View Details4mm Titanium Sheet
A medium-gauge titanium sheet that balances structural rigidity with good formability, suitable for a broad spectrum of load-bearing and corrosive service applications.
Product Overview
Bokang's 4mm Titanium Sheet is manufactured using advanced vacuum arc remelting technology, ensuring exceptional purity and consistent mechanical properties.
The 4mm titanium sheet is a robust and versatile semi-structural material, offering a substantial increase in stiffness and load-bearing capacity compared to thinner gauges, while still retaining sufficient ductility for moderate forming operations such as press braking and roll forming.
This thickness is commonly utilized across various grades, including commercially pure titanium (Grades 2, 3) for corrosion-resistant applications, and Grade 5 (Ti-6Al-4V) for components requiring high strength. The 4mm thickness provides a effective barrier in corrosive environments and is thick enough to be machined, threaded, or welded using standard procedures with filler wire. It serves as a workhorse material in industries like chemical processing, marine, and power generation for fabricating tanks, ducting, and structural supports that must withstand aggressive media and mechanical loads.

Key Advantages of Bokang 4mm Titanium Sheet
Discover why our titanium wire stands out in the industry
Structural Integrity
Provides significant resistance to buckling and deflection under load, making it suitable for self-supporting panels, baffles, and structural liners.
Fabrication Versatility
Thick enough for reliable welding and machining, yet formable enough for rolling into cylinders or bending into brackets, offering broad design flexibility.
Long-Term Durability
The 4mm cross-section offers substantial material loss allowance in corrosive environments, extending service life for vessels and piping.

Material Selection Guide
How to choose the right titanium wire for your application
1
Evaluate Load and Pressure Requirements
For pressure vessels or structural parts, perform stress calculations to verify 4mm thickness is adequate. Grade 5 may be necessary for high-pressure applications.
2
Select Grade Based on Corrosion Mechanism
For oxidizing acids (nitric, chromic), commercially pure grades (1,2) excel. For reducing acids or crevice corrosion, consider Grade 12 (Ti-0.3Mo-0.8Ni) or Grade 7 (Pd stabilized).
3
Consider Thermal Effects
If the application involves thermal cycling, ensure the selected grade and thickness can handle the induced thermal stresses without distortion. Grade 2 is often suitable for moderate ranges.
4
Plan for Joining Methods
4mm is well-suited for TIG welding with filler wire. Specify matching filler grade. For bolted connections, ensure edge distance and hole spacing account for titanium's lower bearing strength compared to steel.
Production Process & Quality Control
Our rigorous manufacturing process ensures consistent quality
Slab Heating & Conditioning
A titanium slab of appropriate thickness is heated uniformly to a forging temperature in a controlled atmosphere furnace.
→
Hot Rolling to Transfer Bar
The slab is rolled in a reversing mill to reduce thickness and create a long transfer bar with a refined, uniform grain structure.
→
Finish Hot Rolling
The transfer bar is further hot rolled on a Steckel mill or plate mill to achieve the final 4mm thickness with controlled mechanical properties.
→
Heat Treatment (Annealing)
The sheet is annealed in a batch furnace to achieve the desired combination of strength and ductility, then air-cooled.
→
Descaling & Pickling
The annealed sheet, now with an oxide scale, is grit blasted or chemically descaled, then pickled in a hydrofluoric/nitric acid bath to reveal a clean, metallic surface.
→
Shearing, Inspection, Marking
The continuous sheet is shear-cut to order size, inspected for dimensions and surface defects, and marked with grade and heat number.
Frequently Asked Questions
Common questions about pure titanium wire
Yes, commercially pure grades (1, 2, 3) in annealed condition can be cold bent. The minimum bend radius is typically 2 to 3 times the sheet thickness (8-12mm for 4mm sheet) when bending across the rolling direction. Always refer to the mill's specific data.
Approximately 140 kg (308 lbs). Calculation: Area (1.22m x 2.44m = 2.977 m²) x Thickness (0.004 m) x Density (4500 kg/m³). Grade 5 would be slightly heavier due to alloying.
Yes, 4mm is a very common stock thickness for Ti-6Al-4V (Grade 5) sheet. It is widely used in aerospace frames, marine fittings, and high-performance automotive components where strength is critical.
Plasma cutting (with nitrogen or argon/hydrogen mix), waterjet cutting, and laser cutting are highly effective. Abrasive cutting can be used but generates heat and may leave a heat-affected zone. Shearing is possible but requires significant force and can deform edges.
Fabrication costs are higher due to the need for specialized tooling (non-ferrous), stricter cleaning protocols, and more complex welding procedures requiring inert gas shielding on both sides. However, lifecycle costs can be lower due to titanium's longevity and reduced maintenance.
