Abstract

Aiming to solve the problems of over wide elastic stress platform, narrow temperature range generated by super elasticity and overlarge alloy grain of a nickel-titanium binary alloy, the invention provides a titanium-based quinary alloy. The titanium-based quinary alloy comprises the following elements in percentage by weight: 45 to 55 percent of Ni, 1 to 10 percent of Cu, 0.1 to 2 percent of Cr, 0.1 to 2 percent of B, and the balance of Ti and inevitable impurities. The titanium-based quinary alloy material has the advantages of high elastic strain, excellent cold and hot workability, and suitability for the production of an orthopedic wire used for orthodontic treatment; moreover, the produced orthopedic wire is flexible and easily bent.

Description

technical field [0001] The invention relates to an alloy material, in particular to an alloy material which can be used for oral orthodontics. Background technique [0002] Whether the teeth grow neatly not only affects the appearance, but also affects the pronunciation, chewing function and the health of the teeth, and even leads to facial deformities and unnecessary psychological pressure. Orthodontics, in layman's terms, is to arrange the misaligned teeth into order and solve the above-mentioned problems caused by misaligned teeth. Orthodontic treatment technology has been widely used for its short chair-side working time, simple clinical operation and high-quality treatment effect. In orthodontic treatment, the orthodontic wire is the key component of the appliance to generate force, and it plays a decisive role in achieving the best possible occlusal relationship and maintaining stability after healing, as well as increasing the beauty of the face. . [0003] In the ...
