Ni-ti shape memory alloy for medical devices and surgical implants

Ni-ti shape memory alloy for medical devices and surgical implants GB 24267-2009

Nickel titanium alloy is a kind of shape memory alloy, shape memory alloy is a special alloy that can automatically restore its plastic deformation to the original shape at a certain temperature, and has good plasticity

Nickel titanium alloy materials overview
Its expansion rate is more than 20%, the fatigue life is up to 1*10 ^ 7, the damping characteristics are 10 times higher than the ordinary spring, its corrosion resistance is better than the best medical stainless steel, so it can meet all kinds of engineering and medical application needs, is a very excellent functional material.
In addition to the unique shape memory function, memory alloys also have excellent characteristics such as wear resistance, corrosion resistance, high damping and super elasticity.

GB 24267-2009 is the Chinese national standard, the full name of "Medical devices and surgical implants for Nickel-titanium shape memory alloy processing materials". The standard specifies the technical requirements, test methods, inspection rules, marking, packaging, transportation and storage of nickel-titanium shape memory alloy processing materials for medical devices and surgical implants.

Scope of application:

This standard applies to nickel-titanium shape memory alloy processing materials for the manufacture of medical devices and surgical implants, including plates, strips, bars, wires, etc.

 

Material requirements:

The chemical composition of nickel-titanium shape memory alloy should meet the requirements of the standard, usually nickel and titanium as the main components, can also contain a small amount of other elements to improve performance.

The shape memory effect, superelasticity and mechanical properties of the material should meet the requirements of the standard.

 

Processing requirements:

The surface quality, dimensional tolerances, shape and position tolerances of the material to be machined shall meet the requirements of the standard.

The material should be free of cracks, folds, bubbles and other defects.

 

Test method:

The standard specifies the test methods for chemical composition analysis, mechanical properties test, shape memory effect test and hyperelasticity test.

Also includes metallographic inspection, surface quality inspection, etc.

 

Inspection rules:

The sampling method, inspection items and rules of conformity determination of materials are specified.

Each batch of materials is inspected before leaving the factory.

 

Marking, packaging, transportation and storage:

Materials should be clearly marked, including material grade, specification, batch number and other information.

 

The importance:

GB 24267-2009 provides the technical basis for the production and quality control of nickel-titanium shape memory alloy processing materials for medical devices and surgical implants, ensuring the safety and reliability of materials and safeguarding the health and safety of patients.

Packaging should protect materials from damage during transportation and storage.

Materials should be stored in a dry and ventilated environment to avoid corrosion.

Application field:
This standard applies to Ni-Ti shape memory alloy processing materials for the manufacture of medical devices and surgical implants, such as cardiovascular stents, orthopedic implants, dental instruments, etc. Due to their unique shape memory effects and superelasticity, these materials have broad application prospects in the medical field.
