Description:
In K424 nickel based cast super alloy, the content of Al and Ti is high while the density is low, which makes it a high temperature strength, plasticity and good manufacturability. It is suitable for making turbine rotor blades, integrally casted turbine and engine parts and so on.
Density: 7.87g/cm³
Melting Range: 1271~1310º C
