Machinability of modified AlSi7Mg0,3 alloy

Al Alloys have an important position in the industry, mainly in the automotive and aerospace industries. One important group is silumins (Al - Si alloys). Al - Si alloys are the leading casting alloys based on aluminum. Machining of aluminum alloys is currently frequently used and it is an i mportant area of production. This paper deals with an experiment that was conducted at the Faculty of Production Techno l- o gy and Management, University of Jan Evangelista Purkyně in Ústí nad Labem, where alloy AlSi7Mg0,3 was experimented upon . Samples were made for processing from the master alloy AlSi7Mg0,3, subsequently unmodified and modified of Sr, Ca and Sb. This paper d escribes the evaluation of hardness, chip and tool wear in terms of how modification by Sr, Ca and Sb may affect analytical values.
