Electrical Resistivity of Common Titanium Alloys

The electrical resistivity of titanium alloys is generally low, making them relatively good conductors of electricity. Titanium itself is a metal known for its excellent corrosion resistance, high strength-to-weight ratio, and biocompatibility. When alloyed with other elements, such as aluminum or vanadium, titanium alloys can exhibit favorable electrical conductivity properties.

The following table provides a list of electrical resistivity values for common titanium alloys at standard room temperature (approximately 20°C or 68°F) and 1 atmospheric (atm) pressure. (1 atm = 101,325 Pa)
