Product Overview
The AeroForge-TD750 Forged Turbine Disc is a high-integrity, NADCAP-certified aerospace component engineered for extreme rotational speeds, thermal cycling, and fatigue-critical applications in modern gas turbine engines. With a nominal diameter of Ø750mm and thickness of 120mm, this precision-forged disc is manufactured from premium-grade Inconel 718 alloy (AMS 5662), delivering exceptional strength-to-weight ratio, oxidation resistance up to 650°C, and outstanding creep resistance. As a premier solution among forged turbine discs, the AeroForge-TD750 undergoes fully traceable, vacuum-controlled heat treatment per AMS 2750 and is certified under NADCAP Heat Treat — ensuring zero compromise on microstructural uniformity and mechanical reliability.
Designed for OEM and Tier-1 engine integrators, this disc exemplifies advanced near-net-shape forging, minimizing material waste while maximizing grain flow alignment along critical stress paths — a hallmark of high-performance aerospace turbine discs. Its precise dimensional stability and surface integrity meet stringent NAS 410 and AS9100 requirements for flight-critical rotating assemblies.

Applications
The AeroForge-TD750 is purpose-built for aerospace turbine discs in high-pressure compressor (HPC) and low-pressure turbine (LPT) modules of civil and military jet engines (e.g., CFM LEAP, GE9X, F135 derivatives). It serves as a drop-in replacement or upgrade disc for legacy systems requiring enhanced durability and extended service life. Beyond aviation, it supports demanding applications in industrial gas turbines, power generation turbomachinery, and high-speed test rigs where Inconel 718 turbine disc performance and Ø750mm turbine disc scalability are mission-critical. As part of our custom forging portfolio, the AeroForge-TD750 enables rapid prototyping, low-volume production, and full configuration control — empowering engineering teams to accelerate certification timelines without sacrificing metallurgical fidelity.
