memory alloy

Memory alloy, often known as shape memory alloy, is a marvel of materials science that snaps back to its original shape when heated. The most famous example is nickel-titanium (Nitinol), prized for its superelasticity and shape memory properties. These alloys find their way into medical devices, actuators, and even eyeglass frames, because who doesn't want glasses that can survive a tumble? Operating temperatures and transformation ranges vary, but they're typically within a comfortable range for practical applications.

Prices vary wildly depending on purity and form, with small quantities costing upwards of a few hundred AUD per kilogram. Used components can sometimes be found on tradingpost.com.au if you're feeling adventurous. Consult official materials science documentation for precise specs and handling guidelines—don't go bending your Nitinol pipe dream without knowing what you're doing.
