Explore our first tier of engineered raw titanium and custom forged components
Machining heavy-section titanium blocks into structural components is one of the most demanding processes in modern CNC milling. Titanium and its alloys (such as the classic alpha-beta Ti-6Al-4V Grade 5 and corrosion-resistant alloy Grade 7 / Grade 12) possess unique properties. While their exceptional strength-to-weight ratio and corrosion resistance make them irreplaceable, their low thermal conductivity poses extreme manufacturing challenges.
Unlike steel, where the thermal load generated during cutting is largely evacuated through the chips, titanium conducts very little heat. The thermal stress remains concentrated directly at the cutting edge. This leads to high temperatures at the tool interface (often exceeding 800°C), accelerating chemical tool wear and chipping. To mitigate this, our advanced factory environment utilizes specialized carbide tooling, optimized chip evacuation dynamics, and high-pressure through-spindle coolant delivery (up to 70 bar) to preserve machining integrity and avoid thermal surface defects.
As an established high-tech industrial enterprise founded in 2001, ProX Metal leverages the massive, vertically integrated industrial framework of China's core metal refining clusters. Operating out of a fully equipped manufacturing facility, our production line encompasses every stage of the raw materials cycle, from high-grade titanium sponge refining to double-vacuum arc remelting (VAR), precise forging, and finished block machining.
Industrial buyers searching for a Titanium Block Machining Factory require more than simple machining capabilities; they seek structural security, metallurgical reliability, and global compliance. In the chemical process industry, machined blocks serve as core components in pressure vessels and heat exchangers. In deep-sea oil exploration, titanium blocks are machined into critical manifolds and valve housings because they resist sulfide stress cracking in sour gas fields.
In desalination and electrochemical plants, titanium materials function under highly corrosive conditions, handling seawater, wet chlorine gas, and severe sulfuric acid lines. To ensure maximum operational lifetime, our machined blocks conform to standard requirements such as ASTM B381 for titanium forgings, ASTM B265 for plate structures, and ASTM B348 for bar and billet configurations.
Operating across international borders demands comprehensive quality certifications and local engineering support. ProX Metal is ISO 9001:2015 certified and holds 14 national patents related to advanced titanium processing techniques. We understand the specific regulatory frameworks governing major industrial markets, offering material test reports (MTR) according to EN 10204 3.1, detailing exact chemical and mechanical profiles for ultimate product traceability.
Whether your operations are based in North America, Western Europe, East Asia, or Central America, we provide customized support:

We deliver premium raw titanium products and precision machined parts across four key global sectors
In the chemical industry, it is widely used against highly corrosive media such as chlor-alkali and sulphuric acid. It ensures the efficient and safe operation of chemical production, prevents material leakage and guarantees product quality.
Supplies provide the high-strength, corrosion-resistant materials titanium for exploration, production and refining oil.
Corrosion resistance in sea water and brackish applications make titanium the material of choice in marine applications.
Titanium can improve the efficiency and extend the life of desalination equipment due to its corrosion resistance, high strength, light weight and good thermal conductivity.
The consumption of precision-machined titanium blocks is rising as heavy industries transition toward longer infrastructure lifecycle expectations. As offshore energy wells shift into deeper waters with higher ambient pressures and temperatures, critical components such as subsea valves, flowlines, and processing headers cannot be fabricated from traditional stainless steels without risking stress corrosion cracking. This has driven structural engineers to write Grade 5 and Grade 2 titanium directly into standard design practices.
Simultaneously, green industrial initiatives have accelerated demand in the hydrogen production sector. Titanium plates and machined block collectors serve as crucial anodic structures in Proton Exchange Membrane (PEM) electrolyzers, where they are exposed to highly acidic oxygen evolution reactions. Because our factory integrates raw slab production and precision machining, we maintain complete trace metal control, avoiding cross-contamination from iron or nickel particulates that could degrade electrochemical performance.
Furthermore, the industry is witnessing a shift toward hybrid manufacturing—specifically combining near-net-shape casting or forging with final sub-millimeter precision CNC milling. By executing both the initial heavy hydraulic forging and the high-tolerance post-machining in one unified facility, ProX Metal reduces processing times by 35% compared to multi-vendor options. This is a critical parameter for EPC contractors working under tight liquidated damages clauses.
Expert answers on mechanical specifications, quality checks, and logistics
Grade 2 is commercially pure (CP) titanium with excellent ductility and corrosion resistance but lower tensile strength (approx. 345 MPa). Grade 5 (Ti-6Al-4V) is an alpha-beta alloy with significantly higher tensile strength (minimum 895 MPa) and is heat-treatable. Grade 5 is much harder and more abrasive, exhibiting higher tool wear and requiring slower cutting speeds and higher coolant pressures compared to the more ductile Grade 2.
Every forged titanium block undergoes mandatory Ultrasonic Testing (UT) in accordance with ASTM A388 or ASTM B381 standards. This non-destructive testing method ensures there are no internal voids, hydrogen flakes, inclusions, or density variations. Full UT validation reports are included in the standard compliance documentation package.
We utilize high-pressure, through-spindle coolant (up to 70 bar) directly targeted at the tool-workpiece interface. This is critical for preventing heat accumulation on the cutting edge and facilitating instant chip evacuation, which avoids the chip recutting that causes catastrophic tool failure.
Yes. We supply standard EN 10204 3.1 Material Test Certifications (MTC) detailing chemical composition (ICP-OES analysis) and mechanical properties (tensile strength, yield strength, elongation). We also support inspections by third-party bodies such as SGS, TÜV, and Lloyd's Register for marine or pressure equipment compliance.
Titanium's high elastic modulus leads to spring-back during machining, causing vibration and tool rubbing. Additionally, its chemical reactivity at high temperatures causes tool materials to diffuse into the chip. Our engineers resolve this by utilizing high-rigidity CNC structures, custom carbide tooling coated with TiAlN or PCD, and keeping a constant positive feed rate to prevent work hardening.
Standard sizes using our in-stock 10-ton inventory can be shipped within 7–10 days. Fully customized designs requiring specialized dies, custom structural forging, or multi-axis milling operations typically ship in 4–6 weeks, depending on final geometry and order volume.
Yes, our titanium Grade 5 and Grade 12 products conform to NACE MR0175 standards for sour service application limits. They are thoroughly qualified for subsea hydrogen sulfide environments, ensuring protection against corrosion fatigue and hydrogen embrittlement.
Using our state-of-the-art multi-axis CNC mills and precision grinders, we consistently hit tight dimensional tolerances down to ±0.005mm. Surface roughness can be finished to Ra 0.4 μm depending on design requirements.
Yes, we support our global distributors and EPC clients with initial prototype runs. We offer complete testing packages for single-unit sample runs so engineers can verify the alloy's performance under actual stress conditions before full-scale production begins.
All machined parts are individually cleaned, treated with corrosion prevention oil where necessary, wrapped in protective foam, and shipped in custom-reinforced wooden crates. This ensures that precision surfaces and threads arrive free of mechanical defects or environmental corrosion.
