1. Shape Memory Alloys (SMA) By Jessica Johnston, Fran D’Argenio, Becky Martin.

2. What Are Shape Memory Alloys? An alloy (a solution of two or more elements in a metallic matrix) that remembers its cold, forged shape and returns to it after having heat applied to it.

3. Examples of Shape Metal Alloys Are… Copper-Aluminium-Nickel Copper-Zinc-Aluminium Iron-Manganese-Silicon

4. Uses of Shape Metal Alloys Include… Dental Braces Tweezers Naval and Military Aircraft Safety Valves and Fire Sprinklers Spectacle Frames Deep fryers Underwire Bras Engine Mounts Fasteners, Seals, Connectors and Clamps Mobile Telephone Anntenaes

5. History of Shape Metal Alloys The first shape metal alloy was discovered in 1932. However, it wasn’t until the 1960s that the nickel-titanium SMAs were discovered by Buehler. His discovery formed the basis of the first commercial SMA.
