GR12 Titanium Foil Vs. Other Grades

In chemical processing, marine engineering, and other environments containing chlorine, acids, or alkalis where crevice corrosion is prone to occur, material stability and corrosion resistance directly determine equipment reliability. #GR12_titanium_foil (Ti-0.3Mo-0.8Ni), representing near-α corrosion-resistant titanium alloys (α+β corrosion-resistant titanium foils), leverages synergistic alloying effects of molybdenum and nickel. Compared to GR2 pure titanium foil and GR7 palladium-containing titanium foil in harsh corrosion environments while offering superior cost advantages, making it a key material for upgrading chemical processing equipment.

Outstanding Crevice Corrosion Resistance: Containing 0.3% Mo + 0.8% Ni, it exhibits zero crevice corrosion risk in 5% Cl⁻ environments at 100°C-far surpassing GR2 pure titanium foil and resolving its inherent susceptibility to crevice corrosion.

Balanced Strength and Formability: Tensile strength reaches 520 MPa-50% higher than GR2-with excellent elongation enabling cold rolling to ultra-thin specifications. Formability surpasses strength-focused GR5 titanium foil.

Superior cost-effectiveness: Corrosion resistance approaches that of GR7 palladium-containing titanium foil, yet eliminates the need for the precious metal palladium, reducing material costs by over 25%. This makes it suitable for large-scale industrial applications.

GR12 (TA10/Gr.12):
Corrosion resistance Approach TA9 (Excellent crevice corrosion resistance)
Core elements 0.3%Mo+0.8%Ni
Cost-effectiveness Lower than TA9, high value-for-money
Typical applications Chemical heat exchangers, offshore pipelines

GR7 (TA9/Gr.7):
Corrosion resistance Extremely strong (palladium-modified passivation layer)
Core elements 0.12%-0.25% Pd
Cost-Effectiveness Higher (due to palladium cost)
Typical Applications Hydrogen fuel cells, high-end medical equipment

GR2 (TA2/Industrial Pure Titanium):
Corrosion Resistance Average (prone to pitting)
Core elements No additives
Cost-Effectiveness Lowest
Typical Applications General industrial structural components
