Difference between pure titanium screw and titanium alloy screw

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

When customizing titanium screws, the screw manufacturer must determine the type of screw fastener that the user must manufacture. There are many materials that can be used to make screws. Take the titanium screws that are split into pure titanium and titanium alloy. There seem to be only two options, but both screw materials have college issues. Follow the analysis of the PTJ Hardware screw manufacturer.

Titanium screw, pure titanium is a transition metal with a silver-white luster that looks like a chemical element, chemical symbol Ti, atomic number 22, steel. Pure titanium screw has high strength, low density, high hardness, high melting point, high corrosion resistance, and is called chemically stable heat resistance, low temperature resistance, acid resistance, alkali resistance, high strength, low density. .. “Space metal” and high-purity titanium screws also have good plasticity.

Titanium alloy screws have a lot of knowledge, titanium alloys refer to alloys of other elements added based on titanium, titanium alloys are 70 kinds such as titanium aluminum alloys, titanium copper alloys, titanium manganese alloys, etc. Contains titanium-containing metals. The density of titanium alloys is generally about 4.51 g / cm 3, which is only 60% of steel. Some high-strength titanium alloys exceed the strength of many alloy structural steels. Therefore, the specific strength (strength / density) of the titanium alloy is much larger than the specific strength of other metal structural materials, and it is possible to manufacture a part having high unit strength, high rigidity, and light weight. Titanium alloys are used in aircraft engine parts, boring, leather, fasteners and landing gear.

Then, when customizing a titanium screw, how do you choose the material for the screw? In fact, titanium alloys are manufactured to meet the different needs of the industry. Due to the different environments in which all screws are used around the world, the placement of the different parts used in mechanical parts is different, and the hardness, flexibility, thermal conductivity and wear resistance of the screws are also different. Therefore, when a screw manufacturer customizes a screw fastener for a customer, the user is asked where to use the screw. What kind of performance do you need? If hardness is required, it is recommended to use titanium cobalt alloy for PTJ screws. Titanium-cobalt alloys are commonly used in the manufacture of cutting tools.

When choosing a screw material, be aware that the screw is prone to breakage if the screw is hard..

If you need to customize a screw fastener with excellent wear resistance and hardness, we recommend titanium-copper alloy. Since copper is one of the abrasion resistant metals, if the titanium screw has both abrasion resistance and bending resistance, the titanium metal must be added. Titanium is not cheap because it has many advantages such as hardness, oxidation resistance, corrosion resistance, low temperature and low temperature conduction. Titanium is arguably the first choice when slow heat and cold conduction, light weight, good flexibility, deep elasticity, oxidation resistance and corrosion resistance need to be considered.
For regular screw fasteners, choose materials such as cheap copper and iron stainless steel. If under special circumstances a threaded fastener is required to have certain alloying properties, a titanium alloy must be selected to obtain certain properties. There is a lot of knowledge in this area.
