Abstract
This article provides an overview of the materials used to manufacture magnesium wheels for light vehicles. The analysis was conducted with the aim of developing a new, efficient technology for molding magnesium alloy wheels for light vehicles from preforms cast into metal molds. The knowledge accumulated so far on materials and their properties for the production of magnesium wheels will allow the design of a new technology for molding rims from materials of superior quality and durability. Currently, magnesium wheels are mainly produced from cast magnesium alloys and magnesium alloys for forming. Cast magnesium alloys used for magnesium wheels include AZ91, AM50, AM60, AE44, ZK61, ZE41, EZ33, EQ21, WE43 and the newly developed Mg-2.96Nd-0.21Zn-0.39Zr alloy. Magnesium metal-forming alloys used for magnesium wheels include AZ31, AZ61, AZ80 and ZK30, ZK60. The study includes an analysis of their properties and application examples.
