RT Journal Article SR Electronic A1 Střihavková, Elena T1 Analysis of Machinability of New AlSi7Mg0.3 Alloys with Different Calcium Content JF Manufacturing Technology Journal YR 2018 VO 18 IS 4 SP 679 OP 685 DO 10.21062/ujep/160.2018/a/1213-2489/MT/18/4/679 UL https://journalmt.com/artkey/mft-201804-0028.php AB The field of application of aluminium alloys is very wide and the future use of aluminium alloys is related to the further development of new alloys. Recently, the use of alloys in aluminium alloys is a trend in achieving changes in chemical, mechanical and technological properties. This paper deals with the investigation of the area of calcium influence, especially on the machinability of the alloy. The analysis was performed by alloying AlSi7Mg0.3 with master alloy AlCa10. Four types of samples with different calcium content, from at least 0.1% Ca, up to 1% Ca maximum, were produced. In the case of such samples, research was carried out on the technological properties and especially the workability.
