Nitinol flower/SMA metal flower/Nitinol custom shape memory alloy

Nickel Titanium (also known as Nitinol or NiTi) is in the unique class of shape memory alloys. A thermoelastic martensitic phase transformation in the material is responsible for its extraordinary properties. Nitinol alloys are typically made of 55%-56% Nickel and 44%-45% Titanium.
Small changes in composition can significantly impact the properties of the material. There are two primary categories of Nitinol. The first, known as "SuperElastic", is characterized by extraordinary recoverable strains and kink resistance.
The second category, "Shape Memory" alloys, is valued for the Nitinol's capacity to recover a pre-set shape when heated above its transformation temprature. The first category is often used for fishing. SZNK makes shape memory alloys, which are primarily useful for actuators, used in many different mechanical devices.

Here's a general step-by-step guide to creating a nitinol flower:

Cut the nitinol wire to the desired length for the stem and petals of the flower. The length will depend on the size of the flower you want to create.

Use pliers to shape the nitinol wire into a stem. You can create curves or bends to make it more visually appealing.

Cut smaller lengths of nitinol wire for the petals. The number of petals will depend on the desired flower design.

Shape each nitinol wire petal by bending it into a curved or petal-like shape. You can experiment with different shapes and sizes for a unique look.

Attach the petals to the stem by wrapping the ends of the petal wires around the stem or twisting them together. Ensure they are securely attached.

Optionally, wrap floral tape or colored tape around the stem and petal wires to give the flower a more finished and decorative appearance. You can also add additional embellishments like beads, ribbons, or fabric flowers to enhance the design.

It's important to note that working with nitinol wire can be challenging as it has shape memory properties and can return to its original shape when heated. Therefore, take care when bending or shaping the wire to achieve the desired flower shape.
