... There are many different bronze alloys but modern bronze is typically 88% copper and 12% tin. Alpha bronze consists of the alpha-solid solution of tin in copper. Alpha bronze alloys of 4–5% tin are used to make coins, springs, turbines and blades. Commercial bronze (90% copper and 10% zinc) and Arch ...

Shape-memory alloy
A shape-memory alloy (SMA, smart metal, memory metal, memory alloy, muscle wire, smart alloy) is an alloy that ""remembers"" its original shape and that when deformed returns to its pre-deformed shape when heated. This material is a lightweight, solid-state alternative to conventional actuators such as hydraulic, pneumatic, and motor-based systems. Shape-memory alloys have applications in industries including automotive, aerospace, biomedical and robotics.
