Pure Titanium
Pure titanium, composed of approximately 99.89% titanium with trace elements like iron, carbon, nitrogen, hydrogen, and oxygen, is lightweight and corrosion-resistant. It withstands strong acids and alkalis, earning titles like "biophilic metal" for safe human implantation and "space metal" for aerospace applications. Essentially, it refers to raw, unprocessed titanium.

Composite Titanium
Composite titanium describes a unique physical structure rather than chemical alteration. In cookware development, steel-aluminum cladding technology enhances heating speed, improves heat distribution, reduces smoke, and increases durability. This layered "sandwich structure" preserves pure titanium's chemical properties while adding functional steel-aluminum outer layers.

Titanium Alloy
Titanium alloys incorporate strengthening elements like aluminum, nickel, chromium, and copper to enhance strength, corrosion resistance, and high-temperature performance. Vital across medical, aerospace, marine, and sports industries, these engineered materials demonstrate exceptional durability through metallurgical fusion and reshaping.

Titanium Gold ("Ti Gold")
"Titanium gold" lacks standardized definition. While the public broadly uses it for all titanium materials, industry professionals specifically refer to titanium nitride (PVD) coated materials mimicking gold's appearance. This surface treatment creates a golden finish without altering base material properties.
