But step change can be achieved via co-optimization of design, material, manufacturing. Driven by the evolution of regulation towards reducing CO2 emissions of cars, and by the competition with other materials in aerostructures, Aluminium has a fantastic but challenging growth opportunity. CONSTELLIUM has defined automotive and aerospace as one of his key strategic segments, and is actively addressing those challenges through strong R&D capabilities: Developing an appropriate portfolio of alloys along key technical drivers and pursuing with more step-change concepts Partnering with OEMs to develop affordable solutions All this with sustainability in mind 17/06/2016 18.

  • Department of Justice Will Require a Divestiture If Alcan Inc. Completes Its Pending Tender Offer for Pechiney S.A
    FOR IMMEDIATE RELEASE AT MONDAY, SEPTEMBER 29, 2003 (202) 514-2007 WWW.USDOJ.GOV TDD (202) 514-1888 DEPARTMENT OF JUSTICE WILL REQUIRE A DIVESTITURE IF ALCAN INC. COMPLETES ITS PENDING TENDER OFFER FOR PECHINEY S.A. Sale of Pechiney’s Ravenswood, West Virginia, Aluminum Rolling Mill and Related Assets Will Preserve Competition in the North American Market for Brazing Sheet WASHINGTON, D.C. – The Department of Justice reached a settlement today with Alcan Inc. that requires Alcan to divest Pechiney S.A.’s aluminum rolling mill in Ravenswood, West Virginia, if Alcan’s pending $4.6 billion tender offer for Pechiney is successful. The tender offer, publicly announced in early July and recently endorsed by Pechiney’s board of directors, is expected to be completed in late November 2003. The Department said that the acquisition, as originally proposed, would substantially lessen competition in the development, production, and sale of brazing sheet, an aluminum alloy used in fabricating radiators, oil coolers, heaters, and air conditioning units for motor vehicles, and would likely result in higher prices. The Department’s Antitrust Division filed a lawsuit today in U.S. District Court in Washington, D.C. to block the original transaction. At the same time, the Department filed a proposed consent decree that, if approved by the court, would resolve the Department's competitive concerns and the lawsuit. “The divestiture of Pechiney’s Ravenswood mill will preserve competition for brazing sheet sold in North America, and will allow motor vehicle parts manufacturers to benefit from Alcan’s aggressive competition,” said R. Hewitt Pate, Assistant Attorney General in charge of the Department’s Antitrust Division.

JUDGE: Gladys Kessler ALCAN INC., 1188 Sherbrooke Street West DECK TYPE: ANTITRUST Montreal, Quebec, Canada H3A 3G2; DATE: September 29, 2003 ALCAN ALUMINUM CORP., 6060 Parkland Boulevard Cleveland, OH 44124-4185; PECHINEY, S.A., 7, Place Du Chancelier Adenauer CEDEX 16 – 75218 – Paris France; and PECHINEY ROLLED PRODUCTS, LLC, Rural Route 2 Ravenswood, WV 26164-9802, Defendants. COMPLAINT The United States of America, acting under the direction of the Attorney General of the United States, brings this civil antitrust action to obtain equitable relief against defendants, and alleges as follows: 1. In early July 2003, Alcan Inc. (“Alcan”) launched a $4.6 billion tender offer for Pechiney, S.A. (“Pechiney”), which was later endorsed by Pechiney’s board of directors. The United States seeks to enjoin this proposed acquisition, which, if consummated, would result in consumers paying higher prices for brazing sheet, an aluminum alloy used in making heat exchangers for motor vehicles. 2. Alcan, through its United States subsidiary (Alcan Aluminum Corp.), and Pechiney, through its United States subsidiary (Pechiney Rolled Products, LLC), are, respectively, the second and fourth largest producers of brazing sheet in North America. Brazing sheet consists of a class of layered aluminum alloys, each of which has a unique ability to form a uniform, durable, leak-proof bond with other aluminum surfaces. Brazing sheet is widely used in fabricating the major components of heat exchangers for motor vehicles, including engine cooling (e.g., radiators and oil coolers) and climate control (e.g., heaters and air conditioners) systems.

  • Iron-Rich Bauxite and Bayer Red Muds Yingyi Zhang, Yuanhong Qi and Jiaxin Li
    Chapter Aluminum Mineral Processing and Metallurgy: Iron-Rich Bauxite and Bayer Red Muds Yingyi Zhang, Yuanhong Qi and Jiaxin Li Abstract Bauxite is the main source for alumina production. With the rapid development of iron and steel industry and aluminum industry, high-quality iron ore and bauxite resources become increasingly tense. However, a lot of iron-rich bauxite and Bayer red mud resources have not been timely and effectively recycled, resulting in serious problems of environmental pollution and wastage of resources. The com- prehensive utilization of iron-rich bauxite and red mud is still a worldwide problem. The industrial stockpiling is not a fundamental way to solve the problems of iron- rich bauxite and red mud. As to the recovery of valuable metals from iron-rich bauxite and red mud, there are a lot of technical and cost problems, which are serious impediments to industrial development. Applying red mud as construction materials like cement, soil ameliorant applications face the problem of Na, Cr, As leaching into the environment. However, the high-temperature reduction, smelting and alkaline leaching process is a feasible method to recover iron and alumina from iron-rich bauxite and red mud. This chapter intends to provide the reader an overview on comprehensive utilization technology of the low-grade iron-rich bauxite and Bayer red mud sources. Keywords: bauxite, iron-rich bauxite, Bayer red mud, Bayer process, magnetic separation, reduction and smelting process 1. Introduction With 8.30%, aluminum is the third element in the earth’s crust after the oxygen and the silicon, and for that reason, aluminum minerals are abundant with more than 250 kinds.
