Production Introduction
Introduction to titanium
Titanium alloys are alloys that contain a mixture of titanium and other chemical elements. Such alloys have very high tensile strength and toughness (even at extreme temperatures). They are light in weight, have extraordinary corrosion resistance and the ability to withstand extreme temperatures. However, the high cost of both raw materials and processing limit their use to military applications, aircraft, spacecraft, bicycles, medical devices, jewelry, highly stressed components such as connecting rods on expensive sports cars and some premium sports equipment and consumer electronics.

Heat treatment process of titanium hexagonal bar
The heat treatment process of titanium alloy can be summarized as follows:
(1) Stress relief annealing: the purpose is to eliminate or reduce the residual stress generated during processing. Prevent chemical erosion and reduce deformation in some corrosive environments.
(2) Complete annealing: the purpose is to obtain good toughness, improve machinability, facilitate reprocessing and improve the stability of size and structure.
(3) Solution treatment and aging: the purpose is to improve its strength, α Titanium alloy and stable β Titanium alloy can not be strengthened by heat treatment, but only annealed in production. α+β Titanium alloys and contain a small amount of α Metastable phase β Titanium alloy can be further strengthened by solution treatment and aging.
In addition, in order to meet the special requirements of workpieces, double annealing, isothermal annealing β Metal heat treatment processes such as heat treatment and thermomechanical treatment.
Application of Titanium Hexagon hex Bar
1. Aerospace applications due to its light weight and high temperature resistance, it provides a variety of aircraft grade titanium alloys for the U.S. aerospace industry to manufacture aircraft turbine disks, blades and fuselage structural components.
2. Petrochemical uses Petrochemical titanium. Due to its high level of corrosion resistance and heat resistance, titanium raw materials are commonly used in heat exchangers and reactors in the petrochemical industry.
3. Medical application medical grade titanium. Titanium implants are ideal materials for medical devices because of their biocompatibility with human bones and tissues. Titanium suppliers usually provide an inventory of dental implants, prostheses, and bone and joint replacement procedures.
4. Entertainment uses titanium uses, titanium alloy titanium distributors are rapidly discovering a wider range of uses of titanium tubes in entertainment products, including sports equipment such as bicycles, golf clubs and tennis rackets.
5. Titanium sheet metal and wire for decoration and beautification have become attractive substitutes for other special metals used in the jewelry industry, especially wedding jewelry.
