Titanium wire is a filamentous material made from titanium and titanium alloys, which has excellent properties such as lightweight, high strength, corrosion resistance, high temperature resistance, and good biocompatibility. It has important applications in many fields. The following is a detailed introduction about titanium wire:

classification

According to material: it can be divided into pure titanium wire and titanium alloy wire. Pure titanium wire has good corrosion resistance and biocompatibility; Titanium alloy wire is further improved in strength, heat resistance, and other properties by adding alloying elements such as aluminum, vanadium, molybdenum, nickel, etc., such as the common TC4 titanium alloy wire.

According to form: it can be divided into titanium wire, titanium straight wire, and wound titanium wire, etc. Different forms of titanium wire are suitable for different processing and application needs.

According to surface condition, it can be divided into pickled surface, shiny surface, and black skin surface. The acid washed surface has undergone acid washing treatment to remove impurities such as oxide scale and improve surface quality; The glossy surface has undergone special treatment, resulting in high smoothness and glossiness; The black skin surface retains the black oxide layer formed during the titanium wire processing, which can provide certain protection in certain specific environments.

Common brand names

The common grades of titanium wire include TA0 in the national standard TA1、TA2、TA3、TA4、TA5、TA6、TA7、TA9、TA10、TA15、TA18、TA19、TC1、TC2、TC3、TC4、TC6、TC11  Different grades of titanium wire have differences in composition, properties, and applications, including Gr1, Gr2, Gr3, Gr5 (Ti-6Al-4V), Ti-6Al-7Nb, Ti-13Nb-13Zr, Ti-15-3-3-3, and others in the American standard.

Production process

Raw material preparation: Select high-quality titanium metal plates or rods as raw materials, and conduct inspection and pretreatment to ensure that the raw material quality meets the requirements.

Smelting: Smelting raw materials under vacuum or inert gas protection to produce titanium ingots, ensuring the purity and quality of titanium.

Forging: Forging titanium ingots to improve their microstructure, increase the density and mechanical properties of the material.

Drawing: Heating the forged billet and using a drawing machine to draw it into slender titanium wire. During the drawing process, it is necessary to control parameters such as heating temperature, tension, and drawing speed to ensure the dimensional accuracy and surface quality of the titanium wire.

Surface treatment: In order to improve the corrosion resistance, wear resistance, and aesthetics of titanium wire, surface treatment is often carried out, such as acid washing, polishing, anodizing, electroplating, and other processes.

Testing: Strict testing is carried out on the produced titanium wire, including appearance quality inspection, dimensional accuracy measurement, chemical composition analysis, mechanical performance testing, etc., to ensure that the product meets relevant standards and customer requirements.
