Product title: Materials Handbook (Handbook)
Product description: Anytime a title can pass through fifteen editions, it must be doing something right, and it must be providing a valuable service. While McGraw-Hill has not made volume data available, the fact that this title has been published in numerous editions since 1956 allows for its place as a compulsory read, if not as an important reference. The subtitle of the book actually describes its place rather well: "An encyclopedia for Managers, Technical Professionals, Purchasing and Production Managers, Technicians and Supervisors." The book is divided into two parts, Materials -- Their Properties and Uses; and Structure and Properties of Materials. Either part can provide valuable insights into the nature of the materials used in the battery industry daily; both together provide interesting reading and a ready reference for those numerous questions which always arise at just the wrong moment., "...the leading reference work of this kind in the world." -- Sci-Tech News, "...an ideal resource for anyone involved with materials applications, analysis, or procurement." -- Harper's Review, "This book...has saved me countless hours of library research, telephone calls, etc.; it is a storehouse of knowledge--each entry a concise gem." -- The Microscope, (Reviews are of prior editions.), THE INDUSTRY "BIBLE" SINCE 1929--WITH OVER 15,000 MATERIALS AND 30 PERCENT NEW INFORMATION! Offering comprehensive information on virtually every material and substance used in industry and engineering, Materials Handbook is unquestionably the world's favorite one-volume encyclopedia on the subject. For over six decades, there has been no better or more reliable way to get essential data on generic, patented, and trade name materials., THE NEW FIFTEENTH EDITION PROVIDES: * A-Z organization for easy access * Coverage of more than 15,000 materials * Details on chemicals, minerals, fuels, textiles, synthetics, pharmaceuticals, elastomers, ceramic coatings, industrial substances, food-stuffs, natural plant and animal substances, and--chewing gum * Thousands of new technologies and products * Properties and characteristics of materials, including composition, production methods, uses, and commercial designations or trade names * A thorough index for finding the material you want--quickly and easily
