When your project demands a material that won't add unnecessary bulk but can't afford to compromise on strength or corrosion resistance, standard steel or aluminum often falls short. Engineers, makers, and hobbyists working on weight-critical builds — from custom brackets and aerospace components to knife blanks and RC frames — need a reliable source of accurately sized titanium stock they can trust right out of the package.
This TC4 (Grade 5, Ti-6Al-4V) titanium sheet plate measures 3mm × 100mm × 240mm (approximately 0.118" × 3.94" × 9.45"). It is machined from solid Grade 5 titanium alloy, the most widely used titanium grade, combining high tensile strength with low density. The plate surface is mill-finished, offering a clean, consistent appearance suitable for further machining, anodizing, or direct use.
Typical applications include custom titanium knife scales and blade stock for bladesmithing, lightweight structural brackets for drone and RC vehicle builds, heat-resistant shielding panels for automotive and motorsport fabrication, and precision test coupons for titanium welding and machining practice.

TC4 is the Chinese designation for Grade 5 titanium alloy, also known internationally as Ti-6Al-4V. It contains approximately 6% aluminum and 4% vanadium, which significantly increases its strength compared to commercially pure (CP) titanium grades 1–4. It is the most widely used titanium alloy in aerospace, medical, and engineering applications due to its balanced combination of strength, low weight, and corrosion resistance.
Titanium can be cut with carbide-tipped saw blades, angle grinders with appropriate discs, waterjet cutters, laser cutters, and EDM wire. Standard high-speed steel (HSS) tools will wear quickly. Use slow cutting speeds, high feed rates, and adequate coolant to prevent work hardening. Avoid letting the material overheat during cutting.
Yes. TC4 titanium is a popular choice for knife scales, liners, and bolsters due to its corrosion resistance, light weight, and attractive appearance when anodized. Note that TC4 is not typically used for blade edges as it does not hold a sharp edge as well as tool steels — it is best suited for handle components and structural knife parts.
TC4 titanium has excellent corrosion resistance. It naturally forms a stable, self-healing titanium dioxide (TiO₂) oxide layer on its surface that protects against saltwater, most acids, and atmospheric corrosion. It is widely used in marine hardware and coastal structures without additional coatings, making it a reliable choice for outdoor and wet-environment applications.
Yes, TC4 titanium can be TIG (GTAW) welded. It requires strict shielding with pure argon gas on both the front and back of the weld to prevent oxidation and embrittlement. Welding should be performed in a clean environment. MIG welding is possible but less common for titanium. Avoid welding near contaminants such as oils, grease, or other metals.
This plate comes with a standard mill finish — a clean, slightly matte metallic surface as produced during rolling. It can be anodized using a simple electrolytic process to produce a range of colors (gold, blue, purple, green) without dyes or coatings. Anodizing also adds a thin additional oxide layer for slightly improved surface hardness.
This listing is for a single plate measuring 3mm × 100mm × 240mm. Consider your finished part dimensions and add material allowance for cutting, machining, and finishing.
