What is the difference between pure titanium screws and titanium alloy screws?

When customizing screws, screw manufacturers need to determine which material of screw fasteners the user is required to produce. There are many materials that can be used to produce screws, take titanium screws for example, titanium screws are divided into pure titanium and titanium alloy. Although it seems that there are only two options, however, these two screw materials but there is a big question. Let's take a look, pure titanium screws and titanium alloy screws have what the difference:
Titanium screws, pure titanium is a chemical element, chemical symbol Ti, atomic number 22, the appearance of steel, with a silvery-white luster, is a transition metal, pure titanium screws, high strength, low density, high hardness, high melting point, corrosion resistance is very strong; due to its stable chemical properties, good resistance to high temperatures, low temperature resistance, resistance to strong acids, resistance to strong alkalis, as well as high strength, low density, called the "space metal". "Space metal" high purity titanium screws also has good plasticity.

Titanium screws which is a great learning, titanium alloy refers to titanium as the basis for the addition of other elements composed of alloys, which titanium alloys and titanium aluminum alloys, titanium copper alloys, titanium manganese alloys, such as 70 kinds of titanium-containing elements of the metal. The density of titanium alloys is generally around 4.51g/cm3, only 60% of steel, some high-strength titanium alloys exceed the strength of many alloy structural steel. Therefore, the specific strength of titanium alloys (strength / density) is much greater than other metal structural materials, can produce unit of high strength, good rigidity, lightweight parts. Aircraft engine components, skeleton, skin, fasteners and landing gear, etc. all use titanium alloy.

So when we customize titanium screws, how to choose the material of the screw, in fact, titanium alloy is to cater to the different needs of the industry. Because all the screws in the world are used in different environments, used in the machine parts on the various positions are different, the machine required screw hardness, flexibility, thermal conductivity, wear resistance is also different. So we screw manufacturers in the custom production of screws to customers fasteners, will ask the user screws used in which, need to have what kind of performance, if the hardness is required then it is recommended that the use of titanium cobalt alloy, titanium cobalt alloy is generally used in the manufacture of cutting edge tools.

In the selection of screws, it must be understood that when the hardness of the screw is very high, then the screw is easy to break. If you need to customize screw fasteners that are wear-resistant and have a good hardness, then Sexton Screws recommends titanium-copper alloy. Because copper is one of the wear-resistant metal, but if you want to titanium screws in both wear-resistant at the same time more hardness and flexibility, we need to join the titanium metal, because titanium has a hardness, oxidation resistance, corrosion resistance, slow heat and cold conduction and many other advantages, of course, the price is not cheap, if you have to take into account the slow heat and cold conduction, lightweight, flexible and good, anti-strength deep drawing, oxidation resistance, corrosion resistance, no doubt titanium is the first choice, if the general Screw fasteners, choose cheap copper, iron, stainless steel and other materials can be, if it is really a special environment must require screw fasteners with a certain alloy characteristics, it is necessary to choose a certain characteristic of titanium alloy metal, this aspect of the study is too much.
