Titanium alloys guide
Evaluate Ti-6Al-4V and similar titanium alloys by weight, corrosion resistance, cost, and machinability.
This guide is prepared for quick engineering review. Critical design decisions still require the relevant standard, supplier data, and engineering approval.
Problem / Objective
Titanium offers high specific strength and corrosion resistance, but cost, supply, and machining difficulty limit the decision.
Assumptions
- A high-value or weight-sensitive application is being evaluated.
- Supplier data sheets and certificates will be used.
- Machining and finishing cost are included in the decision table.
Step by step method
- Calculate the project value of weight reduction.
- Compare Ti-6Al-4V and commercially pure titanium.
- Check modulus and contact wear behavior.
- Record CNC parameters and tool cost.
- Require traceable certification for critical parts.
Common mistakes
- Machining titanium like steel.
- Forgetting deflection impact from lower modulus.
- Ignoring galvanic corrosion pairs.

Quick FAQ
Question: Why is titanium expensive?
Raw material, machining, and supply chain costs are higher than common steels and aluminum.
Question: Is titanium always stronger than aluminum?
It can have high strength-to-weight ratio, but alloy and heat treatment condition must be compared.
Question: What matters when machining titanium?
Heat buildup, tool wear, and suitable cutting fluid are critical.
