High-elastic alloy is a precision alloy with a certain degree of special physical, chemical and mechanical properties of the alloy series. Mainly used for a variety of precision instruments or mechanical devices on the elastic. This article reviews recent progress in the development of highly elastic alloys abroad. The main contents of the introduction are: 1. High corrosion-resistant flexible metal materials; 2. High temperature and high elasticity of metal materials; 3. Low temperature and high elasticity of metal materials; 4. Low relaxation alloy 5. High proportion of the limit, high elastic limit of the metal material; Special mechanical and physical properties of highly elastic alloy; 7. The current research in foreign countries. This article focuses on the performance of the alloy and the process were introduced, and the application of some new alloys are described. The article also briefly introduces the foreign research trends and development trends.
