Find answers to the most common questions about titanium materials, ordering, and our services.

Grades & Material Selection

What is the difference between Grade 2 and Grade 5 titanium?
Grade 2 is a commercially pure (CP) titanium with excellent corrosion resistance and good formability, commonly used in chemical processing and marine applications. Grade 5 (Ti-6Al-4V) is an alpha-beta alloy offering roughly double the tensile strength of Grade 2, making it the go-to choice for aerospace, medical implants, and high-performance engineering.
What is Ti-6Al-4V and why is it so popular?
Ti-6Al-4V is the designation for Grade 5 titanium, containing 6% aluminum and 4% vanadium. It accounts for over 50% of all titanium usage worldwide due to its outstanding strength-to-weight ratio, corrosion resistance, and biocompatibility. It is widely specified in aerospace structural components, surgical implants, and marine hardware.
Which titanium grade is best for seawater applications?
Grade 2 is the most cost-effective choice for seawater service, offering excellent resistance to chloride-induced corrosion. For higher-strength marine applications, Grade 5 or Grade 9 (Ti-3Al-2.5V) are commonly specified. In extreme environments such as hot brine or offshore oil and gas, Grade 7 or Grade 12 with palladium or molybdenum additions may be required.
What does "ELI" mean in Grade 23 (Ti-6Al-4V ELI)?
ELI stands for "Extra Low Interstitials," meaning the oxygen, nitrogen, carbon, and iron contents are held to tighter limits than standard Grade 5. This results in superior fracture toughness, better ductility, and improved fatigue life. Grade 23 ELI is the primary titanium alloy used for orthopedic and dental implants due to its enhanced biocompatibility.
What is the difference between CP titanium and titanium alloys?
Commercially Pure (CP) titanium — Grades 1 through 4 — contains 99%+ titanium with varying oxygen levels that control strength. Titanium alloys add elements like aluminum, vanadium, or molybdenum to significantly increase strength and high-temperature performance. CP grades are chosen for corrosion resistance and formability, while alloys like Grade 5 are selected when higher mechanical properties are required.
How do I choose the right titanium grade for my project?
The selection depends on your application environment, required mechanical properties, and budget. For general corrosion resistance, CP Grade 2 is the most widely used. For high-strength structural parts, Grade 5 is the standard.

Specifications & Standards

What is ASTM B265?
ASTM B265 is the standard specification for titanium and titanium alloy strip, sheet, and plate. It covers all commercially pure grades (1–4) and common alloys including Ti-6Al-4V. Most of our titanium sheet and plate products are supplied to this specification with full mill certification.
What is the difference between ASTM B348 and AMS 4928?
ASTM B348 is the standard specification for titanium bars and billets used in general industrial applications. AMS 4928 is an aerospace material specification for Ti-6Al-4V bars, forgings, and rings with stricter requirements on chemistry, mechanical testing, and traceability. We supply to both specifications depending on your industry requirements.
What certifications does your titanium come with?
All our products ship with Mill Test Certificates (EN 10204 3.1) documenting chemical composition, mechanical properties, and heat treatment records. We can also provide third-party inspection reports, material certificates per ASTM/AMS/ASME standards, and compliance documentation for specific industry requirements.
What is a Mill Test Certificate (MTC)?
A Mill Test Certificate (also called Mill Cert or MTC) is a quality document issued by the producing mill that certifies the chemical analysis and mechanical test results of a specific heat or lot. Our MTCs conform to EN 10204 Type 3.1, meaning the results are verified by the manufacturer's quality department and are traceable to the original ingot.
Do you provide third-party inspection reports?
Yes, we can arrange third-party inspection through internationally recognized agencies such as SGS, Bureau Veritas, or TUV. This can include dimensional verification, chemical re-analysis, mechanical re-testing, and visual inspection. Third-party inspection is available upon request and the cost is typically borne by the buyer.

Pricing & Ordering

How much does titanium cost per kg?
Titanium pricing varies significantly depending on the grade, product form, dimensions, quantity, and current raw material market conditions. CP Grade 2 is generally the most economical, while aerospace-grade alloys command a premium. Request a quote with your specific requirements for accurate pricing.
What is your minimum order quantity?
Our minimum order quantity varies by product form. For standard titanium bars and plates, we can accommodate orders as low as 50 kg. For custom specifications, the MOQ may be higher depending on the mill's production schedule. We are flexible and work with customers to find solutions for both small prototype orders and large-volume procurement.
How long does it take to get a quote?
We typically respond to quote requests within 24 hours during business days. For standard products in stock, we can often provide pricing within a few hours. Complex custom orders or specifications requiring mill consultation may take 2–3 business days. Submit your inquiry and we will respond as quickly as possible.
Do you accept custom sizes and specifications?
Yes, custom manufacturing is one of our core strengths. We can produce titanium products to your exact dimensions, tolerances, and specifications. This includes custom sheet/plate cutting, bar turning, tube drawing, and forging to drawing. Share your drawings or specifications with us for a tailored quotation.
What payment terms do you offer?
We accept T/T (telegraphic transfer) as our standard payment method. For new customers, we typically require 30% deposit with the balance paid before shipment. Established customers may qualify for more flexible terms. We also accept L/C (Letter of Credit) for larger orders.

Machining & Processing

Is titanium difficult to machine?
Titanium can be machined successfully with proper tooling and techniques, but it does require more care than steel or aluminum. Key factors include using sharp carbide tools, maintaining low cutting speeds with high feed rates, ensuring adequate coolant flow, and avoiding dwell time. Our machining partners have extensive experience processing titanium and can handle complex geometries.
Can titanium be welded?
Yes, titanium is readily weldable using TIG (GTAW) and electron beam welding processes. The critical requirement is complete shielding from atmospheric contamination — the weld zone, heat-affected zone, and back side must be protected with inert gas (argon or helium) until cooled below approximately 500°F (260°C). We can supply titanium welding wire and offer technical guidance on welding procedures.
What surface finishes are available?
We offer a range of surface finishes including mill finish (as-rolled or as-forged), pickled and annealed, ground, polished, and blasted. For bars, we provide hot-rolled, cold-drawn, centerless ground, and polished finishes. Specific surface roughness requirements (Ra values) can be met upon request.
Do you offer cut-to-length services?
Yes, we provide cut-to-length services for titanium bars, plates, and sheets. Cutting methods include precision sawing, waterjet cutting, and plasma cutting depending on the material thickness and required tolerance. This helps reduce your material waste and machining time.
Can you do CNC machining on titanium parts?
Yes, we offer CNC machining services for titanium components through our network of experienced machining partners. Capabilities include CNC milling, turning, drilling, and multi-axis machining. We can work from your CAD drawings or samples to produce finished or semi-finished parts to your specifications.
