Intermet awarded patent for new ferrous material.Intermet Corp.'s Domestic Ferrous ferrous (fĕr`əs), iron in the +2 valence state. Containing or having to do with iron. The difference between ferrous and ferric is the number of valence electrons they contain (ferrous contains two and ferric contains three), which Group, Troy, Mich., has been awarded a patent from the U.S. Patent & Trademark Office for machinable austempered ductile iron Ductile iron, also called ductile cast iron or nodular cast iron, is a type of cast iron invented in 1943 by Keith Millis[1]. While most varieties of cast iron are brittle, ductile iron is much more ductile, as the name implies. (MADI MADI Multichannel Audio Digital Interface MADI Movimento de Apoio Ao Diminuído Intelectual (Movement of Support to the Mentally Handicapped - Portugal) MADI Massachusetts Destination Imagination (youth program) ), a new ferrous material that provides improved strength compared to traditional ductile iron, as well as improved machinability and fatigue performance over austempered ductile iron. "Because the design strength of MADI is 50 to 100% higher than current as-cast ductile irons, significantly lighter weight components can now be designed," said Dr. Alan Druschitz, technical manager at Intermet's Archer Creek Foundry A semiconductor manufacturer that makes chips for third parties. It may be a large chip maker that sells its excess manufacturing capacity or one that makes chips exclusively for other companies. , Lynchburg, Va., and co-developer of MADI. The patent (U.S. Patent No.7,070,666, issued July 4, 2006) covers key elements of the new material and the method of manufacture, including a proprietary heat-treatment process. MADI was developed by Intermet in 2001 at the research metalcasting facility in Lynchburg for casting automotive structure and powertrain components, such as control arms, steering The process whereby builders, brokers, and rental property managers induce purchasers or lessees of real property to buy land or rent premises in neighborhoods composed of persons of the same race. knuckles and crankshafts. Intermet currently has MADI vehicle control-arm and steering-knuckle programs in production at its Archer Creek Foundry. |
