When your project demands a material that won't corrode, won't weigh you down, and won't compromise on structural integrity, standard steel or aluminum simply fall short. Engineers, hobbyist machinists, and aerospace fabricators working with demanding environments need a titanium sheet they can cut, form, and trust — in exactly the size and thickness they require.
This listing covers TC4 (Grade 5, Ti-6Al-4V) and TA2 (Grade 2, commercially pure) titanium flat sheet, plate, and foil stock. Thickness ranges from 0.1 mm (≈ 0.004 in) up to 4 mm (≈ 0.157 in), with planar dimensions spanning 100 × 100 mm (≈ 3.94 × 3.94 in) through 200 × 500 mm (≈ 7.87 × 19.69 in). Each piece is supplied in a flat, mill-finished condition ready for further processing.
Typical applications include titanium sheet for custom knife blanks and blade stock, lightweight structural brackets for RC aircraft and drone frames, corrosion-resistant shim stock and gasket blanks for marine hardware, heat-shield panels in motorsport and exhaust fabrication, and precision test coupons for welding procedure qualification. The combination of TC4 alloy strength and TA2 weldability makes this range a versatile titanium metalworking sheet for both prototyping and short-run production.

TC4 (Ti-6Al-4V, Grade 5) is an alpha-beta alloy with significantly higher tensile strength (typically 895–1000 MPa) and better fatigue resistance, making it the right choice for structural brackets, knife blanks, and load-bearing components. TA2 (Grade 2, commercially pure) is softer, more ductile, and far easier to TIG weld and cold-form, so it is preferred for corrosion-resistant shims, gaskets, and welded assemblies where strength is secondary to workability.
For foil and shim applications (gaskets, heat shields, shimming) choose 0.1–0.3 mm. For sheet metal work such as brackets, enclosures, and formed parts, 0.5–1.5 mm is the most common range. For structural plate, knife blanks, and machined components requiring rigidity, 2–4 mm is appropriate. If you are unsure, select the variant options on this page to compare sizes and prices, or contact us to confirm suitability.
Yes. Both TC4 and TA2 titanium sheet can be processed by waterjet cutting across all thicknesses listed. Fiber laser cutting works well up to approximately 2–3 mm; thicker sections (3.5–4 mm) are more efficiently cut by waterjet or plasma. Always use inert gas assist (argon or nitrogen) when laser cutting titanium to prevent oxidation of the cut edge.
Yes — titanium is one of the most corrosion-resistant structural metals available. Both TC4 and TA2 grades form a passive titanium dioxide surface layer that resists seawater, dilute acids, and most oxidising chemicals without any additional coating. This makes them well-suited for marine hardware, chemical processing fixtures, and outdoor architectural applications.
TA2 (Grade 2) is the more weld-friendly option and can be TIG welded with standard equipment, provided you use a proper argon back-purge and trailing shield to prevent oxygen contamination. TC4 is weldable but requires more careful heat management and ideally a post-weld stress relief. Both grades should be thoroughly cleaned and degreased before welding. A glove box or welding tent with argon purge is strongly recommended for clean, porosity-free welds.
Order the smallest standard blank that fully contains your finished part outline, leaving at least 5–10 mm of margin on each edge for clamping and cut-off. For example, if your finished part is 85 × 85 mm, the 100 × 100 mm blank is the most economical choice. For elongated parts up to 190 × 290 mm, the 200 × 300 mm format is ideal. All blanks are supplied flat and square, ready for direct layout and cutting.
TC4 (Grade 5) at 2–4 mm thickness is a popular choice for titanium knife handles, liners, and frame-lock scales due to its strength and machinability. For blade stock, note that commercially pure titanium and TC4 do not harden to the same edge-holding level as tool steel; they are more commonly used for non-cutting structural knife components. If you need a cutting edge, consider using titanium for the handle and a steel insert for the blade.
