New Delhi: Lucknow-based Aerolloy Technologies Limited, a subsidiary of PTC Industries Limited has announced the award of a development and supply order
for Jeff Bezos’ owned Blue Origin based in Seattle, Washington for large superalloy investment casings for the BE-4 rocket engines, used on the first stage of the New Glenn rocket. These are heat-resistant components manufactured under a precise process, capable of operating in extreme chemical and pressure environments. The components have complex internal geometries and require defect-free metallurgical integrity, that can only be provided by a handful of foundries worldwide at the required scale.
Aerolloy’s Vacuum Induction Melting (VIM) furnace is the facility that allows for the melting and processing of the large superalloy heats under tightly controlled vacuum conditions. The contract establishes Aerolloy as a qualified supplier of orbital-class propulsion hardware, extending beyond aerospace and defence into launch vehicle engine systems, and reinforces the vertical-integration strategy by PTC from alloy production to near-net-shape castings, making it competitive globally. The award is also good for the indigenous space manufacturing ecosystem, and adds an export-oriented, high value manufacturing stream for global launch systems, and aligns with the Make in India and Atmanirbhar Bharat initiatives.
India as a trusted source for space-grade hardware
In a press release, Chairman and Managing Director of 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.”
