Phosphor bronze 6.25% wire mesh (C51980 phos bronze wire mesh) is a bronze alloy nominally comprised of 93.55% copper, 6.25% tin, and 0.2% phosphorus, with small additions of zinc (0.15%), nickel (0.125%), iron (0.125%), and lead (0.025%). The 6.25% tin helps to increase its strength and resistance to corrosion, and 0.2% phosphorus helps to increase its stiffness and wear resistance. As such, phosphor bronze is used as opposed to 90-10 commercial bronze when weaving fine bronze meshes with small wire diameters (i.e. 200 mesh .0021″ dia phos bronze). C51980 phos bronze wire mesh possesses a superior combination of strength and ductility compared to other brass (H65 brass) and bronze (90-10 commercial bronze) wire cloth materials. C51980 phos bronze is stronger than both C510 phos bronze and C519 phos bronze.
