In 1980, Professor Zhang Zhifang, the founder of the company, began the development of nickel titanium based shape memory alloys.
In 1998, Beijing GEE SMA Technology Co., Ltd(GEE SMA) was established, becoming one of the first companies in China to specialize in producing Nitinol products.
In 2000, the company gradually improved its Nitinol material production line, with 100% of the production processes completed internally and 70% of the inspections completed by itself.
In 2005, the company began to establish cooperative relationships with well-known domestic universities and enterprises, and the jointly developed Nitinol materials and components have been applied in many important fields.
In 2019. Zhuozhou GEE SMA Technology Co., Ltd was established as a Production and Research & Development base.
At the end of 2023, the company established a foreign website and began directly providing Nitinol products to foreign countries.

Beijing GEE SMA Technology Co., Ltd. (GEE SMA) has accumulated a strong workforce of approximately 65 and a comprehensive manufacturing capacity on closed loop processing, including melting, forging, rolling, drawing, grinding, polishing, electro sparking and laser processing, etc. GEE SMA has equipped with several sets of melting furnace, drawing and straighten machine, custom-made muffle furnace, sheet rolling machine, wire rolling machine and so on. GEE SMA mainly produce NITINOL SHAPE MEMORY ALLOY sheet, bar, wire, tube and components, especially high-quality plate with thickness from 0.01mm to 10 mm and wire with diameter from from 0.01mm to 7mm up by annual production capacity of 200 tons. GEE SMA owns many of the most advanced technologies such as NITINOL SHAPE MEMORY ALLOYS deep-processing, molding and heat treatment, based on a wide variety of NITINOL SHAPE MEMORY ALLOYS material with both one-way and two-way memory effects for super elasticity, temperature controlling and memory actuating device applications, among them, the training technique of the two-way memory heat engine is a leading in the world. GEE SMA is now a leading global supplier of NITINOL SHAPE MEMORY ALLOY products for customers in USA, Germany, UK, Japan and Korea on medical facilities and communication technology, as well as the designated production enterprise of many national biomedical industry, aerospace and scientific research institutes.
Beijing GEE SMA Technology Co., Ltd. (GEE SMA) adheres to the concept of environmental protection production to melt ingot by more than 99.95% high purity titanium sponge and electrolytic nickel under the 10-2 pa level 3 vacuum equipment. its subsequent processes have been strict filtering system to realize the production without dust emissions. Our NITINOL SHAPE MEMORY ALLOYS product can be stable to the standards ASTM F2063.The super-elastic wires (glasses wire, antenna wire, fishing wire, etc.) are widely used in the high-end market, at the same time the shape memory wire and micro wire (from dia.0.01 to dia. 0.15mm ) are widely used in toy manufacturing, electronic drive, automatic control and other industries. The processing range of Ultra-thin strip and nanocomposite materials can be reached form dia. 0.01mm to dia.0.3mm. In addition, according to the market demand, our company has developed a variety of memory alloy profiles and multicomponent shape memory alloy materials, which provides great convenience for related enterprises at home and abroad. To create a high-quality global market for civilian goods is our future development direction.
