engines, turbines, and other high-performance systems.

5. Biocompatibility: Often used in medical devices due to their biocompatibility, Nickel-Titanium alloys are ideal for implants and prosthetics.
