When your project demands a material that refuses to compromise between weight and structural integrity, standard steel or aluminum simply fall short. Engineers, machinists, and advanced DIY makers working on aerospace components, marine hardware, medical fixtures, or high-performance custom builds need a TC4 titanium alloy plate that delivers consistent mechanical properties in every batch.
This TC4 titanium alloy plate is machined from Grade 5 Ti-6Al-4V billet — the most widely used titanium alloy, combining 6% aluminum and 4% vanadium for an exceptional strength-to-weight ratio. Each plate measures 40mm × 100mm × 180mm (approximately 1.57" × 3.94" × 7.09"), with a mill-finish surface ready for further machining, anodizing, or direct use. Density is approximately 4.43 g/cm³, giving this piece an estimated weight of around 3.19 kg.
Typical use cases include CNC-machined aerospace brackets and structural inserts, marine and offshore hardware requiring saltwater corrosion resistance, custom knife blanks and blade stock for titanium EDC projects, and precision jig plates or fixture blocks in metalworking shops.
Ti-6Al-4V (Grade 5) delivers tensile strength typically in the 900–1,000 MPa range at roughly 60% the weight of equivalent steel, reducing overall assembly mass without sacrificing load-bearing capacity.
TC4 titanium forms a stable, self-healing oxide layer that resists saltwater, acids, and chlorine environments — making it a reliable choice for marine, chemical, and outdoor applications.
Retains mechanical properties up to approximately 300–400°C (572–752°F), suitable for exhaust components, heat shields, and other thermally demanding environments.
TC4 is widely accepted in medical and dental applications due to its non-toxic, non-allergenic properties — ideal for custom implant prototypes, surgical tool fixtures, and lab equipment.
Supplied with a consistent mill finish, this plate is ready for immediate CNC milling, drilling, or grinding. The flat, parallel faces reduce setup time and fixturing effort in precision machining workflows.
Each plate is cut to 40mm × 100mm × 180mm with dimensional tolerances typically within ±0.5mm, providing a reliable starting stock for tight-tolerance machined parts and custom fabrication projects.

This plate measures 40mm × 100mm × 180mm (approximately 1.57" × 3.94" × 7.09"). It is a versatile stock size suitable for CNC-machined brackets, custom knife blanks, fixture plates, aerospace inserts, and marine hardware components.
Yes. TC4 is the Chinese standard designation for Ti-6Al-4V, which is internationally known as Grade 5 titanium. It is the most commonly used titanium alloy, accounting for roughly 50% of all titanium usage worldwide, and is valued for its balance of strength, weight, and corrosion resistance.
TC4 / Ti-6Al-4V typically achieves tensile strength in the 900–1,000 MPa range, which is comparable to many alloy steels. However, titanium is approximately 45% lighter than steel, giving it a significantly superior strength-to-weight ratio — making it ideal for weight-critical structural applications.
TC4 titanium is highly resistant to corrosion in saltwater, chlorinated water, and most acidic environments. It forms a passive oxide layer that is self-healing when scratched, making it an excellent choice for marine hardware, offshore equipment, and outdoor fixtures that would cause rapid corrosion in steel or aluminum.
Yes, TC4 titanium is machinable with standard CNC milling, turning, and drilling equipment. It is recommended to use sharp carbide tooling, lower cutting speeds (typically 30–60 m/min for milling), generous coolant flow, and avoid work-hardening by maintaining consistent chip load. EDM (wire and sinker) is also compatible.
TC4 / Ti-6Al-4V is a popular choice for EDC (everyday carry) knife handles, frame locks, and custom tool bodies due to its light weight, corrosion resistance, and ability to be anodized in a wide range of colors. Note that TC4 is not typically used for cutting edges — blade steel is preferred for that purpose — but it excels as handle and structural material.
Yes. TC4 titanium responds well to Type II and Type III anodizing, producing vivid interference colors (gold, blue, purple, green) without dyes. It can also be passivated, PVD coated, bead blasted, or polished. The mill-finish surface supplied is an ideal starting point for any of these finishing processes.
