Example Embodiment

[0008] The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to make a clearer and clearer definition of the protection scope of the present invention.

[0009] The present invention is a nickel-titanium-based shape memory alloy. The nickel-titanium-based shape memory alloy is composed of six metal components: nickel, titanium, copper, chromium, manganese, and cadmium. The weight percentages of the components in the memory alloy are: the nickel accounts for 60.3%-64.9%, the titanium accounts for 21.4%-22.5%, the copper accounts for 7.4%-8.3%, and the chromium accounts for 2.8%-3.7%, the manganese accounts for 1.9%-2.7%, and the cadmium accounts for 1.6%-2.5%.

[0010] Further, the weight percentage of each component in the nickel-titanium shape memory alloy is specifically: the nickel accounts for 64.3%, the titanium accounts for ...

Abstract

The invention discloses nickel-titanium system shape memory alloy. The nickel-titanium system shape memory alloy is formed by compounding six metal elements of nickel, titanium, copper, chromium, manganese and cadmium. The nickel-titanium system shape memory alloy comprises, by weight, 60.3%-64.9% of nickel, 21.4%-22.5% of titanium, 7.4%-8.3% of copper, 2.8%-3.7% of chromium, 1.9%-2.7% of manganese and 1.6%-2.5% of cadmium. The nickel-titanium system shape memory alloy is composed of the six metal elements of nickel, titanium, copper, chromium, manganese and cadmium and has the advantages that the memory resilence function is achieved, magnetism does not exist, abrasion, corrosion and high temperature are resisted, and toxicity does not exist.

Description

technical field [0001] The invention relates to an alloy, in particular to a nickel-titanium shape memory alloy. Background technique [0002] Shape memory alloy (shape memory alloy) has a wide range of applications in the field of clinical medicine, such as artificial bones, traumatic bone fixation pressurizers, dental orthodontic devices, various types of endovascular stents, embolizers, heart repair devices, thrombus filters , interventional guide wires and surgical sutures, etc., memory alloys are playing an irreplaceable role in modern medicine. Nickel-titanium shape memory alloys are usually used as a mainstream memory alloy. However, with the continuous development of current productivity, the various performances of nickel-titanium shape memory alloys on the market can no longer meet the needs of the current society. Contents of the invention [0003] The object of the present invention is to provide a nickel-titanium series shape memory alloy with memory restorat...
