Does enybody know something about the AlSi17Cu4Mg material? I would like to know everthing! The most important question is the structural properties! What is the yield stress limit, UTS, Young modulus, Fatigue strength limit etc!
Look up Volume 2 of the 9th edition of "Metals Handbook"
published by ASM International (formerly American Society for Metals). Most public libraries have a copy of this book in their reference section. You will note that some of the properties you ask for will vary with temperature and other conditions in the working environment.
