Material Overview
Grade 1 Commercially Pure Titanium (CP-Ti)
Grade 1 is the highest purity grade of commercially pure titanium, offering the best formability, excellent corrosion resistance and minimal impurity content among all industrial titanium grades. With no alloying elements added, this material maintains the intrinsic chemical and physical properties of titanium, making it the preferred choice for research scenarios requiring high material purity and no elemental interference.
RapidKeen's ultra-thin Grade 1 titanium foils are produced through multi-pass precision cold rolling followed by vacuum annealing treatment, ensuring uniform thickness even at 1μm level, consistent grain structure, stress-free state and ultra-clean surface. Each batch undergoes strict in-process purity verification, thickness testing and surface inspection to meet the stringent requirements of academic research and analytical laboratories.
Extreme Thinness for Advanced Research: Our foil production supports minimum thickness down to 0.001mm (1μm), with precise thickness uniformity control, ideal for micro-nano fabrication, flexible electronics, thin-film interference experiments and high-sensitivity sensor development.
