Titanium Alloy Screw

What is the difference between pure titanium screw and titanium alloy screw

      When customizing screws, the screw manufacturer needs to determine which kind of screw fasteners the user needs to produce. There are many materials that can produce screws. For example, titanium screws are divided into pure titanium and titanium alloy. Although it seems that there are only two kinds of screw materials to choose from, there are some questions about these two screw materials. Let's follow the Xiaobian to see what is the difference between pure titanium screw and titanium alloy screw:

      Titanium screw, pure titanium is a chemical element, chemical symbol Ti, atomic number 22, the appearance of steel, silver luster, is a transition metal, pure titanium screw strength, low density, high hardness, high melting point, corrosion resistance is strong; Due to its stable chemical properties, good resistance to high temperature and low temperature, strong acid and alkali resistance, as well as high strength, low density, it is called "space metal" high purity titanium screw also has good plasticity.

       Titanium alloy screw there is a lot of knowledge, titanium alloy is based on titanium to add other elements of the alloy, titanium alloy and titanium aluminum alloy, titanium copper alloy, titanium manganese alloy and other 70 kinds of metal containing titanium elements. The density of titanium alloys is generally about 4.51g/ cubic centimeter, which is only 60% of that of steel, and some high-strength titanium alloys exceed the strength of many alloy structural steels. Therefore, the specific strength (strength/density) of titanium alloy is much greater than other metal structure materials, which can be produced with high unit strength, good rigidity and light weight parts. Aircraft use titanium for engine components, skeleton, skin, fasteners and landing gear.

So when we customize titanium screws, how to choose the material of the screw? In fact, titanium alloy is produced to meet the different needs of the industry. Due to the different use environment of all screws in the world, the positions used in the machine parts are also different, the machine requires the screw hardness, flexibility, heat conduction, wear resistance is also different. So our screw manufacturers in the custom production of screw fasteners to customers, will ask the user to use the screw in what aspect. What kind of performance is needed? If hardness is required, it is recommended to use titanium cobalt alloy. Titanium cobalt alloy is generally used to make cutting tools. When selecting screw materials, it is necessary to understand that when the hardness of the screw is very high, then the screw is easy to break. If you need to customize wear and hardness of very good screw fasteners, then it is recommended to use titanium copper alloy. Because copper is one of wear-resistant metal, but if you want to titanium screw in both wear more hardness and flexibility at the same time, will join titanium, because titanium metal have the hardness, anti oxidation and corrosion degrees, cold heat conduction slow, such as a lot of advantages, of course the price is not cheap, if must give attention to both cold and heat conduction slow, light weight, good flexibility and strong drawing resistance, oxidation resistance, corrosion resistance, Undoubtedly titanium is the first choice, if the general screw fastener, choose cheap copper, iron, stainless steel and other materials can be, if it is a special environment must be required to have a certain alloy characteristics of the screw fastener, it must choose a certain characteristics of titanium alloy metal, this aspect of knowledge is too much.
