Magnesium, a light-weight metal, has been used as a construction material since the early days of the 20th century. Excellent availability and low specific weight are the main benefits for applications in the aerospace and automotive fields. Due to its limited corrosion stability, its range of applications had been limited until the 1980's of the last century.
This problem was solved by the development of new alloys. Now questions are arising concerning casting, machining and joining magnesium workpieces.
In 1996 an interdisciplinary research project called “Madica” was launched in Germany to answer these questions. That project, sponsored by the German Ministry of Education and Research, or “BMBF”, was designed to cover the whole production chain, from diecasting up to the finished workpiece. The basic know-how resulting has been encouraging German industry to abandon any hesitation about using magnesium in applications where the material benefits will meet market requirements.
Metal-working fluids have always been an essential tool for efficient processing at most mass production machining plants. The basic know-how for safe and economically efficient application of cutting fluids in the machining of Mg-alloys was worked out in one of “Madica's” subprojects. This has produced not only a handling guideline but also newly developed fluid systems.
Specially adapted multi-purpose oil systems are suited to meet all the specific requirements posed by magnesium. Laboratory results and field applications are demonstrating that it is possible to control the huge problems of the past, such as hydrogen formation, emulsion split and corrosion.
