1.0mm 1.2mm 1.5mm nitinol wire shape memory nickel titanium wire

Nitinol wire is a memory metal that has the ability to restore its original shape under certain circumstances. Guide wires are the most widely used use of nickel titanium wire. 1.0mm 1.2mm 1.5mm nitinol wire shape memory nickel titanium wire has low hardness, high flexibility, and is not easily deformed. It is the best choice for guide wires that need to gently shuttle through blood vessels and digestive tract without damaging tissue. Its titanium content is close to 50% and has good biocompatibility.

Characteristics of nickel-titanium alloy

When creating and manufacturing this wire, there are several qualities that will affect the final application: Dimensions, tolerances, and mechanical properties (including tensile strength, elongation, and surface quality) are examples of physical properties.

Size and tolerance are two aspects of nature. Dimensions: Nitinol is extremely abrasive to drawing dies and must be passed through these dies multiple times to achieve the tiny diameters required in the medical industry. Tolerances: Tight tolerances must be maintained on diameter, but it is equally important that the tolerance remains constant along the entire length of the wire. This facilitates overall use of the drawing die and minimizes wear.

Tensile strength, elongation, and condition are mechanical properties. Nitinol ultrafine wire is usually processed under two conditions: cold working and direct annealing. This preference depends on the production procedures used by the medical device OEM. In the next manufacturing layer, most of the wire will be heat-set to a superelastic state.

Producing a high-quality product while cutting costs during production requires careful management of every factor throughout the 1.0mm 1.2mm 1.5mm nitinol wire shape memory nickel titanium wire and ensuring that all of its dimensions are consistent. Precision machinery is required to maintain these properties because even small changes in the coil reinforcement manufacturing process can create problems, such as useless parts or excess scrap.

Properties of nickel titanium alloy wire

The most notable features of this alloy are its well-known shape memory and superelasticity. The metal's shape memory properties allow it to "remember" and maintain its previous shape when heated above its transformation temperature. This happens because nickel and titanium have different crystal structures. This pseudo-elastic metal is also approximately 10 to 30 times more elastic than any other metal.

The following are some basic mechanical and physical properties of this alloy:

Physical characteristics include:

Wires containing Nitinol metal have a dazzling silver appearance.

The density of this type of alloy is 6.45 gm/cm3.

The melting point of Nitinol wire is approximately 1310 °C.

Their resistivity ranges from 76 ohm-cm at low temperatures to 82 ohm-cm at high temperatures.

In terms of thermal conductivity, the metal has a thermal conductivity of 0.1 W/cm-°C.

Heat Capacity: Its heat capacity is 0.077 cal/gm-°C.

Latent Heat: The latent heat of this substance is 5.78 cal/g.

Its magnetic susceptibility is 2.5 at low temperatures and 3.8 emu-gm at high temperatures.

Technical/mechanical characteristics include:

The ultimate tensile strength of Nitinol wire ranges from 754 to 960 MPa.

Elongation at break is typically around 15.5%.

The average yield strength at high temperatures is said to be 560 MPa; at low temperatures, it is known to be 100 MPa.

The elastic modulus is approximately 75 GPa at high temperatures and 28 GPa at low temperatures.

Poisson's ratio is approximately 0.3.
