Atomfair GH4099 Nickel-Based Superalloy Powder (SLM Grade)

Institutional Procurement & Supply Compliance: As a verified US supplier, Atomfair accepts formal institutional Purchase Orders (POs), contract billing schedules, and custom procurement loops for university and national laboratories, and corporate R&D departments globally.

GH4099 is a Ni-based precipitation-hardened superalloy, suitable for long-term service below 900°C and short-term use up to 1000°C. It exhibits excellent thermal strength and good hot/cold work formability, making it ideal for high-temperature welded structural components like aero-engine combustion chambers and afterburners. Compatible with the SLM process.
