Proterial, Ltd. (hereinafter, “Proterial”) will exhibit its products at the 55th Paris Air Show at the Le Bourget Airport that will be held in a suburb of Paris, France from June 16 to June 22, 2025. The Paris Air Show is held every other year, alternating with the Farnborough International Airshow that takes place in Farnborough, England. It is one of the world’s largest international exhibitions for aviation and aerospace devices, and celebrates its 55th anniversary this year. Proterial exhibits its products designed for aircraft engines and turbine generators, as a member of the Society of Japanese Aerospace Companies (SJAC), at its booth (CD-63, HALL 4).
1. Background and overview
Proterial regards the aviation field as one of its core growing businesses.
At this coming Paris Air Show, it exhibits low-pressure turbine (LPT) shaft*1 in nickel alloys designed for aircraft engines produced by applying a near-net shape*2 manufacturing technique. To showcase its ability to manufacture large-size components required in large aircraft engines and microstructure control capabilities, it also exhibits a blade in titanium alloys designed for turbine generators produced by Japan Aeroforge Ltd., a company partly financed by Proterial, using the 50,000-ton hydraulic forging press, one of the largest in the world.
Proterial participates in the exhibition to showcase its advanced metallurgical technologies and manufacturing techniques, which should enhance its presence in the global market and help develop the aviation industry further.
