learn about shape memory alloys

Shape Memory Alloys(SMA) are certain types of alloys that are well known as Tiniol for its Ti Ni Titanium and Nickel components, it can be doped with many other metals producing new characteristics of the alloy. The most noticeable behavior of SMA wires is its contraction with heating and expansion with cooling, unlike copper wires or any other metal wire that expands with heat and contracts with cool. To learn more about SMAs you can read the attached file.
