This FAQ addresses the most common technical, commercial, and handling questions regarding Titanium Grade 5 (Ti-6Al-4V) rods.
1. Material & Performance

What is the difference between Grade 5 and "ELI" Grade 5? Grade 5 is the standard aerospace alloy. Grade 5 ELI (Extra Low Interstitial), or Grade 23, is a higher-purity version with lower levels of oxygen, nitrogen, and iron. ELI is primarily used for medical implants because it offers better ductility and fracture toughness.

Is Grade 5 titanium stronger than Grade 2? Yes, significantly. Grade 5 has a tensile strength of approximately 950 MPa, which is nearly triple the strength of Commercially Pure Grade 2 (~345 MPa).

Can Grade 5 titanium rods be heat treated? Yes. Unlike the CP grades, Grade 5 is an alpha-beta alloy that can be solution treated and aged (STA) to increase its hardness and strength even further.
2. Applications & Industry

Why is Grade 5 used in aerospace engines? It maintains high strength at temperatures up to 400°C and has excellent fatigue resistance. This makes it ideal for rotating parts like compressor blades and high-strength fasteners.

Is it suitable for marine environments? Absolutely. Grade 5 is virtually immune to corrosion in seawater. It is used for subsea pressure housings and propeller shafts where the weight of steel would be prohibitive.

Can it be used for dental or medical implants? Yes. Grade 5 (specifically the ELI/Grade 23 version) is the industry standard for dental posts and orthopedic screws due to its biocompatibility and its ability to bond with bone (osseointegration).
3. Machining & Fabrication

Is Grade 5 titanium difficult to machine? Compared to steel or aluminum, yes. It has low thermal conductivity, meaning heat builds up at the cutting edge.

    Best Practice: Use sharp carbide tools, low cutting speeds, and high-pressure coolant.

Can Grade 5 rods be welded? Yes, but they are highly reactive to oxygen. Welding must be done under a strict Argon gas shield (TIG, Plasma, or Laser welding) to prevent the weld from becoming brittle.

Does Grade 5 titanium gall? Yes. Titanium has a tendency to "gall" or cold-weld to other surfaces under pressure. If you are using Grade 5 rods for threaded fasteners, it is essential to use an anti-seize lubricant or specialized coatings.
4. Technical Specs & Standards

What are the most common specifications for these rods?

    Aerospace: AMS 4928, AMS 4967.

    Industrial: ASTM B348.

    Medical: ASTM F136 (for ELI/Grade 23).

What is the density of Grade 5? It is 4.43 g/cm³. For reference, this makes it about 45% lighter than stainless steel.
