Titanium Grade 5 is the strongest titanium alloy with good corrosion resistance and the ability to be welded. Titanium may be selected over other materials such as steel due to its ability to withstand high and subzero temperatures. Common use cases include aerospace fasteners, turbine blades, engine components, sports equipment and marine applications.

Titanium is very similar to most grades of stainless steel in terms of overall appearance. Titanium can be media blasted or tumbled to achieve a multitude of surface finishes. Additionally, a light, protective, coating may be applied using passivation.

What is the cutting speed of titanium?
When CNC machining titanium, low cutting speeds are recommended. Tool tip temperatures can be easily increased by higher cutting speeds, which can compromise tools. Other related factors include sharp tools regularly replaced at the first sign of wear, feed rates high enough to prevent work hardening and the generous use of coolant.
Can you machine titanium with HSS tools?
High speed steel (HSS) drills are excellent for Titanium so long as it is sharp, but carbide tipped drills still provide the best results and deep hole drilling. Because titanium is not a great conductor of heat, much of the heat goes into cutting tools, highlighting the need for sharp and well-maintained tools.
Why is CNC machining titanium difficult?
Some of the factors that can make CNC machining titanium difficult are:
What is the best grade of titanium?
Grade 4 titanium is generally considered the strongest pure titanium, although the least moldable. It also has excellent corrosion resistance and outstanding ductility. Titanium is also lighter weight than some steels, such as stainless, due to its low density.
