There are various standards for nickel titanium alloy wire, and the following are some common standards:

national standard:

GB/T 20569-2006 "Nickel titanium shape memory alloy wires for surgical implants": specifies the requirements for nickel titanium shape memory alloy wires for surgical implants, including chemical composition, mechanical properties, dimensions and deviations, surface quality, and other aspects. For example, there are clear regulations on the nickel titanium atomic ratio, tensile strength, elongation, etc. of alloys to ensure their safety and reliability in medical applications.

GB/T 33824-2017 "Nickel titanium shape memory alloy wire": applicable to general use nickel titanium shape memory alloy wire, it specifies its technical requirements, test methods, inspection rules, as well as marking, packaging, transportation, storage and other contents. This standard specifies performance indicators such as shape memory characteristics and phase transition temperature range for alloy wires.

International standards:

ISO 6474-1: The 2017 "Nickel Titanium Shape Memory Alloy for Surgical Implants Part 1: Wire" is a standard published by the International Organization for Standardization for nickel titanium shape memory alloy wires used in surgical implants. It puts forward strict requirements in terms of chemical composition, physical properties, mechanical properties, etc., similar to national standards, but there may be differences in certain indicators to adapt to the needs and application scenarios of different regions around the world.

Industry standards

YY/T 0713-2009 "Nickel titanium shape memory alloy wires for orthodontic and surgical use in dentistry": This standard specifies the requirements for nickel titanium shape memory alloy wires for orthodontic and surgical use in dentistry. There are clear regulations on the dimensional accuracy, mechanical properties (such as elastic modulus, yield strength, etc.), shape memory performance, and surface quality of alloy wires to meet the special needs of the field of dentistry, such as applying appropriate orthodontic forces to teeth during orthodontic treatment.

Other standards

ASTM F2063-18《Standard Specification for Nickel-Titanium Shape Memory Alloys for Medical Applications》： This is a standard developed by the American Society for Testing and Materials (ASTM) for nickel titanium shape memory alloys used in medical applications. The standard covers requirements for the chemical composition, mechanical properties, physical properties, biocompatibility, and other aspects of alloys, providing specifications for the use of nickel titanium alloy wires in the medical industry in the United States and other regions around the world.

The requirements for nickel titanium alloy wire may vary in different application fields and products, and may also involve other standards and specifications related to nickel titanium alloy wire testing, packaging, transportation, etc. These standards together form a complete system to ensure that the quality and performance of nickel titanium alloy wire meet the requirements of various application scenarios.
