Incoloy 907

Incoloy 907 is a high-performance iron-nickel-cobalt alloy designed for demanding high-temperature applications. Enhanced with niobium, titanium, silicon, and trace boron, it offers exceptional precipitation hardening, resulting in superior strength and low thermal expansion. This alloy maintains stable mechanical properties and structural integrity under prolonged exposure to temperatures up to 650°C. Its excellent resistance to both cold and hot fatigue makes it ideal for dynamic load components operating in high-pressure, high-temperature environments. Incoloy 907 ensures reliable performance where durability and dimensional stability are critical.
