The difference between pure titanium screws and titanium alloy screws

When customized a screw, the screw manufacturer needs to determine which material screw fasteners the user needs to produce. There’re many materials that can produce screws. Such as titanium screw, titanium screw are divided into pure titanium screws and titanium alloy screws. Although there seem to be only two options available, there’re different. So what’s the different between pure titanium screws and titanium alloy screws.

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

Titanium screws, pure titanium is a chemical element, chemical symbol Ti, atomic number 21, appearance of steel, have a shiny silver-white. Pure titanium screws have high strength, low density, high hardness, high melting point, and strong corrosion resistance. Due to their stable chemical properties, excellent high temperature resistance and low resistance, strong acid resistance and alkali resistance, high strength etc it’s called “space metal”. High pure titanium screw also have good plasticity.

Titanium alloy refers to an alloy composed of other elements added on the basis of titanium,wherein titanium alloy has 70 kinds of titanium-containing metals such as titanium aluminum alloy, titanium copper alloy, titanium manganese alloy etc. The sensity of titanium alloy is generally about 4.51g/cm³, which is only 60% of that of steel. Some high strength titanium alloy exceed the strength of many alloy structural steels. Therefore, the specific strength (strength/density) of titanium alloys is much larger than that of other metal structural materials, and components with high unit strength, good rigidity, and light weight can be produced. Titanium alloys are used in the aircraft’s engine components, skeletons, skins, fasteners, and landing gear etc.

So when we customized the titanium screws, how to we choose the material of the screw? Pure titanium or titanium alloy? In fact, titanium alloys are produced to cater to the different needs of the industry. Due to the different environment in which all screws are used in the world, the positions of various parts used in the machine parts are also different, and the required screw hardness, flexibility, thermal conductivity, and abrasion resistance of the machines are also different. Therefore, when our screw manufacturers custom produce screw fasteners for customers, we will ask the user what the screws are used in and what kind of performance they need. If hardness is required, titanium cobalt alloys are recommended. Titanium cobalt alloys are generally used. In making cutting tools.

When selecting material for screws, it’s important to understand that when the screws are very hard, their screws will break easily. If you need to customize a wear resistance screw fastener with good hardness, then SHI SHI TONG SCREWS are recommended to use titanium copper alloy. Because copper is one of the wear resistance metals, if titanium screws are both hard-wearing and flexible at the same time as wear-resistance, titanium metal is added because of its hardness, oxidation resistance, corrosion resistance, and coldness. Many advantages such as slow heat conduction, of course, the price is not cheap, if you must take into account the slow heat conduction, light weight, good flexibility, resistance to deep drawing, oxidation resistance, corrosion resistance, no doubt titanium is the first choice, if the general screw fasteners, Choose cheap copper and iron stainless steel and other materials on it. If it is a special environment that requires screw fasteners to have certain alloy characteristics, then it must choose a certain characteristic of titanium alloy metal.
