Acid-resistant GR7 (Ti-Pd) titanium coils - for high-end chemical reactors

Our precision-rolled titanium coils are engineered for continuous processing adaptability, covering a diverse range of grades to serve high-end industries—including commercially pure (GR1, GR2, GR4), alloyed (GR5 Ti-6Al-4V, GR7 Ti-Pd, GR9 Ti-3Al-2.5V), and medical-grade (Ti-6Al-4V ELI). GR1/GR2 offer exceptional ductility and corrosion resistance, ideal for roll-forming into lightweight, corrosion-prone components; GR5 delivers a standout strength-to-weight ratio (tensile strength up to 860MPa) for structural parts requiring both rigidity and formability; GR7’s palladium addition enhances resistance to reducing acids, suited for aggressive chemical processing.

We provide flexible roll material-specific specifications: thickness ranges from 0.15mm (ultra-thin for precision stamping) to 6mm, width from 500mm to 2000mm, and maximum coil weight up to 5 tons, with custom slit widths available for automated production lines. All coils undergo specialized processing—precision cold rolling with tension control, continuous annealing in protective atmospheres, and optional continuous passivation—to ensure uniform thickness tolerance (±0.01mm for thin gauges) and consistent mechanical properties. Surface finishes include mill-finished, pickled, or polished, optimizing compatibility with downstream processes like welding, stamping, or coating.

Leveraging titanium’s inherent advantages (low density 4.51g/cm³, seawater/chlorine resistance, biocompatibility) plus roll material-specific benefits (efficient roll-to-roll manufacturing, minimal material waste), these coils excel in aerospace (aircraft skin rolls, engine ducting), medical (implantable device blanks via continuous stamping), chemical (Continuous molding pipe lining), marine (offshore structure cladding), and electronics (heat exchanger fins). Compliant with ASTM B265, ASME SB265, and ISO 5832, each batch undergoes rigorous testing—ultrasonic inspection, tensile/elongation analysis, and corrosion trials. We offer bulk supply, just-in-time delivery, and technical support for global clients needing high-performance, process-efficient titanium roll material.
