Three　types　of　Ni8W/Ni12W/Ni8W　composite　substrates　with　different　layer　thickness　ratios　are　thoroughly　investigated.　A　composite　substrate　with　a　1:2:1　thickness　ratio　is　found　to　be　more　appropriate　for　application　because　of　its　sharper　cube　texture,　better　mechanical　strength,　and　lower　magnetization.　To　overcome　cracking　and　fracture　during　cold　rolling,　hot　rolling　is　sometimes　conducted　before　cold　rolling.　A　second　step　in　the　annealing　process　is　researched　comprehensively　to　fabricate　a　121-composite　substrate　with　a　sharper　cube　texture.　A　nearly　non-ferromagnetic　121-Ni8W/Ni12W/Ni8W　composite　substrate　with　a　sharp　cube　texture　and　strong　mechanical　strength　is　successfully　fabricated.
