Commercial Pure Titanium: TA1 & TA2
TA1 features maximum elongation and ultra-low interstitials, presenting extraordinary resistance to pitting in seawater and oxidants. TA2 is the industry's workhorse grade, offering the best equilibrium of weldability, cold deformation, and moderate mechanical load resistance.
Aerospace Titanium Alloy: TC4 (Grade 5)
TC4 contains 6% Aluminum for α-phase strengthening and 4% Vanadium for β-phase stabilization. It provides twice the load capacity of TA2 with a 40% weight deduction compared to 316L or 4140 steel, maintaining extreme fatigue limit under cyclical dynamic stress.
Palladium & Molybdenum Modifications
Grades like TA9 (Gr.7 Ti-0.2Pd) and TA10 (Gr.12 Ti-0.3Mo-0.8Ni) deliver enhanced anti-crevice and anti-reducing acid performance, bridging pure titanium workability with specialized resistance.

Direct Factory Price Advantage
- Zero middleman markups directly from our Shandong production base.
- Annual output capacity reaching 250,000 tons across alloys.
- Free material sampling available for qualified engineering trials.
- Standard stock ready for dispatch within 3–5 working days.
Buyer Caution: Identifying Market Traps & Verifying Quality
Protect your aerospace and critical systems from scrap blending, negative tolerance, and fake MTCs.
1. Material Grade Substitution
Substandard suppliers frequently supply TA2 labeled as TC4, pocketing the steep price difference. How to detect: Conduct on-site handheld XRF alloy analysis. TC4 must show distinct peaks for 5.5-6.75% Al and 3.5-4.5% V, while pure titanium exhibits over 99.2% pure Ti.
2. Negative Thickness Tolerances
Cutting plate thickness below standard EN 10258 / ASTM limits (e.g., supplying 4.6mm instead of 5.0mm) compromises mechanical safety. How to detect: Implement multi-point micrometer gauging across edge and center zones, coupled with ultrasonic thickness testers.
3. Subsurface Cracks & Porosity
Poorly annealed or recycled sponge titanium creates brittle alpha-case layers and internal voids. How to detect: Demand 100% Ultrasonic Testing (UT) per AMS 2631 standards and dye penetrant testing before container loading.
Global Market Dynamics & Regional Demand Trends
Strategic timing for aerospace alloy stockpiling across European, American, and Asian markets.
Europe & North America
Strict demand for AMS 4911, AMS 4928, and ISO 5832 specifications. Heavy demand focuses on TC4 ELI and Grade 5 for commercial aircraft fleet expansion and defense structures. Long-term forward contracts are recommended to protect against sponge titanium raw market surges.
Southeast Asia & Middle East
Rapid growth in seawater desalination facilities, petrochemical refining revamps, and marine platform construction, prioritizing high volumes of TA1/TA2 coils, welded titanium tubes (ASTM B338), and clad plates. Spot inventory purchasing is optimal.
Strategic Stockpiling Advice
Due to energy costs influencing chlorination and Kroll reduction processes, titanium sponge prices fluctuate cyclically. We recommend locking rolling quotas quarterly with our factory to stabilize project procurement budgets.
Frequently Asked Questions (FAQ)
Everything you need to know about our certifications, processing, packing, and orders.
What certificates and test reports are provided with the shipment?
Every shipment from Shandong Baimaoxing Iron and Steel includes an original Mill Test Certificate (MTC) conforming to EN 10204 3.1. This details the exact heat number, chemical composition, tensile/yield values, elongation, flattening tests, and non-destructive ultrasonic testing (UT). Third-party inspection reports from SGS, TUV, or BV are available upon request.
Can you provide plasma cutting, waterjet cutting, and custom profiling?
Yes. Our processing plant features high-precision CNC waterjet cutting (preventing heat-affected zones), plasma plate cutting, laser profile cutting, shearing, edge beveling, centerless grinding, and deep-hole turning to match custom customer drawings precisely.
How is titanium packaged to prevent damage during sea and air export?
We use export-standard seaworthy packaging. Plates and coils are layered with moisture-proof paper, wrapped in protective plastic film, steel-strapped, and placed inside fumigation-free wooden crates or reinforced plywood boxes. Bars and pipes are securely bundled with end caps to prevent edge abrasion.
What is your Minimum Order Quantity (MOQ) and sample policy?
For standard warehouse inventory, the MOQ is as low as 1 piece / 100 kg (tubing/bars standard MOQ is 1 ton). We gladly provide free small material samples (sheets, bar billets) for composition verification and laboratory testing before bulk dispatch.
What is the lead time for standard stock vs customized orders?
In-stock materials ship within 3 to 5 business days after payment confirmation. Custom decoiling, custom sizing, special alloy meltings, or heavy machining typically require 10 to 20 business days depending on specific production complexity.
