Alcoa (NYSE: AA) today announced that Alcoa Power and Propulsion (APP) has signed a long-term agreement with Siemens Energy to supply blades and vanes for a wide range of industrial gas turbines. Siemens Energy is one of the world’s leading suppliers of products, solutions and services in the energy technology field. Contract terms were not disclosed. Alcoa parts made in the U.S. and Europe will be used in, among others, 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.” “We are pleased that Siemens Energy recognizes the value Alcoa’s expertise in investment casting brings to building efficient and durable power generation equipment,” said Allen Zwierzchowski, Vice President, APP. “As a global leader in investment castings, we are well-positioned to support demand for industrial gas turbines as power suppliers use greater amounts of low-priced natural gas to produce electricity.” The Alcoa contract builds upon a 30-year relationship with Siemens and provides the opportunity to collaborate on technology to further improve industrial gas turbine performance.
