What are Ni-Ti Alloys?

The purchasing pace at the demand end of the international thermal coal market continues to slow down and the international thermal coal price continues to decline. Prices for thermal coal at major international ports continued to fall last week as buyers in Europe slowed in recent days for April, coupled with weaker-than-expected import demand from End users in China. According to China Coal Market net monitoring:  Australia Newcastle port thermal coal price index was 253 USD/ton, compared with 309.02 USD/ton, down 56.02 USD/ton, down 18.13%. South Africa's Port Richards thermal coal price Index was $264.5 / mt, down the US $62.72 / mt or 19.17% from US $327.22 / mt. The European ARA Tri-port thermal coal price Index was $281.8 / ton. Does the price of thermal coal in major international ports continue to decline to affect the price of the nitinol powder? 

What are Ni-Ti Alloys?

Ni-Ti alloy, also known as Nitinol, is a metallic alloy of nickel and titanium in which the two elements are present in roughly equal atomic percentages. Different alloys are named according to the percentage of nickel by weight; For example, Nitinol 55 and Nitinol 60. It exhibits shape memory effect and superelasticity at different temperatures.

Nitinol alloys exhibit two closely related and unique properties: shape memory effect and superelasticity (also known as pseudo-elasticity). Shape memory is the ability of Nitinol to withstand deformation at a certain temperature, retain its deformed shape when external forces are removed, and then restore its original undeformed shape when heated above its "transition temperature". Superelasticity is the ability of a metal to withstand large deformations and return to its undeformed shape immediately after the removal of external loads. Nitinol has 10-30 times the deformability of a normal metal and returns to its original shape. Whether Nitinol has shape memory or superelasticity depends on whether it is above the transition temperature of a particular alloy. Below the transition temperature, it exhibits shape memory effects, above which it exhibits superelasticity. 

What are Shape Memory Alloys?

"Memory metal" is also called "shape memory alloy", is a special alloy material, mainly in nickel titanium alloy. 

It can be plastic deformation like plastic at a certain temperature. But at a certain temperature, it can be restored to its original state, with a certain "memory". 

The deformation recovery ability of shape memory alloy is attributed to the thermoelastic martensitic transformation in the material during deformation. 

Shape memory alloys are known for their excellent memory, flexibility and plasticity. In addition, it has good wear resistance, fatigue resistance and corrosion resistance.

What are Shape Memory Alloys Used For?

Shape memory alloys are widely used in aerospace, mechatronics, biomedicine, bridge construction, automobile industry, and daily life. 

Automobile industry 

The use of memory metal alloy as a radial material, can enhance the bearing capacity of the tire, super elastic characteristics also reduce the possibility of tire burst, improve driving safety. 

The air bags in the seat, under certain pressure, the waist rest on the seat can be perfectly fitted to the driver or passenger's waist. 

In addition, memory alloys are used in the manufacture of actuators to make car trunks easier to close, and in the manufacture of valves to control noise and vibration in engines and improve noise, vibration and vibration roughness. 

Aeronautics and astronautics 

It is used to develop lightweight, quiet, and efficient designs. The variable-section fan nozzles, shock absorbers and actuators are all made of metal alloys. These devices are austenitic at normal temperatures and convert to martensite (and the desired shape) as they cool due to temperature changes caused by airflow around the aircraft or changes in ambient temperature during normal flight. 

Building 

Memory alloys help to prestress Bridges or buildings. On a smaller scale, shape memory materials can be used to enhance the reliability of pipe fittings in piping systems. 

Medical 

The application of memory alloys in biomedicine could reduce the need for medical intervention. For example, medical stents can be inserted into arteries to improve blood flow in a minimally invasive way in patients with heart disease. Micro-actuators and artificial muscles rely on memory alloys to create robotic prosthetic organs that help amputees move more freely.
