Frequently Compared Questions

What is the main difference between Ti-6Al-4V (Grade 5): The Workh and Aluminum 7075-T6: Aerospace-St?

Ti-6Al-4V (Grade 5): The Workhorse Titanium Alloy (ASTM B265/B348 / AMS 4911) provides 880 MPa (128 ksi) annealed yield strength at 4.43 g/cm³ density, while Aluminum 7075-T6: Aerospace-Strength Al-Zn-Mg-Cu Alloy — Aircraft Structures & High-Stress Parts (ASTM B209 / AMS 4045 / AMS-QQ-A-250/12) delivers 503 MPa (73 ksi) typical for plate ≤25 mm at 2.81 g/cm³. The choice depends on whether your application prioritizes maximum strength at elevated temperature (up to 350°C) or lower cost and weight for ambient-temperature applications.

Can Ti-6Al-4V (Grade 5): The Workh be substituted for Aluminum 7075-T6: Aerospace-St?

Direct substitution is generally not recommended as these materials belong to different categories (Titanium Alloy vs Aluminum Alloy) with fundamentally different properties. Consult a materials engineer for application-specific guidance.
