DTL produces ingots by vacuum melting material returned by the customer and new material according to the customer's specifications.
Our main products are nickel- and cobalt-based alloy ingots for vacuum melting and precision casting.
The major applications of our ingots are jet engines for aircraft, turbochargers for automobiles, and industrial gas turbines.
Typical nickel based master alloy ingots' grades like: K418(IN713),K4169,GH4099,K4648,K424,IN738,GH4169,GH3536,GH3625,M247,etc.,
Diameter: 250~8100mm , length: 120~700mm
