Titanium is a metal, and metals in general conduct electricity due to having free electrons which can move from atom to atom easily.
Compared to many other metals like copper, aluminum, or even iron, Titanium is quite the poor conductor of heat and electricity. Compared to non-metals, it can conduct electricity quite well but expensive and hard to work with.
With a conductivity value of 2.38×10^6, Titanium is very close to grain-oriented electrical steel, which has a conductivity value of 2.17×10^6. Steel frames being used as the ground path in most cars, it conducts electricity fairly well.
But the copper’s conductivity value is 5.96×10^7, 25 times better than steel and Titanium. In other words, If we consider copper to be 100 percent when it comes to conducting electricity, Titanium is less than 4 percent. Another metal that has a closer poor conductor is stainless steel.
When exposed to air, Titanium forms a protective layer that saves it from corrosion. In that case, the metal ends up being more of an insulator rather than a conductor. In that case, you’ll have to scrape off the top layer first if you will get the conductivity you’re looking for.
So Titanium is not that good a conductor compared to others. Also, they are expensive and brittle, hard to machine and form, and don’t bend easily without breaking, so they make very poor wires.
However, marketing departments like to name products and services and other stuff Titanium – cars, headphones, and other products even though they have little or no Titanium.
Aerospace engineers love it because it’s super lightweight for its strength. Marine engineers love it because it’s corrosion-resistant to a high degree.
I suspect Titanium sounds exotic, sounds expensive, and sounds high-tech. More so these days than platinum and gold, the previous popular names for products.
