Industry solutions

Aerospace

Large frame components often involve complex loads and require multiple machining steps. Conventional sheet metal cutting not only results in significant material waste but also incurs significant processing costs. Using AMS 4928 Grade 5 titanium flat bar as a near-net-size blank, we can directly saw to an accuracy of ±0.125″.

Typical components: fuselage reinforcement beams, seat rails, satellite load-bearing brackets, and engine support rings.

Medical devices

Implantable parts require low impurities and a high surface finish, but traditional stainless steel plates struggle to achieve both biocompatibility and lightweight performance. Using Grade 23 ELI titanium flat bar, precision milled and polished to Ra ≤ 0.8 µm, we can form high-precision bone plates and surgical fixtures in a single step, reducing the risk of subsequent grinding and sterilization.

Typical components: spinal fixation plate, titanium alloy clamp body, bone connector base.

Offshore Engineering / Desalination

Stainless steel heat exchanger plates and pump casings are prone to pitting corrosion in chloride-containing environments, leading to high downtime and costly replacement. Using Grade 2 pure titanium flat bar to manufacture tube sheets and baffles can provide over 20 years of continuous service in 3.5% NaCl seawater without pitting corrosion, significantly reducing lifecycle costs.

Typical components: multi-stage flash heat exchanger tube sheets, seawater pump casing support frames, condenser baffles.

FAQ

Can titanium flat bar be welded directly to stainless steel or aluminum alloy?

Direct fusion welding of titanium with stainless steel or aluminum can form brittle intermetallic compounds, leading to joint failure. In engineering, titanium-stainless steel (or titanium-aluminum) explosive composite transition joints are commonly used, or mechanical connections using titanium sleeves or bolts under inert protection are performed. If dissimilar material welding is necessary, assess the risk of weld embrittlement and control heat input.

What surface finish grades do you offer?

The standard industrial finish is pickled and passivated (Ra ≈ 3.2 µm). For higher finishes, sandblasting (Ra ≈ 1.6 µm), mechanical polishing (Ra ≤ 0.8 µm), mirror polishing (Ra ≤ 0.2 µm), or anodized finishes are available. Please specify your target Ra value and intended use when inquiring, and we will recommend the most economical processing route.

What is the minimum bend radius of Grade 5 titanium flat bar?

In the annealed state, the recommended minimum internal bend radius for cold bending is 3 x t of the material thickness. If a smaller radius is required, local heating or aging followed by chamfering can be used. Please provide the thickness and bend angle, and we can use FEA to assess formability.

How should titanium flat bar inventory be stored to prevent contamination and oxidation?

It is recommended to store in a dry, chloride-free warehouse at a temperature of 5-30°C and a relative humidity of <60%. Flat bars should be kept in vacuum bags or sealed plastic wrap to avoid direct contact with carbon steel tools to prevent scraping and cross-contamination. For long-term storage, it is recommended to re-inspect the surface condition every 12 months.

Is there a minimum order quantity for custom sizes?

The minimum order quantity (MOQ) for standard Grade 2/5 flat bar cut to length is 10 kg or a single piece (depending on the size). If the size exceeds the existing parent material specifications, new blanks will be required, and the minimum order quantity is typically 50 kg or more. Our sales staff can quickly calculate the optimal procurement plan based on the drawing.

Are there any recommended tools and parameters for titanium flat bar machining?

We recommend using Ti-Al-N coated carbide cutting tools with a 90° entering angle and a 10-15° rake angle. Dry cutting or using a low-chloride water-soluble cutting fluid is acceptable. Line speeds are 40-60 m/min (Grade 2) or 30-50 m/min (Grade 5/23), with a feed rate of 0.05-0.15 mm/rev. To avoid workpiece deformation, use multiple shallow cuts and maintain adequate cooling. A detailed process sheet is available free of charge after placing your order.
