introduction
Titanium Grade 2 in CNC Machining
Titanium Grade 2 is a commercially pure titanium with excellent corrosion resistance, high strength-to-weight ratio, and biocompatibility.
This material has thermal conductivity, so the heat generated during machining stays concentrated at the cutting edge. Therefore, we use carbide or high-speed steel (HSS) tools with sharp cutting edges to minimize cutting forces and reduce heat buildup. It also tends to work harden, so we use high cutting speeds to help reduce tool wear and proper feeds to prevent excessive tool pressure. Machining small pockets in titanium can be expensive, needing specialized tools. Tools should not exceed 70% of the pocket diameter for effective cooling. Extra costs for small pockets must be considered in projects.
Titanium grade 2 allows various treatments, including anodizing, which can enhance strength by thickening the oxide layer and changing the metal's color. Additionally, it can be easily cold-formed and has good weldability. It is particularly used in chemical processes due to its high resistance to various chemical environments, including oxidizing media, alkaline media, organic acids, compounds, aqueous salt solutions, and hot gases. Grade 2 titanium maintains corrosion resistance in diverse conditions such as liquid metals, nitric acid, mildly reducing acids, and wet chlorine or bromine gas.

TECHNOLOGY OVERVIEW
Basic Knowledge of Titanium Grade 2
What is Titanium Grade 2?
Titanium Grade 2 is a commercially pure titanium alloy that belongs to the commercially pure or unalloyed titanium grades. It is composed of 99.2% pure titanium, with small amounts of oxygen (0.1% maximum) and iron (0.3% maximum).
This grade of titanium has excellent corrosion resistance, especially in environments that involve saltwater, chemical exposure, and oxidizing acids. While not as strong as some other titanium alloys, Grade 2 still offers a good balance of strength and ductility. It has a tensile strength comparable to some low to medium-strength steels.
