Changes

Soon after it's its founding in 1922 Electrical Contacts became the focal world for DODUCO. Inthe previous two editions of the DODUCO Data Book this world was mostly limited toEurope. Since expanding its reach globally from the 1970s through the 1990s, including thestart-up of manufacturing operations in China, the employees of AMI DODUCO haveconcentrated on solving electrical contact problems around the world as the main task oftheir daily work.Ever increasing requirements on the performance of contacts in electrical switching devices,the need for highly reliable interconnections between electro-mechanics and electronics, theminimizing of precious metal usage, and the call for more environmentally compatiblematerials and manufacturing processes, defined in the past years the development ofmaterials and technologies related to electrical contacts. These latest developments andrepeated requests from our customers were the motivation to publish a new edition of update thewell known DODUCO Data Bookby the Electrical Contacts Wiki. It includes now also materials whose properties andapplications are mostly relevant in the North American and Asian markets. We also includedmaterials which are needed for the manufacturing of contact parts and assemblies, but areoutside of AMI DODUCO's product offerings. These include contact carrier materials such ascopper and nickel alloys, as well as thermostatic materials and brazing alloys. Even so , we felt it was necessary to add more detailed descriptive passages about productsand technologies, which expanded the original focus on mostly data tables anddiagrams, we continue to keep the name Data Book. We updated and re-wrote mostchapters for the third edition but changed to a slightly larger format of the book in orderto improve its ease of useData Book. We also expanded and updated the references at the end ofeach chapter which are meant to aid those readers who want to benefit from more anddeeper detailed published resources.The third edition was published in English in 2010 under the name AMI DODUCO.Since later in that year our company is owned by the investment groups TinicumCapital Partners II and JP Asia Partners and again is registered under the former nameof DODUCO, however using a new corporate identity and image. This event served asthe reason to again revise the Data Book and publish the latest version under the wellknown corporate name of DODUCO.This new DODUCO Data Book updated Electrical Contacts Wiki again is meant to be a handy reference and data sourcefor all those who need to work in the field of electrical contacts and their applications. Itcan however not be a full substitute for personal discussions with experts in electricalcontact technology. For such technical exchanges we offer the direct expertise andadvice from our application engineers and research and development staff who areready to answer your questions.-  Please challenge us with your unique problems or special requests; , because ourworld is the World of Electrical Contacts.  The EditorsDODUCOPforzheim, Germany, May 2012February 2023
