Commercially Pure Titanium & Titanium Alloys

Titanium & Titanium Alloys — Technical Sourcing

Grades, product forms, dimensions and documentation coordinated for industrial, marine, aerospace and medical requirements.

MNK-G.S.A supports the sourcing of commercially pure titanium and selected titanium alloys through European and international supply routes. We review the required grade, governing specification, product form, dimensions, condition, tests and inspection documents before quotation.

All Products & Materials

The Complete Specification Controls the Material

A grade name alone is not sufficient. Commercially pure Grades 1–4, Grade 5, Grade 23 ELI and Ti-6Al-7Nb have different chemistry, mechanical-property and application controls. Product form, heat-treatment condition, surface finish, dimensional tolerance and the governing industrial, aerospace or implant specification must be stated and verified.

Material Groups

CP Titanium Grades 1–4

Grade 1 / UNS R50250 / 3.7025, Grade 2 / UNS R50400 / 3.7035, Grade 3 / UNS R50550 / 3.7055 and Grade 4 / UNS R50700 / 3.7065. The four commercially pure grades combine corrosion resistance and weldability with increasing strength from Grade 1 to Grade 4.

Grade 5 / Ti-6Al-4V

UNS R56400 / 3.7164. A widely used alpha-beta titanium alloy selected where a higher strength-to-weight ratio, fatigue resistance and corrosion resistance are required. Industrial and aerospace requirements must be matched to the correct product specification and approved supply route.

Grade 23 / Ti-6Al-4V ELI

UNS R56401. The ELI version has more tightly controlled interstitial elements than standard Grade 5. Some European stock catalogues use material number 3.7165; that reference is accepted only after the certificate and governing specification have been checked. Grade 5 and Grade 23 are not treated as automatically interchangeable.

Ti-6Al-7Nb & Selected Grades

Ti-6Al-7Nb / UNS R56700 may be sourced against ISO 5832-11 or ASTM F1295 when specified. Additional requirements may cover Grades 7, 9, 12 and other corrosion-resistant or high-performance titanium grades, subject to exact grade, form and standard verification.

Common market names and European material numbers support inquiry matching. The ordered material is controlled by the agreed grade, product specification, condition and inspection documentation.

Published supplier examples

The dimensions below are examples from the ACNIS and Alleima catalogues, not a combined guarantee of MNK stock or supplier qualification. Different product programmes have different limits. Other sizes and grades can be reviewed against your specification.

Round Bar — Diameter & Length

Grade 1: Ø0.4–300 mm; length about 3000 mm in the industrial/aerospace catalogue. ACNIS.
Grade 2: Ø0.4–300 mm; length about 3000 mm in the industrial catalogue. ACNIS.
Grade 4: Ø1–100 mm; length 2000–3500 mm in the medical catalogue. ACNIS.
Grade 5: industrial bar Ø10–260 mm, about 3000 mm; aerospace bar Ø6–320 mm, about 2000–4000 mm. These are separate supplier programmes. ACNIS.
Grade 23 ELI: Ø1.2–110 mm; length 3000 mm. ACNIS.
Ti-6Al-7Nb: Ø1–100 mm; length about 3000 mm. ACNIS.

Selected small and medium diameters are available ground or polished to h6/h7-type tolerances. Exact tolerance, straightness, surface roughness and usable length are confirmed with the material specification.

Sheet & Plate — Thickness & Format

Grade 1: thickness 0.4–60 mm, width 1000–2000 mm, length 1000–6000 mm. ACNIS.
Grade 2: thickness 0.4–60 mm, width 1000–2000 mm, length 1000–6000 mm. ACNIS.
Grade 4: thickness 0.5–10 mm, width 1000–1250 mm, length 2000–2500 mm in the medical catalogue. ACNIS.
Grade 5: industrial plate 5–60 mm; aerospace sheet/plate 0.4–110 mm. Both programmes list widths 1000–2000 mm and lengths 1000–6000 mm. ACNIS.
Grade 23 ELI: thickness 0.8–120 mm, width 1000–1500 mm, length 2000–3000 mm. ACNIS.

Full-sheet, full-plate and cut-piece supply are available depending on grade and thickness. Waterjet, sawn or other approved cutting routes may be coordinated when technically appropriate.

Tube & Pipe — OD, Wall & Length

Precision titanium tubing: Alleima lists OD 9.53–38.1 mm, wall 0.7–5 mm and straight length ≤16500 mm; the grade and feasible OD/wall combination must be confirmed. Alleima.
Grade 2 seamless tube: the Alleima table lists OD 9.5–24.4 mm and length ≤17000 mm. Its minimum-wall entry conflicts with the accompanying graph. Wall thickness and the exact OD/wall combination therefore require written supplier confirmation; no minimum wall is guaranteed here. Alleima. Review Titanium Grade 2 heat-exchanger and condenser tubes →
Selected Grade 1 and Grade 5 tubes: ACNIS lists Grade 1 OD 3–50.8 mm and wall 0.3–5 mm ACNIS Grade 1; Grade 5 OD 3–50.8 mm and wall 0.3–5 mm ACNIS Grade 5. Confirm the grade, product route and feasible size combination.
Process pipe: larger seamless or welded Grade 2 and corrosion-resistant titanium pipe is sourced against OD or NPS/DN, schedule or wall thickness, end preparation and required fixed or random length.

Wire, Flats, Forgings & Components

Wire: the ACNIS Grade 1 aerospace catalogue lists Ø0.32–10 mm. Other grades and welding wire are confirmed by specification. ACNIS.
Flat bar: the ACNIS Grade 1 catalogue lists thickness ≥3 mm, width ≥10 mm and length ≤6000 mm. ACNIS.
Additional forms: discs, rings, hollow bar, billet, fasteners, flanges, fittings, forgings, cut blanks and machined parts against drawing.
Processing: sawing, waterjet cutting, grinding, polishing, trepanning, machining and controlled fabrication may be coordinated through qualified routes.

These published examples do not imply that every diameter, thickness and length can be combined, or that every grade is available in every size. Current availability, minimum quantities, tolerances, finish, condition, cutting allowance, traceability and delivery time are confirmed for each inquiry.

Application Context

Chemical & Process Equipment

Heat exchangers, vessels, tubing, piping, valves and fabricated components for corrosive process environments.

Marine & Desalination

Grade- and design-specific titanium may be considered for seawater systems, desalination, offshore equipment and marine hardware.

Aerospace & High Performance

Grade 5 and selected alloys are used where strength-to-weight ratio and fatigue performance are important, subject to the approved aerospace specification and supplier route.

Medical & Precision

Precision bars and implant-material routes are available only against the exact medical standard, approved condition, traceability, cleanliness and inspection-document requirements.

Application examples are not automatic material recommendations. Suitability depends on the environment, temperature, pressure, loading, fabrication route, design code and qualification requirements.

Standards & Verification

Material, product-form, application and inspection-document standards serve different purposes. The correct combination and current edition are established for the requested product before order placement.

Industrial Product Standards

ASTM B265-25 — strip, sheet and plate.
ASTM B348/B348M-25 — bars and billets.
ASTM B338-17(2026) — condenser and heat-exchanger tubes.
ASTM B381-26 — forgings.
ASTM B861-24 — seamless pipe.
ASTM B862-23 — welded pipe.

EN scope checked on 19 October 2026 against the public DIN and BSI records linked above. These limits describe the scope of the standards, not available stock or manufacturing capacity; conformity requires the applicable full standard and product documentation.

Implant-Material Standards

ISO 5832-2:2025 / ASTM F67-24 — unalloyed titanium for surgical-implant manufacture.
EN ISO 5832-3:2021 — wrought Ti-6Al-4V for surgical-implant manufacture.

Medical Supply Requires More Than a Grade Name

A certificate showing “Grade 5” does not establish compliance with Grade 23 ELI or an implant standard. Medical inquiries require the exact standard and edition, approved melt and manufacturing route, condition, chemistry and mechanical properties, microstructure where applicable, surface and cleanliness requirements, full heat traceability and the agreed inspection package.
