Why is titanium alloy so difficult to process？

Titanium taps (such as TC4) are more difficult to process than most alloy materials, but it is possible to choose the right tap. Titanium, which is both hard and lightweight, is a very attractive metal for use in aerospace, medical and other industries.

However, the material characteristics of titanium alloy pose a challenge for many processing plants, and many engineers are looking for suitable solutions for the material.

Titanium, for example, does not conduct heat very well. When working titanium, heat tends to accumulate on the surface and edges of the tool rather than dissipate through parts and machine structures. This is especially true when tapping because there is more contact between the inside surface of the hole and the tap than between the workpiece and the drill, end mill, or other tool. This retained heat causes the cutting edge to notch and shortens the tap life.

In addition, titanium's rather low modulus of elasticity makes it "elastic", so the workpiece tends to "bounce back" on the tap. This effect can cause thread wear and tear. It also increases the torque on the tap and shortens the service life of the tap (so many times it is not recommended to find some imported second-hand tap is also in this reason, the tap has gone through a strong torque, if the tap will be very big risk).

For best results when tapping titanium alloy, use a special brand tap, mount it in the tap shank, and select the appropriate parameters on a machine tool with good feed control.
