1. Raw material preparation
The production of titanium wire begins with high-purity sponge titanium or titanium ingots. Sponge titanium is a porous material made by extracting and reducing titanium ores such as rutile or ilmenite. These materials are smelted into titanium ingots and used as raw materials for subsequent processing.
2. Titanium ingot smelting
In order to improve the purity and performance of titanium, a vacuum consumable arc furnace (VAR) or plasma arc furnace is usually used for smelting. The smelting process needs to be carried out under high vacuum or inert gas protection (such as argon) to prevent titanium from reacting with active gases such as oxygen and nitrogen.
3. Hot working
The melted titanium ingot is heated to a high temperature for hot working, such as forging, rolling or extrusion. This process forms the titanium ingot into larger bars or plates and gradually changes its shape for subsequent wire processing.
4. Rolling or extrusion of titanium rods
The titanium rods that have undergone preliminary hot working are further reduced in diameter through hot rolling or extrusion processes to form smaller-sized rods or wire blanks. This process helps to improve the density and uniformity of the material.
5. Cold drawing process
Cold drawing is a key step in titanium wire production. The hot-worked Titanium Rod is further stretched and the diameter is reduced through multiple drawing passes until the required titanium wire specifications are reached. After each drawing, the diameter of the titanium rod decreases, the length increases, and the strength and hardness of the material increase. 6. Intermediate annealing
During the cold drawing process, the plasticity of titanium decreases, so intermediate annealing is required regularly. Annealing is to heat the titanium material in a vacuum or inert atmosphere to restore its plasticity, reduce stress, and improve the grain structure for further drawing.
7. Surface treatment
Throughout the production process, an oxide layer or other impurities may form on the surface of the titanium material. To improve the quality of the titanium wire, surface treatment such as pickling or mechanical polishing is usually required to remove surface oxides and impurities to ensure that the final product has a good surface quality.
8. Fine drawing
After a series of cold drawing and annealing, the titanium wire close to the final size will be finely drawn to achieve the precise diameter and tolerance range required by the customer. This step usually requires higher precision drawing equipment and more detailed process control.
9. Final heat treatment
To ensure that the mechanical properties and microstructure of the titanium wire meet the requirements, a final heat treatment may be performed. This step can further improve the toughness, strength and corrosion resistance of the material.
10. Testing and packaging
After production, the titanium wire needs to undergo a series of tests, such as dimensional measurement, tensile testing, surface quality inspection, etc., to ensure that the quality of the product meets the standards. Qualified titanium wire will eventually be wound into coils or cut into fixed lengths for packaging, and then sent to customers for use.
Through these steps, the mechanical properties, corrosion resistance and surface quality of titanium wire are fully guaranteed, and it is widely used in high-end fields such as aerospace, medical equipment, and chemical equipment.
Types of titanium wire
According to the different properties of titanium and titanium alloys, titanium wires with different requirements can be prepared. They are generally divided into Pure Titanium Wire, Titanium Alloy wire, pure titanium eyeglass wire, titanium straight wire, titanium welding wire, titanium hanging wire, titanium coiled wire, titanium bright wire, medical titanium wire, titanium nickel alloy wire, etc. Different types of titanium wires have different uses. For example, pure titanium eyeglass wire is mainly used to make eyeglass frames, titanium hanging wire is used to hang heavy objects, and titanium nickel alloy wire is often used as memory alloy material.
