Titanium Grade 5, also known as Ti-6Al-4V or TC4, is the most widely used titanium alloy. Alloyed with around 6% aluminium and 4% vanadium, it pairs a two-phase alpha-beta structure with an exceptional strength-to-weight ratio, outstanding corrosion resistance and excellent biocompatibility.
Its strength holds from cryogenic conditions up to roughly 427°C, which is why Grade 5 is specified for jet engine parts, airframe components, pressure vessels, high-performance fasteners and frames. It can be supplied annealed or solution treated and aged, depending on the strength and toughness required.
We CNC mill and turn Grade 5 titanium with rigid set-ups, sharp tooling and plenty of coolant, as its low thermal conductivity concentrates heat at the cutting edge. It is non-magnetic and suits medical, marine and lightweight structural parts. Get an instant quote for Grade 5 titanium parts with UK delivery.

Values shown are typical supplier figures for Titanium Grade 5 (TC4) and may vary with stock condition. Please confirm critical properties before production.
Titanium Grade 5 (Ti-6Al-4V) is more demanding to machine than aluminium or steel. It conducts heat poorly, so it is cut at lower speeds with careful cooling, which increases machining time.
Grade 5 is used for precise aerospace and medical parts; thin walls need careful planning. Achievable tolerances depend on part size, geometry and features, so mark any critical tolerances on a 2D drawing with your upload and they will be reviewed and confirmed in your quote.
Grade 5 can be supplied as machined or bead blasted, and it is available annealed or solution treated and aged. Its natural corrosion resistance means a coating is not usually needed.
Typical uses include aerospace components, marine and chemical equipment, medical and electronic parts, and fasteners and heat exchangers. It has excellent biocompatibility and is non-magnetic.
Titanium Grade 5 is stronger, more corrosion resistant and works at higher temperatures, but it costs more to buy and machine. Aluminium 7075 is a lighter, more economical choice when its strength is sufficient.
The typical lead time shown for titanium Grade 5 is 10 business days from an approved order. Quantity, finishing and any heat treatment can affect this, and your quote confirms the date before you order.
