Overview of Nitinol Powder:

Nitinol, also known as Nickel-titanium alloy, is a metal alloy of nickel and titanium, in which the atomic percentages of the two elements are approximately equal. Different alloys are named according to the weight percentage of nickel(such as nickel). Nitinol 55 and Nitinol 60.It shows shape memory effect and super elasticity at different temperatures.Miron Nitinol powder, Ni-Ti alloy powder Particle size: 15-53 microns Ni:Ti:5:5 or as your request Purity: 99.9%.Sphere Percentage: 99.9% (Min) Production Method: Laser Evaporation.

What memory alloy is Nitinol?Nitinol is a shape memory alloy,a special alloy that can automatically restore its plastic deformation to its original shape at a certain temperature.Its expansion rate exceeds 20%,fatigue life is 7 times that of 1*10,its damping characteristics are 10 times that of ordinary springs,and its corrosion resistance is better than the best medical stainless steel at present,so it can meet a variety of requirements in engineering It is an excellent functional material that can meet the needs of medical applications.

In addition to having a unique shape memory function,memory alloys also have excellent properties such as wear resistance,corrosion resistance, high damping and super elasticity.

Characteristics of nitinol?Nitinol has two closely related and unique properties:shape memory effect and superelasticity(also known as pseudoelasticity).Shape memory is the ability of Nitinol to deform at a certain temperature,maintain its deformed shape when external force is removed,and then restore its original undeformed shape when heated to above its"transition temperature".Superelasticity is the ability of a metal to withstand large deformations and immediately restore its undeformed shape after the external load is removed.The deformation of Nitinol is 10 to 30 times that of ordinary metals and can restore its original shape.Whether Nitinol alloy shows shape memory effect or superelasticity depends on whether it is higher than the transition temperature of the specific alloy.Below the transition temperature,it exhibits a shape memory effect.

Two main melting methods of nitinol?Nitinol is extremely difficult to produce due to the need for very strict composition control and excellent titanium reactivity.Every atom in titanium that binds to oxygen or carbon is taken from the NiTi lattice,which changes the composition and lowers the phase transition temperature.There are two main melting methods:Vacuum arc remelting(VAR)

This is achieved by generating an arc between the raw material and the water-cooled copper contact plate.The melting is done under high vacuum,and the mold itself is water-cooled copper.

Vacuum induction melting(VIM)

This is done by heating the raw material in a crucible(usually carbon)using an alternating magnetic field.This is also done under high vacuum.

Although these two methods have their advantages,it has been proven that compared with the VART smelting process,the VIM smelting process material has fewer inclusions and therefore has higher fatigue resistance.Other research reports pointed out that the use of ultra-high purity plasticizers in raw materials can reduce the number of inclusions and improve fatigue performance.Other methods can also be used on a boutique scale,including plasma arc melting, induction skull melting,and electron beam melting.Physical vapor deposition is also used on a laboratory scale.

Hot processing of Nitinol is relatively easy,but cold processing is difficult,because the huge elasticity of the alloy increases the contact between the mold or the roller,which leads to huge frictional resistance and tool wear.For similar reasons,processing is very difficult,and to make matters worse,the thermal conductivity of Nitinol is very poor,so it is difficult to dissipate heat.Grinding(abrasive cutting),electrical discharge machining(EDM)and laser cutting are all relatively easy.

Application of Nitinol Powder:

What is the scope of application of Nitinol powder?

Nitinol powder can meet the needs of various engineering and medical applications,and it is an excellent functional material.In addition to the unique shape memory function,the memory alloy also has wear resistance,corrosion resistance,high damping and super elasticity.Excellent functionality.

The tensile strength of Nitinol can reach 1000 MPa.In other words,it takes more than 100 dry grams per square millimeter to destroy it.This force is stronger than ordinary steel,and it also has good"memory"performance and corrosion resistance.

Nitinol alloy contains 50%nickel and 50% titanium,that is to say,nickel and titanium are equally divided,each accounting for half.The temperature range of the shape memory can be adjusted by the control component.Generally,the higher the nickel content of Nitinol,the lower the operating temperature.When it contains 55% nickel and 45% titanium,the memory alloy can work at room temperature.

People have used this characteristic of shape memory alloys to make pearl necklaces and bracelets made of shape memory alloy wires,and bras woven from shape memory alloy wires.Wearing these decorations and health products on the body will restore the original curvature and rigidity under the action of body temperature,thus playing a role of decoration and health care.In addition,you can also use Nitinol to make orthodontic wires to correct deformed teeth based on the body's oral temperature.

Nitinol can be used to replace traditional actuators(solenoid valves,servo motors,etc.),such as the simple hexapod robot Stiquito.

Nitinol springs are used in fluid thermal valves,where the material acts as both a temperature sensor and an actuator.

The alloy is used as an auto-focus actuator in sports cameras and as an optical image stabilizer in mobile phones.

Alloys are used in pneumatic valves to obtain a comfortable seat,which has become an industry standard.

The alloy Chevrolet Corvette contains a nickel-titanium memory alloy actuator that replaces the heavier electronic transmission to open and close the hatch to release air from the torso,making it more accessible .
