Titanium Grade 1 vs Titanium Grade 2 (CP): 73% composition overlap. Some similarities but notable differences in alloying elements.
Titanium Grade 1 vs Titanium Grade 2 (CP)
Side-by-side chemical composition and mechanical property comparison.
Overview
Titanium Grade 1
3.7025
The softest and most ductile commercially pure titanium grade. Lowest O content (0.18% max) for maximum formability. Used for plate heat exchangers, chemical plant vessels, explosive cladding, deep-drawn parts, and anodizing applications. Lower strength than Grade 2 but superior formability.
Titanium Grade 2 (CP)
3.7035
The workhorse commercially pure titanium grade. Best balance of strength, ductility, and corrosion resistance among CP grades. Excellent resistance to seawater, chlorides, and oxidizing acids. Used for heat exchangers, chemical processing, marine hardware, desalination, and medical implants.
