How To Distinguish The Combination Screw
When customizing screws, screw manufacturers need to determine what kind of screw fasteners the user needs to produce. There are many raw materials that can be used to produce screws. Take the combination screw as an example. The combination screw is divided into pure titanium and titanium alloy. Although it seems that there are only two options, but these two screw raw materials have great knowledge. Let's take a look at the difference between a combination screw and a titanium alloy screw:
Combination screw, pure titanium is a chemical element, chemical symbol Ti, atomic number 22, looks like steel, with silvery white luster, is a transition metal, combination screw has high strength, low density, high hardness, high melting point, anti- It is very corrosive; due to its stable chemical properties, excellent high temperature resistance, low temperature resistance, strong acid resistance, strong alkali resistance, as well as high strength and low density, it is called "space metal". plasticity.
There is a lot of knowledge in titanium alloy screws. Titanium alloy refers to an alloy composed of other elements based on titanium. Among them, titanium alloy has 70 kinds of titanium-containing elements such as titanium-aluminum alloy, titanium-copper alloy, and titanium-manganese alloy. Metal. The density of titanium alloys is generally around 4.51g/cm3, 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 that of other metal structural materials, and parts with high unit strength, good rigidity and light weight can be produced. Titanium alloys are used in aircraft engine components, skeletons, skins, fasteners and landing gear.
So when we customize the combination screws, how should we choose the raw materials of the screws? In fact, titanium alloys are produced to meet the different needs of the industry. Since all the screws in the world are used in different environments, the positions used on machine parts are also different, and the screw hardness, flexibility, heat conductivity and wear resistance required by the machine are also different. Therefore, when our screw manufacturers customize the production of screw fasteners for customers, they will ask the user where the screws are used and what functions are required. If the hardness is required, then the use of titanium-cobalt alloys is recommended. Titanium-cobalt alloys are generally used for making knives.

When selecting screw materials, you must understand that when the hardness of the screw is very high, the screw will easily break. If you need to customize screw fasteners with wear resistance and good hardness, then Shishitong screws advocate the use of titanium-copper alloys. Since copper is one of the wear-resistant metals, if you want to combine screws with more hardness and flexibility while taking into account wear-resistance, titanium metal should be added, because titanium metal has hardness, oxidation resistance, corrosion resistance, cold resistance It has many advantages such as slow heat conduction, and of course the price is not cheap. If it is necessary to take into account the slow heat and cold conduction, light weight, good flexibility, strong drawing resistance, oxidation resistance and corrosion resistance, titanium is undoubtedly the first choice. If it is a general screw fastener, It is enough to choose cheap copper, iron, stainless steel and other materials. If it is really necessary to require screw fasteners to have the characteristics of a certain alloy in a special environment, it is necessary to choose a titanium alloy metal with a certain characteristic. There is too much knowledge in this area.
