When your project demands a material that won't corrode, won't weigh you down, and won't let you down under stress, standard steel and aluminum often fall short. Engineers, makers, and fabricators who work with aerospace components, marine hardware, medical fixtures, or high-performance DIY builds need a titanium metal plate sheet that delivers consistent purity and dimensional accuracy across every cut.
This listing covers flat titanium sheet and foil stock available in three alloy grades — TA1 (GR1, commercially pure), TA2 (GR2, commercially pure), and TC4 (GR5, Ti-6Al-4V alloy) — with thickness options ranging from 0.8 mm to 20 mm (approximately 0.031" to 0.787"). Each piece is cut to 100 mm × 100 mm (approx. 3.94" × 3.94") as the base size, with additional size and quantity options available via variant selection.
Typical applications include titanium sheet for knife-making blanks and blade stock, lightweight structural panels for RC aircraft and drone frames, corrosion-resistant shim stock for marine and chemical environments, heat shields and exhaust components for motorsport builds, and biocompatible fixture plates for laboratory or medical prototyping.

GR1 (TA1) offers the highest ductility and is easiest to form and weld — ideal for thin foil work, medical fixtures, and chemical processing parts. GR2 (TA2) adds slightly more strength while retaining excellent corrosion resistance, making it the most widely used commercially pure grade for marine and industrial applications. GR5 (TC4 / Ti-6Al-4V) is an alpha-beta alloy with roughly 3× the strength of GR1, suited for aerospace brackets, high-load structural parts, and performance motorsport components where weight savings are critical.
For full-tang knife blanks and blade stock, 3 mm – 5 mm in GR5 (TC4) is the most common range, providing enough material for grinding a bevel while keeping the finished blade lightweight. Thinner sheets (1 mm – 2 mm) work well for liner material or decorative scales. If you are making a heavy chopper or tactical blade, 6 mm – 8 mm GR5 gives additional spine thickness.
Titanium can be cut with standard metalworking tools, but it requires slower feed rates, sharp carbide tooling, and adequate coolant to prevent work-hardening and tool wear. GR1 and GR2 are significantly easier to machine than GR5. For hobby or small-shop use, an angle grinder with a thin cutting disc, a bandsaw with bi-metal blades, or waterjet cutting services are practical options. Avoid high-speed dry cutting, which can cause galling.
Titanium forms a stable, self-healing TiO₂ oxide layer that provides superior corrosion resistance to most grades of stainless steel in saltwater, chloride-rich, and mildly acidic environments. It is commonly specified for marine hardware, desalination equipment, and chemical reactors where 316L stainless would corrode over time. GR1 and GR2 offer the best corrosion performance; GR5 is slightly less resistant but still far exceeds most stainless alloys.
Yes. All three grades are weldable using TIG (GTAW) welding with 100% argon shielding gas and a trailing shield to protect the weld zone from oxidation until it cools below approximately 400 °C. GR1 and GR2 are the most weld-friendly. GR5 (TC4) requires more careful heat management and post-weld annealing for structural applications. Avoid MIG welding without proper shielding, as titanium will embrittle rapidly when exposed to oxygen or nitrogen at elevated temperatures.
These sheets are suitable for prototyping, R&D, and non-certified fabrication work. GR1 and GR2 are biocompatible per ISO 10993 guidelines and are widely used in medical device prototyping, dental fixtures, and laboratory tooling. GR5 (TC4) is the standard aerospace structural alloy per AMS 4911. For flight-certified or implant-grade applications, please verify material certifications (mill certs / MTRs) with your procurement team before ordering.
The base variant is 100 mm × 100 mm (approx. 3.94" × 3.94") with 1 piece. Additional size and multi-piece quantity options are listed in the Size & Amount variant selector above.
