Titanium alloy

Titanium alloy is a lightweight, high-strength alloy based on titanium with aluminum, vanadium, nickel and other elements added. Its application can be traced back to the aviation industry in the 1950s, and now it has become the core material for fighter jets, spacecraft and high-end medical devices.

Three core advantages of titanium alloy
1. Extremely light but high strength

The density is only 57% of steel (about 4.5g/cm³), but the tensile strength can reach more than 900MPa (close to some tool steels).

This makes titanium alloy knives lighter than steel knives while still maintaining sufficient structural strength.

2. Super corrosion resistance

A dense titanium oxide (TiO₂) protective film naturally forms on the surface of titanium, making it almost unaffected by water, salt and acid.

Even if it is immersed in seawater for many years, it will not rust, far exceeding the corrosion resistance of stainless steel.

3. Biocompatibility

Titanium is non-toxic and harmless to the human body and does not cause allergic reactions, so it is often used in medical implants (such as artificial joints).

This feature also makes it an ideal choice for food-grade knives.
