Q: What international standards do your Titanium Wires comply with?

A: Our Titanium Wires are manufactured in strict compliance with global mainstream standards, including ASTM B863 (the core standard for titanium and titanium alloy wire), AWS A5.16 (titanium welding wire standard), ASTM F67/ASTM F136 (medical-grade titanium standards), AMS 4951/4954 (aerospace standards), NACE MR0175/ISO 15156 (sour oil and gas service standard), and ISO 5832-3 (medical titanium alloy standard). We also support custom production according to DIN, JIS, and GB standards, ensuring 100% compatibility with your application and processing requirements.

Q: What is the difference between cold drawn and hot drawn Titanium Wire?

A: The core differences lie in processing method, dimensional range, surface quality, and application scenarios:

- Cold Drawn Titanium Wire : Processed at room temperature, diameter range 0.01mm-6.0mm, with ultra-precise dimensional tolerance, smooth surface (Ra ≤0.4μm), and excellent cold formability. It is ideal for medical implants, precision electronic components, jewelry, and fine weaving.

- Hot Drawn Titanium Wire : Processed at high temperature (850-950℃), diameter range 6.0mm-20.0mm, with higher strength, uniform structure, and a pickled matte surface. It is designed for structural fasteners, welding rods, and heavy-duty industrial applications that do not require ultra-high surface finish.

Q: Which titanium grade should I choose for my application?

A: The grade selection depends on your working environment, mechanical requirements, and application scenario:

- For general industrial, medical (non-load-bearing), and consumer applications: GR2 is the most cost-effective and widely used choice, with balanced strength and formability.

- For deep drawing, fine weaving, and soft tissue implants: GR1 is optimal, with the highest ductility and cold formability.

- For high-pressure, high-temperature, and high-load applications (aerospace, load-bearing medical implants): GR5 (Ti-6Al-4V) high-strength titanium alloy is recommended.

- For medical implants (orthopedic, dental):GR23 (Ti-6Al-4V ELI) medical grade is required, compliant with ASTM F136 and ISO 5832-3.

- For harsh corrosive environments (reducing acids, high-temperature high-chloride): GR7 is the best choice, with palladium addition to enhance corrosion resistance.

Our technical team can provide professional grade selection guidance based on your specific working conditions.

Q: Are your Titanium Wires weldable? What welding process do you recommend?

A: Yes, all our Titanium Wires have excellent weldability, as we use vacuum double-melted raw materials with ultra-low impurity content and uniform microstructure. The recommended welding process depends on the wire grade and application:

- For pure titanium wire (GR1, GR2, GR7): GTAW (TIG) Welding with high-purity argon shielding (purity ≥99.999%) on both the front and back of the weld, using matching grade titanium welding wire.

- For titanium alloy wire (GR5, GR9, GR23): GTAW or laser welding, with strict control of welding temperature and argon shielding to avoid oxidation. We recommend using matching grade welding wire (e.g., ERTi-5 for GR5 wire).

The weld joint strength can reach more than 90% of the base metal, without pores, cracks, or oxidation defects. We can provide detailed welding parameter guidelines and matching welding wire recommendations with your order.

Q: What is the difference between Titanium Wire and Stainless Steel Wire?

A: Our Titanium Wire has irreplaceable core advantages over stainless steel (304/316L) wire:

- Superior Corrosion Resistance: Titanium is immune to chloride ion corrosion, seawater corrosion, and most acid/alkali media, while stainless steel is prone to pitting and crevice corrosion in harsh environments. The service life of titanium wire is 5-10 times that of stainless steel wire in corrosive scenarios.

- Ultra-Lightweight: Titanium density is 4.51g/cm³, only 60% of stainless steel, reducing the weight of components and lowering installation costs.

- Excellent Biocompatibility: Titanium is non-toxic, hypoallergenic, and non-precipitating, making it suitable for medical and food applications, while stainless steel may precipitate heavy metal ions.

- High Temperature Stability: Titanium wire maintains stable mechanical properties at -253℃ to 550℃, while stainless steel loses strength and corrosion resistance at high temperatures above 300℃.

While the initial procurement cost of titanium wire is higher, its long service life and low maintenance costs result in a lower total lifecycle cost in corrosive and high-demand applications.

Q: What payment terms do you accept for international orders?

A: We accept standard international trade payment terms to ensure the safety of both parties:

- T/T (Telegraphic Transfer): 30% deposit in advance, 70% balance before shipment.

- Irrevocable L/C at sight for bulk orders over 50,000 USD.
