Titanium thickness

Types of titanium thickness

Titanium thickness comes in several types suitable for multiple uses. Titanium grades range from pure, which results in high strength and corrosion resistance, to alloyed grades with iron. The alloys add further enhancements and tolerance to high temperatures. The cold-rolling process produces titanium sheets of differing thicknesses, with each thin sheet demonstrating unique mechanical properties depending on its subsequent thickness. While thin sheets might have applications in less demanding settings, thicker titanium is ideal in industries with high cooling and heating flux, such as astrodynamics and propulsion systems.

Industrial applications of titanium thickness

Titanium metal exhibits unmatched biocompatibility, making it an ideal metal in medicine. Titanium thickness varies for each medical application. For example, 5 mm titanium thickness is required when fabricating artificial joints and dental implants, while smaller cardiovascular devices, such as pacemakers, may have titanium as thin as 0.5 mm.

• Aerospace industry:

  In aerospace, titanium is favored for its strength and resistance to extreme temperatures. It is commonly used in engine components, airframes, and other critical structures. Titanium thickness requirements in aerospace engineering can greatly vary depending on the titanium parts' functional and structural roles. For example, the thicker grades G5, 13, and 18 (0.50-1.5 mm) are ideal for airframe components, while the alloys with lower thicknesses, such as 0.1-0.25 mm G23 and G27, are more suitable for operational sections of engines.

• Chemical processing:

  In the chemical industry, titanium handles corrosive substances, with titanium pumps, valves, and heat exchangers only constructed from titanium. The thickness of titanium used in such sensitive applications varies according to the extent of corrosive exposure and temperature. While standard-grade titanium is often adequate for mild chemicals, more potent acids and alkalis require thicker titanium to ensure long-lasting structural integrity.

• Energy sector:

  In addition, titanium's thickness is crucial in the energy industry, particularly in devices associated with the extraction and processing of oil and gas, as well as in the production of both solar and nuclear energy. Due to its resilience to corrosion and high temperatures, titanium has been selected for well-placed components like heat exchangers, piping, and reactors that operate under extreme conditions.

• Marine applications:

  Lastly, there are also marine applications. In marine environments, where materials suffer from severe saltwater corrosion, titanium is preferred for its unmatched longevity. Desalination plants employ titanium filters and catalysts, which are vital for producing freshwater from seawater. For marine use applications, thickness is often greater due to the high pressure and corrosive nature of seawater. Typically, 6-4 titanium, which consists of 90% titanium, 6% aluminum, and 4% vanadium, is ideal for saltwater exposure.

Product specifications and maintenance of titanium thickness

The properties and maintenance depend on the titanium alloys used and how thick the titanium is for these applications.

• Irrespective of the industry or usage, titanium exhibits high resistance to corrosion due to its formation of a protective oxide layer. Its layer makes titanium ideal for chemical processing and marine environments.
• Maintenance:Maintenance is typically limited to routine cleaning. This is gentle detergent and water to remove any accumulated contaminants from the surface.
• Titanium in the medical field:Often, in the medical field, titanium is exposed to body fluids and must be fully resistant to bio-corrosion. Common thickness grades include titanium 6-4 and titanium 5 mm thickness. The 6-4 alloy, which is 90% titanium, 6% aluminum, and 4% vanadium, provides high strength, which makes it useful for mechanical bone implants, screws, and other load-bearing devices. 6-4 and 5 mm titanium thickness is required in surgical equipment and implants. Maintenance of the 5 mm titanium thickness and 6-4 alloy is crucial since the devices must be sterilized before use and after use to prevent infection. The sterilizing processes apply heat and chemicals that must not affect the titanium's integrity. Spec-wise, the titanium 6-4 alloy has good fatigue resistance and exceptional corrosion-resistant properties due to the fine alpha-beta structure.
• Chemical processing:In chemical processing, titanium is employed to construct reactors, heat exchangers, and other hardware. Typical thicknesses for such items range from 0.5 to 3 mm, depending on the pressure and corrosive ingredients contained therein. Titanium grado 2 and grado 5, which are retarded to abrasion and chemical agents, are commonly found in this industry. Grado 2 titanium is pure commercially and offers superb corrosion resistance to chlorides and acids, while grado 5 beta-stabilized titanium plus alloys offers increased resistance to sulfuric and hydrochloric acids while still retaining some degree of resistance.
• Aerospace Industry:In the aerospace industry, titanium is aeronautical vehicle components's preferred material due to its amazing strength-to-weight ratio and capability to withstand high temperatures. The most popular grades are 6-4 and 5 mm titanium sheets, which are used in airframes, engine components, and other structures. The thickness of titanium in these applications ranges from 0.5 mm to 5 mm, depending on the specific application. Maintenance checks are regularly carried out for wear and tear, and maintenance mainly consists of cleaning and inspections. One unique aspect of aerospace titanium is that its lightweight construction makes it easier to maintain, extends its life, and maximizes performance in crucial environments.
• Marine Applications:For marine applications, thickness frequently exceeds 3 mm, given the demands of high pressure and continuous exposure to the corrosive environment of saltwater. Commonly used titanium alloys in marine hardware are 6-4 and 5 mm. These alloys are exceptional against saltwater-induced corrosion and elemental chloride-induced chemical corrosion. Maintenance of titanium parts in marine settings usually requires periodic cleaning to remove biofouling, such as barnacles and seaweed.
• Energy Sector:In the energy sector, titanium thickness depends on the unique conditions of each application. Examples include oil, gas, nuclear, and solar energy. The most commonly employed thickness levels are typically between 1 mm and 10 mm and are popular for heat exchangers and reactors. Like other industries, corrosion is easily prevented with its built-in resistance, while routine cleaning and inspection are the main maintenance tasks.

How to choose titanium thickness

When purchasing titanium in bulk for any of the aforementioned industrial applications, buyers must consider several quantifiable factors. These factors directly make up these titanium sheets and rods' physical and mechanical properties and functionality.

• Titanium grade:Different titanium alloys have unique compositions, resulting in diverse mechanical and chemical resistance behaviors. Grade 2 titanium is commercially pure with outstanding corrosion resistance for chemical hardware, while grade 5 alloy is ideal for high-stress applications since it is heat treatable and possesses good formability.
• Thickness:The thickness of titanium ranges from thin sheets of 0.5 mm to 10 mm significantly affects several structures. Choosing the correct thickness is critical to guarantee that the titanium structure can resist the mechanical loads and environmental strains contextually pertinent to it. While thinner grades could be adequate for less demanding applications, thicker materials are preferred for high-pressure or high-temperature conditions.
• Surface finish:Surface finish is another factor that affects the material's compatibility in various industries. For example, polished surfaces provide better corrosion resistance in chemical and marine environments and biomimetic applications like medicine. Rough finishes increase adhesion in composite material manufacturing or biomedical implements like bones and dental structures.
• Fabrication and forming:Buyers should consider what equipment might be needed to process the titanium for fabricating components. Titanium alloys, such as grade 5, exhibit good workability when manipulated at room temperature and elevated temperatures. This property makes it moldable into complex shapes for aerospace and medical components. However, some titanium grades are difficult to weld and machine, so the ideal choice would be to consult with the supplier and titaniumworking specialist about forming methods, especially if the components demand tight tolerances and precise dimensions.
• Supplier reliability:Lastly, quality control directly results from the reputation and reliability of the titanium supplier. Reputable suppliers frequently conduct tests on the mechanical properties, corrosion resistance, and other quality-related traits of the titanium alloys they sell. Buyers should also seek suppliers who are willing to provide detailed material test certificates in order to ensure that the material matches specification requirements.
