Kobe Steel furnishes its double-melt Ti-6Al-4V titanium alloy rings to Kawasaki Heavy Industries, which proces易游m6在线登录入口s the metal into intermediate pressure compressor casings. The completed casings are then shipped to Rolls-Royce for fabrication in the Trent 900 engine.

The initial shipment began in January this year. Over an initial five-year period, Kobe Steel will be the sole supplier of titanium rings to Kawasaki for the casings of the Trent 900 engine, with Kawasaki the sole supplier of the casings to Rolls-Royce. Kobe Steel's 易游m6在线登录入口ny years of collaboration with Kawasaki were instrumental in gaining the order from Rolls-Royce.

The Trent 900 engine is the launch engine for the A380 and will be u易游m6在线登录入口d on 48 per cent of the aircraft already on order, according to Rolls-Royce. So far, Airbus has 129 firm orders for the 555-易游m6在线登录入口at A380.

Rolls-Royce u易游m6在线登录入口s Kobe's titanium to manufacture
compressor disks for IAE V2500 jet 易游m6在线登录入口gine

Kobe Steel, Ltd. is supplying Rolls-Royce with titanium forgings u易游m6在线登录入口d in high pressure compressor disks for the IAE V2500 engine, the engine of choice for Airbus A320 family aircraft.
