Comparison of tribological properties of steel and Al-alloys sheet metals intended for deep drawing

Abstract

During the last few years, aluminum alloys are increasingly more used in production of light constructions, especially for manufacture of light car bodies of passenger cars. From the aspect of tribological factors influence, experience in application of low carbon steel sheet metals in manufacture of car body parts by deep drawing procedures up to now differs significantly regarding the application of Al alloys. The paper presents the results of tribological investigations of specified materials properties at sliding tests, as well as results at deep drawing with variable blank holding force.
