Titanium Alloys: Ti-6Al-4V, Ti-ELI & Commercially Pure Solutions

ForceBeyond is an AS9100 and ISO 13485-aligned manufacturing provider of high-integrity titanium components. Renowned for their outstanding strength-to-weight ratio, low density (40% lighter than steel), superior corrosion resistance, and total biocompatibility, titanium alloys are critical across the aerospace, defense, medical implant, and deepwater marine sectors.

From vacuum investment casting and heavy closed-die forging to micro-precision Swiss CNC turning, ForceBeyond manufactures Ti-6Al-4V Grade 5, Ti-6Al-4V ELI, and Commercially Pure (CP) titanium parts built for extreme performance.

Titanium Technical Capabilities & Mechanical Profiles

Titanium Grade Standard Specifications Tensile Strength (Min) Primary Material Performance & Uses
Ti-6Al-4V (Grade 5) UNS R56400
AMS 4928 / ASTM B367
895 MPa (130 ksi) The most widely used alpha-beta titanium alloy. Combines high mechanical strength, light weight, and high corrosion resistance. Used for Aerospace Brackets and airframe fittings.
Ti-6Al-4V ELI (Grade 23) UNS R56401
ASTM F136 / AMS 4930
860 MPa (125 ksi) "Extra Low Interstitials" version with reduced oxygen/iron content for maximum fracture toughness and biocompatibility. Essential for Medical Bone Screws & Joint Implants.
Commercially Pure (Grade 2) UNS R50400
ASTM B348 / ASTM B265
345 MPa (50 ksi) Unalloyed, highly ductile titanium offering exceptional corrosion resistance in oxidizing and organic chemical environments. Used for heat exchangers and chemical piping.

Special Techniques for Titanium Fabrication

Because molten titanium reacts aggressively with atmospheric oxygen, nitrogen, and hydrogen at elevated temperatures, specialized manufacturing infrastructure is required:

  • Rammed-Graphite & Vacuum Casting: Poured in specialized vacuum induction furnaces to prevent the formation of brittle alpha-case surface layers.
  • Precision Forging Grain Alignment: Closed-die hot forging reorients the alpha-beta grain flow, maximizing cyclic fatigue resistance for high-load structural pins and landing gear hardware.
  • Chemical Passivation & Surface Treatment: Chemical pickling and passivation restore the natural, non-reactive titanium oxide skin, ensuring zero chemical reactivity in marine and medical environments.

Frequently Asked Questions

How does ForceBeyond prevent brittle alpha-case formation during titanium casting?

We utilize rammed-graphite molds and pour within specialized vacuum induction furnaces to eliminate exposure to atmospheric oxygen, nitrogen, and hydrogen at elevated temperatures.

What is the difference between Ti-6Al-4V Grade 5 and Ti-6Al-4V ELI (Grade 23)?

Ti-6Al-4V ELI contains Extra Low Interstitials (reduced oxygen and iron content), granting higher fracture toughness and superior biocompatibility, making it the preferred choice for medical implants.
