The　improvement　of　mechanical　and　magnetic　properties　of　textured　NiW　alloy　tapes　is　considered　as　a　main　challenge　for　RABiTS　substrates　in　coated　conductors.　The　present　paper　summaries　the　successful　development　of　several　textured　NiW　substrate　tapes　with　high　W　contents　as　well　as　advanced　NiW　composite　substrates　with　high　strength　and　reduced　magnetization　in　our　previous　works.　The　fabrication　process　of　these　tapes　and　their　characterizations　are　presented　in　detail.　The　results　on　the　texture　quality　and　mechanical　properties　as　well　as　on　the　magnetic　behaviour　of　these　tapes　are　promising　in　view　of　the　future　application　in　coated　conductor　and　constitute　an　alternative　to　the　well　known　Ni5W　alloy　substrates.
