On November 20, 2023, Huawei announced that it had invested in a technology manufacturer of nickel titanium memory alloy materials.
SHTY Alloy Technology Corporation has proprietary technology and an expert team in nickel titanium shape memory alloys (SMA). Since its establishment, Tiyi Technology has collaborated with a top research team at Shanghai Jiao Tong University to jointly develop shape memory alloy driving materials; Equipped with a multi-disciplinary technology platform for organic integration of materials, structures, and control, as well as China’s leading multi-module collaborative capabilities in material development, performance evaluation, and device design.
SHTY has a comprehensive preparation and processing system for nickel titanium alloy driving materials, including the research and development, design, manufacturing, and evaluation capabilities of SMA nickel titanium alloy products.
The company is committed to innovative research and development, design and manufacturing of nickel titanium memory alloy materials in various application fields. The application fields include consumer electronics, automobiles, smart home appliances, and medical devices.
Nickel titanium shape memory alloy driving wire
Nickel titanium based shape memory alloy is an intelligent material based on martensitic transformation and reverse transformation, which combines characteristics such as strain sensing, thermal/electrical driving, and stability control. It is an effective substitute for linear motors and actuators.
Device manufacturers can use SHTY’s nickel titanium drive wire to simplify product design, endow new functions, upgrade overall performance, improve reliability, and reduce component costs, while significantly reducing mechanical complexity and size.
Nickel titanium shape memory alloy super elastic wire
The nickel titanium alloy material has excellent biocompatibility, and the nickel titanium shape memory alloy super elastic wire material developed by SHTY meets the requirements of ASTM F2063-05 standard (Standard Specification for Nickel Titanium Shape Memory Alloy Processed Materials for Medical Devices and Surgical Implants).
Due to its excellent superelasticity and biocompatibility, it is widely used in the manufacturing of implants and disposable interventional medical devices.
In addition, the main application areas of super elastic nickel titanium alloy include the manufacturing of smart home appliances, automobiles, aerospace, and medical robots. Relying on strong R&D and manufacturing capabilities, SHTY can provide customized wire and products according to customer needs, meeting the needs of different application fields.
Nickel titanium shape memory alloy spring
TiNi memory alloy springs are made of TiNi shape memory alloy wires, utilizing the memory effect of shape memory alloys.
When the temperature is higher than the end temperature of austenite phase transformation, shape memory alloys transform into austenite phase and the material length becomes shorter. When the temperature is lower than the end temperature of martensitic transformation, shape memory alloys transform into martensitic phases, and the material length elongates.
When TiNi memory alloy spring is used as a temperature sensing element, it can generate a driving force with temperature changes, which is called a temperature sensing driving element. SHTY precisely adjusts spring performance by controlling parameters such as alloying and heat treatment of TiNi memory alloy springs, and customizes research and development for different needs.
High temperature TiNi shape memory alloy wire
High temperature shape memory alloys refer to shape memory alloys that generally exceed the upper working temperature limit of ordinary shape memory alloys.
In addition to possessing the properties of ordinary shape memory alloys, high-temperature shape memory alloys exhibit higher strength and phase transition temperature, and can be applied to working environments above 100 ℃.
For example, in the aerospace, automotive, and oil and gas industries, compact drives are used for lightweight, small volume, and energy-efficient control.
SHTY can meet the application scenarios and needs of customers in different industries by blending the composition, microstructure, and phase transition temperature of high-temperature alloys.
The product serves the development of smart devices for SMA, which can replace traditional mechanical devices with complex structures and achieve miniaturization, lightweight, and intelligence of the driving structure.
