Binder Content<\/b><\/p><p class=\"p3\">The binder (Cobalt or Nickel) acts like glue that holds the hard grains together.<\/p><p class=\"p3\">Its percentage \u2014 usually between 6% and 12% \u2014 controls the balance between hardness and toughness.<\/p><ul class=\"ul1\"><li class=\"li3\"><p>Lower binder (\u22646%): High hardness, low ductility<\/p><\/li><li class=\"li3\"><p>Higher binder (10\u201312%): Better shock resistance, slightly less hardness<\/p><\/li><\/ul><p class=\"p3\">Cobalt binders are standard for general wear, while Nickel binders are preferred in corrosive environments such as chemical and marine applications.<\/p><p class=\"p4\"><b>3).<a href=\"https:\/\/www.retopz.com\/ko\/porosity-in-the-tungsten-carbide-industry-an-explanatory-overview\/\" target=\"_blank\" rel=\"noopener\"> \ub2e4\uacf5\uc131<\/a> \uadf8\ub9ac\uace0 <a href=\"https:\/\/www.retopz.com\/ko\/density-in-the-tungsten-carbide-industry-an-explanatory-overview\/\" target=\"_blank\" rel=\"noopener\">\ubc00\ub3c4<\/a><\/b><\/p><p class=\"p3\">Porosity means small air gaps left after sintering.<\/p><p class=\"p3\">Too much porosity weakens the material and allows fluid infiltration, which accelerates corrosion and erosion.<\/p><p class=\"p3\">High-quality bushings have density \u2265 14.5 g\/cm\u00b3 and are nearly pore-free.<\/p><p class=\"p3\">Suppliers measure this using ultrasonic testing and density checks, ensuring structural uniformity.<\/p><p class=\"p4\"><b>4). Binder Distribution<\/b><\/p><p class=\"p3\">Uniform binder distribution prevents weak zones or cracks during load cycles.<br \/>A poor mix can cause uneven stress concentration or localized corrosion, especially in high-pressure pumps.<\/p><p class=\"p3\">Advanced manufacturers use vacuum sintering to achieve even binder flow and better bonding between WC and metal
