TC4 (TC4 ELI) GR5 Titanium Alloy

TC4 Titanium Alloy Overview

TC4, or Ti-6Al-4V, is an (α+β) type titanium alloy known for its excellent comprehensive mechanical properties. It features a high specific strength and low thermal conductivity, making it a versatile material in various industries.

  • Specific Strength:
    • Tensile strength (σb\sigma_b) - 1.012 GPa
    • ความหนาแน่น (gg) - 4.51 g/cm³
    • Specific strength (σb/g\sigma_b/g) - 23.5
    • For comparison, alloy steel’s specific strength (σb/g\sigma_b/g) is less than 18.
  • Thermal Conductivity:
    • TC4’s thermal conductivity (λ\lambda) - 7.955 W/m·K
    • This is 1/5 that of iron and 1/10 that of aluminum.
