TA1 titanium alloy tube is a commercial pure titanium tube corresponding to ASTM Grade 1, featuring the best plasticity and toughness in the commercial pure titanium series. With excellent corrosion resistance, good processability, formability and biocompatibility, it is widely used in chemical industry, marine engineering, medical care, energy and other fields, serving as an ideal structural and transportation material for medium-low temperature and weak corrosion environments.

Basic Information

• Material Grade: Chinese Standard TA1; ASTM Grade 1; ISO 5832-1; Russian Standard BT1-0.
• Material Type: α-type titanium alloy (single-phase), no alloying elements, Ti content ≥99.5%, low-strength with outstanding plasticity and corrosion resistance.
• Product Form: Seamless tube (mainstream) and welded tube; round, square, rectangular and customizable special-shaped tubes.
• Standards: GB/T 3624.1, GB/T 3625 (China); ASTM B337, B338, B861, B862 (USA); ISO 5832-1, ISO 12772 (International).

Key Parameters

Chemical Composition (wt. %): Ti (balance), Fe≤0.15, C≤0.08, N≤0.03, H≤0.015, O≤0.18. Medical-grade tubes require O≤0.12% and Fe≤0.10% (ASTM F67).

Mechanical Properties (Annealed): Tensile strength ≥240MPa, yield strength ≥170MPa, elongation ≥30%, hardness ≤100HB, ensuring good formability.

Specifications: Outer diameter: 3-219mm (seamless), 10-1000mm (welded); wall thickness: 0.5-20mm (seamless), 0.3-15mm (welded); length: 1-12m (customizable).

Surface Conditions: Pickling (conventional), bright annealing (high finish), polished (mirror/matte), sandblasted (customizable particle size).

Production Process

Seamless tube: Titanium sponge → vacuum smelting → hot extrusion → pickling → multi-pass cold rolling/cold drawing → annealing → finishing → NDT → packaging. Welded tube: Titanium strip/plate → roll forming → TIG welding → weld annealing → sizing → NDT → packaging. Strict temperature and purity control ensures product quality.

Core Features

• Excellent corrosion resistance in seawater, acids, alkalis and chlorides, far superior to stainless steel.
• Outstanding plasticity and toughness, suitable for bending, stamping and welding, no low-temperature brittleness.
• Lightweight (4.51g/cm³) and good thermal conductivity, ideal for heat transfer equipment.
• Non-toxic, non-magnetic, good biocompatibility, suitable for medical devices.
• Eco-friendly (100% recyclable) and long service life (20-50 years).

Applications

Chemical/petrochemical (corrosive medium pipelines); marine engineering (seawater cooling, desalination); energy (heat exchangers, condensers); medical (artificial blood vessels, instruments); food/pharmaceutical (hygienic pipelines); sports and precision instruments.

Quality Assurance & Notes

Each batch undergoes strict inspection: chemical composition, mechanical properties, dimensional accuracy, surface quality, NDT and packaging. Storage: dry, ventilated, away from corrosives. Usage: avoid high temperature (>350℃), use argon protection for welding. Transportation: anti-collision packaging.

Summary: TA1 titanium alloy tube is a cost-effective choice for medium-low temperature and weak corrosion scenarios, with customizable specifications and reliable quality, widely trusted in various industries.
