Alcoa industrial gas turbine blades and vanes
Alcoa, Pittsburgh, Pa., announces that Alcoa Power and Propulsion (APP) has signed a long-term agreement with Siemens Energy to supply investment-cast blades and vanes for a wide range of industrial gas turbines. Alcoa parts made in the U.S. and Europe will be used in the Siemens F-Class turbine, which generates enough power to supply the energy needs of a city of 300,000 residents.
“Alcoa’s blades and vanes operate in the most demanding section of the turbine, where temperatures sometimes exceed the melting point of the casting and the rotational rate exceeds the speed of sound,” said Andreas Fischer-Ludwig, Director of Global Blades & Vane Business at Siemens Energy. “But even in that severe environment, Alcoa technology keeps the castings working optimally, which is crucial to our global customers who need to generate electricity dependably.”
