In Jun 2023, Kinitics’ Shape Memory Alloy technology, utilized by Almatech, ensures reduced maintenance, enhanced accuracy, and reliability, all encapsulated within an electric spring-loaded actuator. Rigorous laboratory testing and real-world field trials validate its suitability for deployment in industrial environments. The KVA, an SMA bundled wire actuator, deployed at a natural gas production facility near Edson, Alberta. The company plans a commercial release of the KVA38 in the next two or three months.
In January 2023, Alps Alpine, a prominent manufacturer of voice-coil motor (VCM) systems for camera modules, announced the commencement of mass production of a shape-memory alloy (SMA) actuator designed for CMOS image sensor (CIS) camera modules. This technology leverages SMA wires to deliver precise and reliable optical image correction. Unlike conventional actuation systems reliant on bulky and intricate mechanisms, SMA actuation provides a compact and energy-efficient solution easily integrable into a variety of devices, including foldable smartphones where concerns about magnetic interference exist. Alps Alpine's mass production can potentially bring larger sensors, optics, and advanced image stabilization to a broader range of mid-range handsets.
Based on Alloy Type, this segment includes Nitinol (NiTi), Copper-Based Alloys, Iron-Based Alloys, Others. The Nitinol (NiTi) segment dominated the global market in 2024, while the Nitinol (NiTi) segment is projected to be the fastest–growing segment during the forecast period. In 2022, the nickel-titanium alloy category dominated the Shape Memory Alloy Market, holding the largest market share. It is anticipated to experience a Compound Annual Growth Rate (CAGR) of XX% from 2024 to 2035. The increasing demand for nickel-titanium (nitinol) shape-memory alloys, driven by the expanding medical and healthcare industry, especially in the field of medical implants, is a significant factor contributing to this growth.
Nickel-titanium alloy, in comparison to alternatives like copper-based alloy, iron-manganese-silicon alloy, and others, stands out due to its exceptional electrical and mechanical properties, extended fatigue life, high corrosion resistance, shape memory capabilities, biocompatibility, and super-elasticity. This alloy can revert to its original shape, transitioning from martensite to austenite, upon heating to its transition temperature. These distinctive characteristics of nickel-titanium alloy (nitinol) make it the preferred choice over other alloy types, propelling the growth of this segment.
Nitinol (NiTi) and its derivatives stand out as the commonly used shape-memory alloys, while copper and iron-based alloys are also accessible for specific purposes. Nitinol, however, comes with a higher cost, attributed to the need for exceptionally precise control over alloy composition during preparation. Even a slight 1% difference in the compositions of nickel (Ni) and titanium (Ti) can result in a significant shift of up to 150°C in transformation temperatures.
Based on the end use type, the Global Shape Memory Alloy Actuator market has been bifurcated into Medical, Aerospace & Defense, Automotive, Consumer Electronics, Others. The Automotive segment dominated the global market in 2024, while the Automotive segment is projected to be the fastest–growing segment during the forecast period. Shape memory alloy (SMA) actuators are the most common automotive application of SMA. SMA actuators are compact, lightweight, and offer silent operation, enhanced reliability, durability, and resistance to humidity, shock, and vibrations. The automotive sector presents diverse applications for shape memory alloys, especially in anticipation of forthcoming advancements.
Although these alloys are presently employed predominantly in the cooling circuit or for managing mixing valves, their pivotal role is anticipated to expand in the automation of vehicles. Actuators play a crucial role in the evolution of automated cars, and nickel-titanium-based shape memory alloys provide the prospect of noiseless phase transformation. Consequently, systems and actuators utilizing shape memory alloys can operate and respond silently, effectively eliminating any undesirable engine noise within the vehicle. In the automotive sector, European car manufacturers have long been using SMA actuators for transmission fluid control. Now, it is growing with the success in using a NiTiNb plug for sealing high-pressure fuel passages in diesel engine injectors.
SMA actuators continue to achieve steady growth in safety valves for both consumer and industrial applications. New actuator applications include a thermal interrupter for protecting lithium-ion battery from uncontrollable thermal runaway. In the automotive industry, SMA actuators can be used in various components such as radiator, fan clutch, engine, battery, brakes, headlight, sunroof, wipers, mirror, dashboard, airbags, pedestrian safety, and more. For instance, companies like Mercedes, BMW, General Motors (GM), Hyundai, Ford, Porsche, and Volkswagen (VW) have applied to SMA actuators to actuate lumbar support in car seats for passenger comfort.
Based on the Functionality Type, the Global Shape Memory Alloy Actuator market has been bifurcated into One-Way Actuation, Two-Way Actuation. The One-Way Actuation segment dominated the global market in 2024, while the Two-Way Actuation segment is projected to be the fastest–growing segment during the forecast period. One-way shape memory Valves And Actuators are a type of smart material that can be activated by heat to undergo a large, predetermined deformation. They are made from shape memory alloys (SMAs), which are a class of materials that can "remember" their original shape.
When an SMA is heated above its transition temperature, it transforms from a low-temperature martensitic phase to a high-temperature austenitic phase. This transformation is associated with a large change in shape, which can be harnessed to do work. One-way SMAs only exhibit the shape memory effect in one direction. This means that they can only remember one shape, and they will always return to that shape when heated above their transition temperature. This is in contrast to two-way SMAs, which can remember two shapes and can be trained to switch between them by applying heat and stress.
