Therefore, the specific strength (strength/density) of titanium alloy is much higher than that of other metal structural materials, as shown in Table 7-1. It can produce components with high unit strength, good rigidity and light weight. At present, titanium alloy is used for engine components, skeleton, skin, fasteners and landing gear. High thermal strength The use temperature is several hundred degrees higher than aluminum alloy, can still maintain the required strength at moderate temperature, can work for a long time at 450500 temperature these two titanium alloys still have high specific strength in the range of 150500, and aluminum alloy at 150 than the strength decreased significantly. Titanium alloys operate at temperatures up to 500, while aluminum alloys operate below 200. Good resistance to corrosion The corrosion resistance of titanium alloy is much better than that of stainless steel when working in humid atmosphere and seawater medium. Resistance to pitting corrosion, acid corrosion, stress corrosion is particularly strong; Excellent corrosion resistance to alkali, chloride, chlorine organic articles, nitric acid, sulfuric acid and so on. But titanium has poor corrosion resistance to reducing oxygen and chromite medium. Good low temperature performance Titanium alloy can keep its mechanical properties at low temperature and ultra low temperature. Titanium alloys with good low temperature performance and very low gap elements, such as TA7, can maintain certain plasticity at -253. Therefore, titanium alloy is also an important low temperature structural material.

Its disadvantage is low strength at room temperature. It is usually used as heat-resistant and corrosion-resistant materials. α Alloys can usually be divided into complete alloys α Alloy (Gr7), near α Alloy (ti-8al-1mo-1v) and alloy with a small amount of compounds α Alloy (Ti-2.5Cu). 2. ( α+β) Stability of alloy containing a certain amount α Phase harmony β Phase elements, and the microstructure of the alloy in equilibrium is α Phase harmony β Phase. ( α+β) The alloy has medium strength and can be strengthened by heat treatment, but its weldability is poor. ( α+ β) Alloys are widely used, and the output of Ti-6Al-4V Alloy accounts for more than half of all titanium materials. 3. β The alloy contains a large amount of stable β Phase elements can be used at high temperature β All phases were retained to room temperature. β Alloys can usually be divided into heat treatable alloys β Alloy (metastable) β Alloy and near metastable β Alloy) and thermal stability β Alloy. Heat treatable β The alloy has excellent plasticity in quenched state, and the tensile strength can reach 130 ~ 140kgf / mm2 by aging treatment. β Alloys are usually used as high strength and high toughness materials. The disadvantages are large ratio, high cost, poor welding performance and difficult machining.

Test Certificate Mill Test Certificate EN 10204/3.1,TPI Report, EN10204/3.2 Precautions for titanium pipe processing: During the deformation process, titanium pipe will gradually reduce wall and diameter with the rotation and feeding of the rolling mill. The pipe size required by the process can be obtained only after 5 ~ 10 rolling and finishing in one rolling pass. The cold rolling pipe mill can carry out large diameter reduction and wall reduction, but the dimensional accuracy is low after rolling, and the pipe end is prone to cracking, uneven concave convex and other phenomena. The cracking phenomenon can be solved mainly by grinding and leveling before pipe blank processing; For the uneven pipe end, similar to the "fish mouth" phenomenon, flat head treatment is required in the subsequent processing process, otherwise it will cause the plug stuffy accident. Therefore, this paper analyzes from the aspects of process, tooling and equipment, in order to find out the causes of uneven concave convex of pipe end and take effective measures to solve it.

Titanium jigs for plating Any project to anodize requires a reliable hanger/jig/rack, first to prevent it from falling to the bottom of the anodizing tank, and second to allow the current to be safely transferred from the jig to the workpiece. Anodic oxidation clamps are usually made of aluminum or titanium. Aluminum fixtures must of course be anodized and must be chemically stripped. Continuous anodizing and stripping can result in short service life, so there is no need to strip titanium after the anodizing process.

Product Name: Pure titanium jigs For Electroplating Material: Gr1, Gr2 Application: Electroplating, anodizing etc. Size: Customized Surface: Polished Pure titanium jigs For Electroplating Titanium fixtures and racks are mainly used in electroplating, anodizing and other industries. Anodizing fixtures are usually made of aluminum or titanium. The aluminum fixture is anodized after being used for a period of time and must be chemically cleaned. Continuous anodizing and stripping lead to short service life. Therefore, the titanium that does not need to be stripped after anodizing is used. Titanium has been widely used in a large number of applications. Advantages of titanium jigs : ● titanium jigs, consistent from operation to operation. ● titanium fixtures and racks are not anodized like aluminum racks. Therefore, you can use your rectifier anodized parts instead of the rack. ● the high initial cost of titanium jig is offset by the advantages of titanium process savings, better consistency and longer service life.
