Bulk metallic glass (BMG) has different mechanical, electrical, magnetic, chemical and physical properties from the general polycrystalline alloy because the internal arrangement of atoms is random. Thus, BMG has well mechanical strength, high hardness, wear resistance, corrosion resistance, and good surface smoothness. Based on these features, BMG has a very promising future in the industry. In this study, a copper mold casting method is used to prepare Cu45Zr45Al5Ag5 BMG. The casting process is followed by giving -25 o C ambient temperature with machine cooling. The sample with rod-shape, sizes around 2 to 4 mm in diameter and 30 mm in length was successfully produced through copper mold casting method. The rod then sliced into disk-shaped specimens. The BMG sample is validated using Scanning Electron Microscopy (SEM), Energy Dispersion Spectrometer (EDS), Differential Scanning Calorimetry (DSC), Electron Probe X-ray Micro Analyzer (EPMA), and X-ray Diffraction (XRD).
