Shape memory alloy Manufacturing Company: Applications of Shape Memory Alloys
Shape memory alloys have many successful applications in the aerospace field. Large antennas on satellites can be made of shape memory alloys. Before launching a satellite, the parabolic antenna is folded and placed inside the satellite. After the rocket launches and sends the satellite into its predetermined orbit, it only needs to be heated, and the folded satellite antenna will naturally unfold due to its "memory" function, restoring its parabolic shape.
Shape memory alloys are widely used in the clinical medical field, such as artificial bones, bone fixation devices, orthodontic treatment, intracavitary stents, embolization devices, cardiac prostheses, thrombus filters, interventional guidewires, and surgical sutures. Shape memory alloys play an irreplaceable role in modern medicine.
Shape memory alloys are also closely related to our daily lives. Take a shape memory alloy spring, for example. If you put the spring in hot water, its length will immediately increase; then, if you put it in cold water, it will immediately recover. Shape memory alloy springs can be used to control the water temperature of bathroom pipes. When the hot water temperature is too high, it can adjust or shut off the water supply pipe through its "memory" function to prevent scalding. It can also be made into fire alarm devices and safety devices for electrical equipment. When a fire occurs, the shape memory alloy spring deforms, activating the fire alarm device to achieve the purpose of alarming. A shape memory alloy spring can also be placed in a heating valve to maintain the temperature of a greenhouse, automatically opening or closing the heating valve when the temperature is too low or too high.
As a new type of functional material, many new uses for shape memory alloys are constantly being developed. For example, glasses frames made of shape memory alloys can be restored to their original shape by heating them in hot water if they are accidentally bent. In the near future, car bodies could also be made of shape memory alloys; if accidentally bumped, they can be restored to their original shape using a hairdryer, saving money and effort, which is very convenient.
Shape memory alloy Manufacturing Company: Special Properties of NiTinols
Superelasticity: Superelasticity refers to the phenomenon where a specimen, under external force, produces a strain far greater than its elastic limit strain, and the strain automatically recovers upon unloading.
Sensitivity to Oral Temperature Changes: The orthodontic force of stainless steel wire and CoCr alloy orthodontic wire is basically unaffected by oral temperature.
Corrosion Resistance: Studies have shown that the corrosion resistance of NiTi wire is similar to that of stainless steel wire.
Toxicity: The special chemical composition of NiTi shape memory alloy, that is, it is an atomic alloy of NiTi and other atoms, contains about 50% NiTinol, which is a known carcinogenic and cocarcinogenic substance.
Mild Orthodontic Force: Currently, commercially available dental orthodontic wires include austenitic stainless steel wire, cobalt-chromium-NiTinol alloy wire, NiTinol-chromium alloy wire, Australian alloy wire, gold alloy wire, and NiTinol wire. Good damping characteristics: The greater the vibration of the archwire caused by chewing and bruxism, the greater the damage to the tooth roots and periodontal tissues.
