Gr5 titanium bar, also known as Ti-6Al-4V, is one of the most widely used titanium alloys due to its excellent combination of high strength, good corrosion resistance, and low density. As a reliable supplier of Gr5 titanium bar, I am often asked about the available sizes. In this blog post, I will provide detailed information on the various sizes of Gr5 titanium bar that we can offer.
Standard Sizes
We stock a wide range of standard sizes of Gr5 titanium bar to meet the diverse needs of our customers. These standard sizes are commonly used in many industries, including aerospace, medical, automotive, and marine.
Diameter Sizes
For round Gr5 titanium bars, the diameters typically range from 6mm to 300mm. The smaller diameter bars, such as those in the range of 6mm - 20mm, are often used in precision machining applications, like the production of small medical implants and high - performance automotive components. Medium - diameter bars (20mm - 100mm) are suitable for general engineering purposes, such as structural parts in aerospace and marine equipment. Larger diameter bars (100mm - 300mm) are used in heavy - duty applications, for example, in the manufacturing of large - scale aerospace engine components.
Length Sizes
The standard lengths of our Gr5 titanium bars usually range from 1m to 6m. Shorter lengths, around 1m - 2m, are convenient for small - scale projects or for customers who need to do further cutting and processing. Longer lengths, up to 6m, are preferred by customers who require continuous bars for large - scale manufacturing, such as in the construction of long - span aerospace structures or large - sized marine vessels.
Custom - Made Sizes
In addition to the standard sizes, we also offer custom - made Gr5 titanium bars to meet specific customer requirements. Our advanced manufacturing facilities and experienced technical team enable us to produce bars with non - standard diameters and lengths.
Custom Diameters
If you need a Gr5 titanium bar with a diameter that is not in our standard range, we can manufacture it for you. Whether it is a very small diameter for micro - machining applications or an extremely large diameter for special industrial projects, we have the capabilities to produce it. Our production process ensures high precision in diameter control, with a tolerance that can be as low as ±0.05mm for small - diameter bars and ±0.5mm for large - diameter bars.
Custom Lengths
We understand that some projects may require bars of specific lengths that are not available in our standard offerings. We can produce custom - length bars according to your exact specifications. This is particularly useful for projects where precise length is crucial, such as in the assembly of complex machinery or in the construction of specialized equipment.


Surface Finish and Quality Assurance
Regardless of the size of the Gr5 titanium bar, we pay great attention to the surface finish and quality. Our bars are available with different surface finishes, including mill finish, polished finish, and pickled finish.
Mill Finish
The mill finish is the natural surface finish of the bar after the manufacturing process. It has a relatively rough texture but is suitable for many general applications where surface appearance is not a critical factor.
Polished Finish
A polished finish provides a smooth and shiny surface. It is often required for applications where aesthetics are important, such as in the medical and jewelry industries. Our polishing process can achieve a surface roughness of Ra ≤ 0.8μm, which gives the bar a high - quality appearance.
Pickled Finish
The pickled finish is used to remove any surface contaminants and oxides, resulting in a clean and corrosion - resistant surface. This finish is commonly used in applications where corrosion resistance is of utmost importance, such as in the chemical and marine industries.
We have a strict quality control system in place to ensure that all our Gr5 titanium bars meet the highest quality standards. Each bar undergoes a series of tests, including chemical composition analysis, mechanical property testing, and non - destructive testing. Only bars that pass all the tests are allowed to leave our factory.
Applications of Gr5 Titanium Bars in Different Sizes
The different sizes of Gr5 titanium bars find applications in a wide range of industries:
Aerospace Industry
In the aerospace industry, small - diameter Gr5 titanium bars are used in the production of fasteners, such as bolts and screws, due to their high strength - to - weight ratio. Medium - and large - diameter bars are used in the manufacturing of structural components, engine parts, and landing gear components. For example, large - diameter bars are used to make the shafts of aerospace engines, which need to withstand high - temperature and high - stress conditions.
Medical Industry
Small - diameter Gr5 titanium bars are widely used in the medical field for the production of orthopedic implants, such as bone screws and pins. Their biocompatibility and high strength make them an ideal material for these applications. The custom - made sizes allow for the production of implants that are tailored to the specific needs of patients.
Automotive Industry
In the automotive industry, Gr5 titanium bars are used in high - performance applications. Small - and medium - diameter bars are used to make components such as connecting rods and valve springs. These components benefit from the high strength and low weight of titanium, which can improve the performance and fuel efficiency of the vehicle.
Marine Industry
In the marine industry, Gr5 titanium bars are used in various applications due to their excellent corrosion resistance. Medium - and large - diameter bars are used in the construction of marine structures, such as ship hulls and offshore platforms. The custom - made lengths can be used to create seamless and strong connections in these structures.
