When your project demands a material that refuses to corrode, flex under load, or add unnecessary mass, standard steel and aluminum fall short. Engineers, makers, and fabricators working on aerospace components, medical fixtures, marine hardware, and high-performance DIY builds rely on TC4/GR5 titanium plate sheet for its unmatched strength-to-weight ratio and long-term dimensional stability.
Each TC4/GR5 titanium plate is cut from Grade 5 (Ti-6Al-4V) alloy — the most widely used titanium alloy, composed of titanium with approximately 6% aluminum and 4% vanadium. Available in two flat panel sizes (100×100mm / ~3.94×3.94 in and 200×200mm / ~7.87×7.87 in) and twelve thickness options ranging from 0.5mm (~0.020 in) to 6.0mm (~0.236 in), these sheets cover a broad spectrum of structural and decorative applications.
Typical use cases include custom bracket fabrication for lightweight aerospace frames, corrosion-resistant shim stock for marine and chemical environments, precision heat shields for motorsport and high-temperature DIY builds, and structural panels for RC aircraft, drone chassis, and robotics platforms — all applications where titanium plate for CNC machining or hand fabrication delivers results that other metals cannot match.

For shim stock, gaskets, or thin structural skins, 0.5–1.0mm is typically sufficient. For brackets, mounting plates, and moderate structural panels, 1.2–3.0mm is the most common range. For heavy-duty structural components, heat shields, or parts subject to significant mechanical load, 3.5–6.0mm provides the necessary rigidity. If you are unsure, select your target load and consult a materials engineer or refer to Ti-6Al-4V design data sheets.
Yes. TC4 is the Chinese designation and GR5 (Grade 5) is the ASTM designation for the same Ti-6Al-4V alloy. All three names refer to the same titanium alloy composition: approximately 90% titanium, 6% aluminum, and 4% vanadium. It is the most widely used titanium alloy in aerospace, medical, and industrial applications.
TC4/GR5 titanium forms a stable, self-repairing titanium dioxide (TiO₂) oxide layer on its surface that provides excellent resistance to seawater, dilute acids, and many industrial chemicals. It significantly outperforms stainless steel in chloride-rich marine environments and does not require additional coatings or plating for most outdoor or wet applications.
Titanium can be cut with carbide-tipped tooling, waterjet, or laser cutting equipment rated for titanium. Standard high-speed steel (HSS) tools wear quickly on titanium — carbide or coated carbide tooling with appropriate cutting speeds and coolant is strongly recommended. For thin sheets (0.5–1.5mm), aviation snips or a fine-tooth metal saw can also be used for straight cuts.
Yes. TC4/GR5 is TIG weldable using Grade 5 or Grade 2 titanium filler wire. Welding must be performed with adequate inert gas shielding (argon) on both the front and back of the weld to prevent oxidation and embrittlement. Proper shielding is critical — unshielded titanium welds will discolor and lose mechanical properties.
The 100×100mm (~3.94×3.94 in) panel is ideal for small brackets, test coupons, prototyping, and single-component fabrication. The 200×200mm (~7.87×7.87 in) panel provides more material for larger components, multiple smaller parts cut from a single sheet, or applications requiring a wider flat surface. Both sizes are available in the full range of thicknesses.
Absolutely. TC4/GR5 titanium plate is a popular choice for high-performance drone frames, RC aircraft motor mounts, and structural ribs where minimizing weight while maintaining rigidity is essential. The 0.5–1.5mm thickness range is most commonly used for these applications, offering a strong, lightweight panel that can be cut to custom shapes with a waterjet or laser cutter.
