Shape Memory Alloy (SMA) Engineering & R&D
Advanced Shape Memory Alloy component design, thermal actuation modeling, and high-precision manufacturing. Delivering smart self-powered actuation across automotive, aerospace, and biomedical sectors.
Engineering Capabilities
TOSTA maintains deep expertise in Shape Memory Alloy (SMA) metallurgy, transformation temperature calibration ($A_s, A_f, M_s, M_f$), and nonlinear thermomechanical finite element modeling. Our proprietary SMA Thermostatic Valve Simulation System 2.0 achieves temperature control accuracy 2 to 3 times tighter than Chinese National Standard QB/T 2806-2017 and European Standard EN 1111-2019, providing reliable self-powered actuation with zero external electrical energy.
Available SMA Material Systems
Nickel-Titanium (NiTi / Nitinol)
Premier shape memory alloy offering reversible one-way and two-way memory effects, superelasticity, and high biocompatibility.
Copper-Zinc-Aluminum (CuZnAl)
Cost-effective copper-based alloy suitable for moderate temperature actuation and HVAC thermal relief dampers.
Copper-Aluminum-Nickel (CuAlNi)
High-temperature SMA maintaining thermal shape recovery up to 250°C in industrial heat exchangers.
Iron-Manganese-Silicon (FeMnSi)
Low raw-material cost system specifically suited for pipe coupling sleeves and static prestressing structural joints.
