Dyno Tested & Track Oriented

Grade 5 Titanium (Ti-6Al-4V) hardness varies with processing but typically falls around 330-370 BHN (Brinell) or Rockwell C 30-39, offering a good balance of strength and lightweight properties for aerospace, medical implants, and high-performance parts, though it has poor surface wear compared to other metals without treatment.
Typical Hardness Values:
Brinell Hardness (BHN): 326 – 379
Rockwell Hardness (C Scale): Around C30-34 (annealed) to C35-39 (solution treated & aged)
Key Factors Influencing Hardness:
Heat Treatment: Can be heat-treated (annealed, solution treated & aged) to adjust strength and hardness.
Processing: Forging and other processing methods affect the final hardness.
Characteristics:
High Strength: Stronger than Grade 2, making it a “workhorse” for aerospace.
Good Corrosion Resistance: Excellent against seawater and alkalis.
Poor Wear Resistance: Prone to seizing in sliding contact, often requiring surface treatments like nitriding.
