PTC Industries Limited’s wholly owned subsidiary, Aerolloy Technologies, has successfully commissioned a state-of-the-art Vacuum Arc Remelting (VAR) 400 Furnace at its Aerospace Precision Castings Plant in the Strategic Materials Technology Complex (SMTC), Lucknow. This milestone installation empowers Aerolloy with the capability to produce some of the world’s largest aerospace-grade titanium castings, positioning India among a select group of countries with such advanced manufacturing prowess.
Advanced VAR Technology Powers Aerospace Excellence
The newly installed VAR furnace, German-engineered with an annual melting capacity of 1,500 metric tons, enables Aerolloy to produce titanium alloy ingots with superior metallurgical structure and enhanced uniformity. The furnace can cast ingots weighing up to 10 metric tons and measuring up to 1,000 mm in diameter, crucial specifications for forming critical aeroengine and defense components.
VAR is a high-precision remelting process executed under vacuum to eliminate impurities and ensure premium alloy homogeneity. This technology is essential for manufacturing durable, high-performance materials used in jet engines, industrial gas turbines, and aerospace airframes.
Closing the Strategic Manufacturing Gap for India
The commissioning fulfills a significant gap in India’s strategic manufacturing capabilities, reducing dependence on imports and enhancing self-reliance in producing critical aerospace materials. Aerolloy becomes one of only a handful of global suppliers capable of producing double-melt quality titanium alloy ingots, a benchmark in the aerospace industry.
Chairman and Managing Director Sachin Agarwal emphasized, “This is a defining moment for Aerolloy and India’s defense and aerospace sectors. Our VAR facility places India on the global map for aerospace-grade titanium production, a capability previously limited to a few nations.”
Integrated Manufacturing and Market Opportunities
Aerolloy’s VAR furnace complements its existing Vacuum Induction Melting (VIM) facilities, establishing a fully integrated production line from raw alloy production through near-net-shape precision castings. This integration is expected to enhance operational efficiencies, reduce costs, and strengthen supply chain reliability for aerospace and defence customers worldwide.
The company holds multi-year agreements with global aerospace leaders including Dassault Aviation, Safran Aircraft Engines, and Israel Aerospace Industries (IAI) to supply critical titanium and superalloy castings, underscoring increasing market confidence.
Strategic Importance Amid Global Aerospace Growth
The global superalloy market, valued over $15 billion annually, is expanding rapidly driven by aerospace, defense, space exploration, and industrial gas turbine demands. Aerolloy’s new capabilities position it to capture a growing share of this market, offering India a strategic advantage.
The UP Defence Industrial Corridor at Lucknow, designed to foster advanced manufacturing industries, provides Aerolloy critical infrastructure and ecosystem support, further boosting India’s ambitions in high-tech industrial sectors.
