Overview
Ti-6Al-4V (Grade 5) is the most widely used titanium alloy. With steel-like strength at about 56% of the density, it has the highest strength-to-weight ratio of the metals we machine.
It is corrosion resistant, non-magnetic and biocompatible, which is why it dominates aerospace and implant applications.

Machining Notes
Low thermal conductivity concentrates heat at the cutting edge, so speeds are low and tool wear is high — expect a much higher machining cost than aluminum.
