The purpose of this invention is to make shape memory alloy containing copper or cobalt. Once SMA has been shaped at a specific temperature, reheating it to the set temperature automatically restores its original shape if it has been deformed at a temperature below the original set temperature. Even if it has been severely bent at a temperature exceeding the set temperature, removing the bending stress will return the alloy to its original shape. The set temperature to be required original shape recovery is able to set as user purposes. To search this invention, Dialog was used as a search tool.
Invention disclosure is about shape memory alloys.
Nickel or Titanium is based in the composition of alloy. Impurities like cobalt or copper are added to make the alloy's properties better. The compositions of the alloy seriously affect the physical properties of the alloy. Assume you focus in the composition of alloys instead of products like tooth splint, eye glass frame, etc. when you make a novelty search this invention. Then you look through Manual of Classification noting compositions of the alloy in the class 420 focusing nickel or titanium base containing cobalt or copper.
