95WNIFE tungsten alloy bucking bar price which density is 18.0g/cm3 is 165.00USD/PC on Apr. 16, 2019. Bucking bars are created with tungsten heavy alloys that have two-phase composites consisting of W-Ni- Fe or W-Ni- Cu or even W-Ni-Cu-Fe, some tungsten alloy also contain Co、Mo、Cr, etc. They have very high melting point and have a density twice that of steel and are more than 50% heavier than lead. Tungsten content in conventional heavy alloys varies from 90% to 97% .This high tungsten phase content is the reason for their high density.
