Aerolloy Technologies Limited, a wholly owned subsidiary of ptc industries , has announced a significant milestone with the award of a development and supply order from Blue Origin for large superalloy investment castings for the BE-4 rocket engines used on New Glenn's first stage.

Strategic Entry into Orbital Launch Systems

The order represents Aerolloy's strategic entry into orbital launch systems, focusing on critical propulsion hardware for Blue Origin's heavy-lift orbital launch vehicle. The scope encompasses large Nickel-based superalloy castings for Liquid Oxygen (LOX) high-pressure and low-pressure housings and manifolds, essential components for the seven-engine BE-4 cluster powering New Glenn's first stage.

Technical Capabilities and Global Positioning

The award follows completion of extensive qualification and applicable international regulatory and compliance processes, reflecting the highly sensitive and mission-critical nature of the BE-4 propulsion system. Very-large vacuum investment castings in superalloys for orbital-class engines are produced by only a very limited number of companies worldwide, highlighting the extreme technical and quality barriers involved.

These components operate under extreme thermal, chemical, and pressure environments, demanding tight dimensional control, complex internal geometries, and defect-free metallurgical integrity. The castings will be enabled by Aerolloy's recently commissioned Vacuum Induction Melting (VIM) furnace, among the largest VIM furnaces in operation globally, specifically designed to support such large superalloy castings.

Program Significance

Blue Origin's New Glenn Program

New Glenn is Blue Origin's reusable heavy-lift orbital launch vehicle, which successfully reached orbit on its inaugural flight in January 2025. The superalloy LOX housings and manifolds supplied by Aerolloy are mission-critical components, directly impacting engine performance, safety, and reusability.

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, along with supply-chain resilience through an integrated manufacturing route from superalloy melting to casting and downstream processing.

Impact on India's Space Manufacturing Ecosystem

The order represents a step-change in indigenous capability for high-complexity propulsion hardware and adds an export-oriented, high-value manufacturing stream for global launch systems. This development aligns with Make in India and Atmanirbhar Bharat objectives while integrating India into the global space supply chain.

Leadership Commentary

Mr. Sachin Agarwal, Chairman & Managing Director of PTC Industries Limited, emphasized the milestone's significance: "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."

He further noted that the award validates Aerolloy's ability to deliver large, high-integrity superalloy investment castings, enabled by the recently commissioned VIM furnace, one of the largest of its kind globally.

Strategic Infrastructure Development

PTC Industries is significantly expanding its capabilities through a multi-million-dollar investment in its Strategic Materials Technology Complex (SMTC) at the Lucknow node of the Uttar Pradesh Defence Industrial Corridor. The facility is being developed as a fully vertically integrated ecosystem, encompassing aerospace-grade titanium and superalloy melting and mill operations, producing ingots, billets, bars, plates, and sheets, along with state-of-the-art precision casting and downstream manufacturing capabilities.

Through this integrated approach, PTC is building one of the most advanced end-to-end platforms globally for strategic materials and flight-critical components, strengthening India's role in the global aerospace and defence supply chain.

PTC Industries has announced a significant development in its aerospace operations, with its subsidiary Aerolloy Technologies securing an order from Blue Origin, the aerospace company founded by Jeff Bezos.

Order Details and Scope

The contract involves supplying specialized components for Blue Origin's BE-4 engine program. Aerolloy Technologies will manufacture and deliver superalloy investment castings, which are critical components used in advanced rocket propulsion systems.

Strategic Significance

This order represents a notable milestone for Aerolloy Technologies, as it confirms the company's position as a trusted supplier for orbital-class propulsion equipment. The BE-4 engine is a crucial component in Blue Origin's rocket systems, and securing this contract demonstrates Aerolloy's capabilities in manufacturing high-precision aerospace components.

About the Components

Superalloy investment castings are specialized manufacturing products that require advanced metallurgical expertise and precision engineering. These components are essential for rocket engines operating under extreme conditions, including high temperatures and pressures encountered during space missions.

The partnership with Blue Origin adds to PTC Industries' growing presence in the aerospace sector through its subsidiary Aerolloy Technologies, positioning the company as a key supplier in the commercial space industry.
