Overview
SMA26 is a nickel-titanium (NiTi) shape memory alloy renowned for its superior mechanical and thermal properties. Developed for high-stress applications, SMA26 exhibits remarkable shape memory effect and superelasticity, making it indispensable in industries requiring precision and durability. The alloy's ability to return to its original shape after deformation under specific temperature conditions has revolutionized fields such as aerospace and biomedical engineering. SMA26 is often preferred over conventional materials due to its fatigue resistance and long-term reliability.
Physical and Chemical Properties
SMA26 is characterized by a density of approximately 6.45 g/cm³ and a melting point around 1310°C. Its superelasticity allows it to withstand significant deformation without permanent damage, while its shape memory effect enables precise control in dynamic environments. Chemically, SMA26 is stable and resistant to corrosion, though prolonged exposure to harsh environments may degrade performance. The alloy's mechanical properties, including high tensile strength and fatigue resistance, make it suitable for cyclic loading applications.
Main Applications
SMA26 is widely used in aerospace for components such as actuators and vibration dampers, where its lightweight and high strength are critical. In the medical field, it is employed in stents and orthodontic wires due to its biocompatibility and flexibility. Robotics also benefits from SMA26, particularly in actuators and grippers that require precise, repeatable movements. The alloy's unique properties enable compact, energy-efficient designs that outperform traditional mechanical systems.
Safety and Storage
While SMA26 is non-toxic, proper handling is essential to prevent mechanical injuries. Sharp edges or sudden shape changes under thermal activation can pose risks. Storage should be in a dry, cool environment to avoid degradation. Avoid exposure to corrosive chemicals, which can compromise the alloy's performance. For long-term storage, protective packaging is recommended to maintain material integrity.
B2B Procurement Guide
When procuring SMA26, verify the alloy's composition and mechanical properties to ensure compliance with industry standards. Supplier certifications, such as ISO 13485 for medical applications, are critical for quality assurance. Consider lead times and minimum order quantities, as SMA26 is often custom-fabricated. Pricing varies based on purity and form (e.g., wire, sheet), so request detailed quotations. For reference, prices range approximately $200-$500 per kg.
