introduction
Titanium is characterized by light weight, high strength, metallic luster, and good corrosion resistance. Due to its stable chemical properties, it has good resistance to high temperatures, low temperatures, strong acids, and strong alkali, as well as high strength and low density. It is called "space metal", "smart metal", "biological metal" and "omnipotent metal".
Titanium wire classification: titanium alloy wire, pure titanium glasses wire, titanium straight wire, pure titanium wire, titanium welding wire, titanium hanging wire, titanium coiled wire, titanium bright wire, medical titanium wire, titanium-nickel alloy wire.
Titanium wire specifications:
A. Titanium wire specifications: φ0.8-φ6.0mm
B. Titanium wire specifications for glasses: φ1.0-φ6.0mm special titanium wire
C. Titanium wire specifications: φ0.2-φ8.0mm for hanging fixtures
application
The main uses of titanium wire include: welding wire, production of springs, rivets, etc. Widely used in aviation, marine, petrochemical, pharmaceutical and other fields.
1. Welding wire. Currently, more than 80% of titanium and titanium alloy wires are used as welding wires. For example, welding of various titanium equipment, welded pipes, repair welding of aviation jet engine turbine disks and blades, welding of casings, etc.
2. Due to its excellent corrosion resistance, titanium is widely used in chemical, pharmaceutical, papermaking and other industries. For example, Tianjin Chemical Plant uses 3.2mm pure titanium wire to prepare a filter.
3. Titanium and titanium alloy wires are used to manufacture fasteners, load-bearing components, springs, etc. due to their good comprehensive properties. For example, Xi'an High Pressure Valve Factory uses TC4 wire to make valve compression springs.
4. In the medical and health industry, titanium and titanium alloy wires are used to manufacture medical devices, implant crown fixation, skull fixation, etc.
5. Some titanium alloys are used to make satellite antennas and shoulder pads for clothes because of their shape memory function.
6. In the electroplating and water treatment industries, titanium and titanium alloy wires are used to make various electrodes.
titanium wire and titanium alloy wire drawing
Titanium wire and titanium alloy wire drawing is a metal plastic processing process in which the wire rod or wire blank is pulled out from the die hole of the wire drawing die under the action of the drawing force to produce small-section titanium and titanium alloy wire. Wires with different cross-sectional shapes and sizes of various metals and alloys can be produced by drawing. The drawn wire has precise dimensions and smooth surface, and the drawing equipment and mold used are simple and easy to manufacture. When drawing ultra-fine metal wires with a wire diameter less than 0.05mm, it is difficult to pierce the mold. In order to improve the stability of the drawing process, reduce the number of breakage and mold piercing, and improve the drawing production efficiency, the safety factor K value can be greater than 2.0.
Process characteristics: The stress state of metal wire drawing is a three-dimensional principal stress state of two-dimensional compressive stress and one tensile stress. Compared with the principal stress state of compressive stress in three directions, the drawn metal wire is easier to achieve plasticity. deformed state.
The deformation state of drawing is a three-dimensional main deformation state of two directions of compression deformation and one direction of tensile deformation. This state is unfavorable to the plasticity of metal materials and is more likely to produce and expose surface defects. The deformation amount of each pass in the metal wire drawing process is limited by its safety factor. The smaller the deformation amount, the more drawing passes. Therefore, multi-pass continuous high-speed drawing is often used in the production of metal wires.
