Aerolloy Technologies Limited, a wholly owned subsidiary of PTC Industries Limited and a manufacturer of high-precision metal components and materials for critical and super-critical applications, today announced the award of a development and supply order from Blue Origin for the manufacture of large Superalloy investment castings for the BE-4 rocket engines used on the first stage of New Glenn.

The award of this order follows a prolonged technical, qualification, and regulatory review process, including compliance with applicable international export control and regulatory frameworks, reflecting the highly sensitive and mission-critical nature of the BE-4 propulsion system.

Under this programme, Aerolloy will produce large Nickel-based Superalloy housings and manifolds required for Liquid Oxygen (LOX) high-pressure and low-pressure systems. These components operate under extreme thermal, chemical, and pressure environments, demanding tight dimensional control, complex internal geometries, and defect-free metallurgical integrity, a combination that only a handful of global foundries can reliably achieve at this scale.

A key enabler for this order is Aerolloy's Vacuum Induction Melting (VIM) furnace, recently commissioned and previously disclosed. This facility allows melting and processing of large Superalloy heats under tightly controlled vacuum conditions, forming the metallurgical foundation for large, high-integrity investment castings required in advanced propulsion systems.

Programme significance

For Blue Origin's New Glenn programme

New Glenn is Blue Origin's reusable heavy-lift orbital launch vehicle, which successfully reached orbit on its inaugural flight in January 2025. Its first stage is powered by seven BE-4 engines, each delivering approximately 550,000 lbf (~2,450 kN) of thrust.

The Superalloy LOX housings and manifolds supplied by Aerolloy are mission-critical components, directly impacting engine performance, safety, and reusability. Their manufacture represents one of the most technically challenging aspects of the BE-4 propulsion system.

By engaging Aerolloy, Blue Origin gains:

– Access to one of the very few global manufacturers capable of producing large Superalloy investment castings for orbital-class engines

– Supply-chain resilience through an integrated manufacturing route, from Superalloy melting to casting and downstream processing

– A partner capable of supporting production ramp-up and long-term programme evolution as New Glenn moves toward regular launch cadence

For Aerolloy Technologies and PTC Industries

– Establishes Aerolloy as a qualified supplier for orbital-class propulsion hardware, extending beyond aerospace and defence into launch-vehicle engine systems

– Leverages Aerolloy's large-format investment casting, vacuum melting, NDT, and process-control infrastructure for high-reliability space applications

– Reinforces PTC's vertical-integration strategy, from alloy production to near-net-shape castings, enabling competitiveness in globally scaled programmes

For India's space manufacturing ecosystem:

– Represents a step-change in indigenous capability for high-complexity propulsion hardware

– Adds an export-oriented, high-value manufacturing stream for global launch systems

– Aligns with Make in India and Atmanirbhar Bharat objectives while integrating India into the global space supply chain

Mr. Sachin Agarwal, Chairman & Managing Director, PTC Industries Limited, said:

"Blue Origin's selection of Aerolloy for BE-4 engine hardware marks a defining milestone in our entry into space propulsion systems. The BE-4 is among the most advanced engines in operation today, and New Glenn's performance requirements set an exceptionally high bar for quality and reliability.

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 VIM furnace, one of the largest of its kind globally.

We are proud to contribute to a program that is shaping the future of access to space, while strengthening India's position as a trusted source for critical, space-grade hardware."
