View Details3mm Titanium Sheet
A medium-gauge titanium sheet providing substantial rigidity and load-bearing capacity, suitable for structural panels, machine guards, and heavy-duty fabrications.
Product Overview
Bokang's 3mm Titanium Sheet is manufactured using advanced vacuum arc remelting technology, ensuring exceptional purity and consistent mechanical properties.
3mm titanium sheet occupies a important position as a medium-thickness stock material, offering significantly greater stiffness and strength than 1mm sheet while remaining formable with standard fabrication equipment. At this thickness, the sheet transitions from being primarily a cladding or lining material to a bona fide structural element capable of carrying substantial loads. It is thick enough to be tapped for threads, machined with pockets or features, and welded with standard procedures without excessive concern for burn-through.
This gauge is widely used for fabricating machine guards, covers, and access panels in corrosive environments; as flooring or decking in marine and chemical plants; and as the primary material for brackets, frames, and chassis where corrosion resistance and strength are paramount. Available in both CP grades (for formability and general corrosion resistance) and Grade 5 (for maximum strength), 3mm sheet can be cut via plasma, waterjet, or laser (with appropriate power), and formed on heavy-duty brake presses. Its versatility makes it a workhorse thickness for industrial, marine, and architectural applications demanding durability and longevity.

Key Advantages of Bokang 3mm Titanium Sheet
Discover why our titanium wire stands out in the industry
Ideal Thickness for Machining Features
Provides enough material depth to machine counterbores, pockets, O-ring grooves, and tapped holes directly into the sheet, creating integrated, multi-functional components.
High Load-Bearing Capacity as Plate
Can be used as a flat plate for supporting heavy equipment, as a baseplate for machinery, or as a wear plate, offering strength far exceeding thinner sheets.
Effective Vibration Damping and Sound Deadening
The mass and stiffness of 3mm sheet make it effective at dampening vibrations and reducing noise transmission when used as a panel or barrier.

Material Selection Guide
How to choose the right titanium wire for your application
1
Assess Whether the Application is Truly Structural
If the sheet will be primarily in bending (like a shelf or platform) or shear (like a gusset), 3mm is a good starting point. Use beam or plate bending formulas to calculate deflection and stress. If loads are very high, consider Grade 5 or moving to a thicker plate.
2
Design for Weldability and Distortion Control
3mm thickness allows for full penetration welds with proper edge preparation. However, welding will cause distortion. Design with staggered welds, use strong-backs during welding, and plan for a post-weld straightening operation if flatness is critical.
3
Specify Edge Condition and Flatness Requirements
For safety and appearance, specify that cut edges be deburred. If the sheet will be used as a precision surface (e.g., a mounting plate), specify the required flatness tolerance, which may require additional leveling beyond standard mill flatness.
4
Consider the Use of Stiffeners or Formed Edges
To increase the bending stiffness of a large 3mm panel without adding thickness, design in formed stiffening ribs (beads) or flanged edges. This is an efficient way to create a lightweight, rigid structure from sheet material.
Production Process & Quality Control
Our rigorous manufacturing process ensures consistent quality
Slab Reheating and Breakdown Rolling
A titanium slab is heated and passed through a reversing hot mill to reduce it to a thickness suitable for further rolling, often around 10-15mm.
→
Hot Finishing Rolling
The transfer bar is further hot-rolled on a finishing mill to bring it close to the final 3mm target, accounting for thermal contraction and scale loss.
→
Heat Treatment and Pickling
The hot-rolled coil is annealed to achieve desired properties and then pickled in acid to remove the thick, adherent oxide scale formed during hot rolling.
→
Cold Rolling (Optional for Gauge/Tolerance Control)
For tighter thickness tolerance or a smoother surface, the pickled sheet may be given a light cold-rolling pass (skin pass). For 3mm, this is less common than for thinner sheets, and it may be supplied as hot-rolled and pickled.
→
Leveling and Cutting to Size
The coil or sheet is passed through a leveler to improve flatness, then sheared or saw-cut into standard sheet sizes (e.g., 1500x3000mm).
→
Final Inspection, Marking, and Packaging
Each sheet is inspected for thickness, dimensions, and surface quality. It is marked with grade and heat number, then packaged flat or on edge to prevent damage during shipping.
Frequently Asked Questions
Common questions about pure titanium wire
Yes, but it requires a powerful press brake due to titanium's high strength and springback. Bending 3mm Grade 2 titanium requires roughly 3-4 times the tonnage of bending 3mm mild steel. You must use a V-die width appropriate for the material (typically 6-8 times the thickness, so 18-24mm). Springback is significant, so the tooling must over-bend the part to achieve the desired final angle.
Use a sharp, high-quality cobalt or carbide drill bit with a 118° or 135° split point. Use a low rotational speed (30-50 SFM for Grade 2) and a firm, consistent feed pressure. Apply a generous amount of cutting fluid or paste. Clamp the sheet securely to prevent vibration. Peck drilling (retracting frequently to clear chips) is essential to prevent work hardening and bit breakage.
3mm titanium sheet, especially Grade 5, can provide fragmentation protection against low-velocity shrapnel and some handgun rounds at certain distances and angles. However, for certified ballistic protection against rifles, much thicker or laminated armor systems are required. Titanium's use in armor is due to its high specific ballistic efficiency (performance per weight), not because thin sheets are inherently highly bulletproof.
The total cost is typically 4-8 times higher. Breakdown: Material cost is 5-10x. Cutting cost is ~1.5-2x (slower speeds, more expensive consumables). Forming cost is ~2-3x (higher tonnage, tool wear, springback compensation). Welding cost is ~1.5-2x (specialized shielding, slower travel speeds). The justification must come from the value of corrosion resistance, weight savings, or performance in the application.
Yes, but surface preparation is critical. The standard pickled mill finish provides a good anchor profile. The sheet must be thoroughly cleaned and degreased. A specialized primer or conversion coating designed for titanium is often recommended before powder application to ensure maximum adhesion and prevent under-film corrosion. The curing temperature of the powder must be compatible with titanium's properties (typically below 250°C to avoid excessive oxidation).
