Magnetic Susceptibility of Zr-Cu Binary Alloys

The objective of this study is to investigate the magnetic susceptibility of Zr-Cu binary alloys for their potential use as biomaterials with nullifying magnetic properties for magnetic resonance imaging diagnosis. The Zr-Cu binary alloys were prepared using the arc-melting process with zirconium strips and oxygen-free copper. This binary alloy has two dominant phases consisting of α-Zr and CuZr2 intermetallic phase. The magnetic susceptibility of the Zr-Cu binary alloys was extremely low, approximately 10−7; this level is approximately one order less than that of pure Zr and other commercialized metallic biomaterials. Consequently, Zr-Cu binary alloys have the potential to be used as biomaterials with low magnetic property.
