Nickel titanium ingots are usually made through vacuum arc remelting or induction melting. Vacuum arc remelting helps in purifying the alloy and ensuring a homogeneous structure. Induction melting is also used for its efficiency in melting the metals and controlling the composition precisely. After melting, casting processes are employed to shape the molten alloy into ingots.

Shape memory Ni Ti ingot is a kind of Ni-Ti alloy ingot. They have a unique ability to "remember" their original shape. When they are deformed under certain conditions, they can be restored to a predetermined shape after heating to a specific phase transition temperature. This property is due to reversible phase transitions in the alloy's crystal structure, making it very useful in many applications such as medical devices and aerospace components.

The temperature has a significant effect on the performance of Ni-Ti ingot. Nickel-titanium phase transition occurs at different temperatures. Below the transition temperature, it is more malleable. On this basis, shape memory effects and superelasticity become prominent.

Stretched nickel titanium ingot can be used for shape memory applications.
Nitinol alloy has shape memory effect, which is based on its unique crystal structure and phase transition characteristics. For example, in the medical field, the stretched nickel titanium ingot can be used to manufacture a vascular stent, the stent is stretched and compressed at low temperature, which is convenient to put into the vascular intervention device, and after entering the human blood vessel, under the action of body temperature (higher than the phase change temperature), the stent will restore the original design shape, open the blood vessel, and restore the normal circulation of blood.

Typical applications for stretched nickel titanium ingot include making medical stents because it has shape memory and superelasticity to support blood vessels. They are also used in orthodontic wire to provide gentle and constant force for orthodontics. In the aerospace sector, it can be used to make components such as connectors that need to maintain performance under different conditions.

There are several ways to control the phase change temperature of Ni Ti ingot.
First, adjusting the composition, especially the ratio of nickel to titanium, can change the phase transition temperature.
Secondly, the temperature is regulated by processing technology such as heat treatment.
Third, doping with other elements such as copper or niobium also helps control the phase transition temperature.

Nickel titanium ingots generally have good elasticity and shape memory ability. They also possess relatively high strength and corrosion resistance.

The ASTM2063 nickel titanium ingot has shape memory and superelasticity and is mainly used in the manufacture of medical implants. They are also used in aerospace components that require high-performance alloys to withstand a variety of conditions.

Manufacturing ASTM2063 nickel titanium ingot has the following challenges:
The first is the composition control, to accurately control the proportion of nickel and titanium, small composition deviation may lead to performance does not meet the standard.
The second is the melting process, nickel-titanium alloy is prone to segregation during melting. That is, the distribution of alloying elements is uneven, which will affect the overall quality and performance consistency of the spindle.
In addition, hot processing, in the process of hot processing, the temperature range should be strictly controlled. Due to the characteristics of Nitinol such as phase transition temperature, it is very sensitive to hot working temperature, and inappropriate temperature will change the microstructure of the alloy, which will affect its shape memory effect and other key properties.

ASTM ensures the quality of nickel titanium plates by setting strict material composition requirements. It also defines precise mechanical performance criteria such as strength and elasticity. In addition, ASTM provides detailed test methods, such as chemical analysis and mechanical properties testing, to verify quality.

ASTM ensures the quality of ASTM F2063 Shape Memory Alloy Nitinol Plate through setting strict material composition requirements. It also defines precise mechanical property standards such as strength and elasticity. Additionally, ASTM provides detailed testing methods like chemical analysis and mechanical performance testing to verify the quality.

Medical devices like stents and orthopedic implants rely on nickel titanium plates that comply with ASTM F2063. Aerospace components such as engine parts and stabilizers also depend on them. In the automotive sector, these sheets are used for engine and suspension components. Electronic products, including some springs and connectors in electronic devices, also rely on this nickel-titanium plate.
