Aerolloy Technologies Limited, a wholly owned subsidiary of PTC Industries Limited, has secured a development and supply order from Blue Origin for large superalloy investment castings used in the BE-4 rocket engines powering the first stage of the New Glenn orbital launch vehicle. The order covers propulsion hardware for a reusable heavy-lift launch system and marks Aerolloy’s entry into the orbital launch systems supply chain.
The scope of work includes large nickel-based superalloy castings for liquid oxygen high-pressure and low-pressure housings and manifolds required for the seven-engine BE-4 cluster on New Glenn’s first stage. These components operate under extreme thermal, chemical, and pressure conditions and require complex internal geometries and tight dimensional tolerances.
The company said the order followed an extended technical, qualification, and regulatory review process, including compliance with applicable international export control and regulatory frameworks. The review reflects the mission-critical nature of the BE-4 propulsion system and the quality and reliability requirements associated with orbital-class launch vehicles.
Aerolloy said production of the castings will be enabled by its recently commissioned vacuum induction melting furnace, which allows melting and processing of large superalloy heats under controlled vacuum conditions. The facility provides the metallurgical base required for producing large, high-integrity investment castings used in advanced propulsion systems.
New Glenn is a reusable heavy-lift orbital launch vehicle that reached orbit on its inaugural flight in January 2025. Its first stage is powered by seven BE-4 engines, each delivering approximately 550,000 pounds-force, or about 2,450 kilonewtons, of thrust. The superalloy liquid oxygen housings and manifolds supplied under the programme are described as mission-critical components that directly affect engine performance, safety, and reusability.
“Blue Origin’s selection of Aerolloy for BE-4 engine hardware marks a defining milestone in our entry into space propulsion systems,” said Sachin Agarwal, Chairman and Managing Director of PTC Industries Limited. “The award of this order, following extensive qualification and regulatory review, validates Aerolloy’s ability to deliver large, high-integrity superalloy investment castings, enabled by our recently commissioned vacuum induction melting furnace.”
PTC Industries Limited is an Indian manufacturer of precision metal components for critical and high-performance applications. Through its wholly owned subsidiary Aerolloy Technologies Limited, the company manufactures and supplies titanium and superalloy materials and castings for aerospace and defence applications for domestic and international customers.
