Phosphor Bronze 5% A Wire Mesh – Alloy Overview

Phosphor bronze 5% A wire mesh (aka C510 phos bronze wire mesh) is a bronze alloy nominally comprised of 94.8% copper, 5% tin, and 0.2% phosphorus, with small additions of zinc (0.15%), iron (0.05%), and lead (0.025%). The 5% 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). C510 phos bronze wire mesh possesses a superior combination of strength and ductility compared to other brass (i.e. 65-35 yellow brass) and bronze (i.e. 90-10 commercial bronze) wire cloth materials. When compared to C519 phos bronze and C51980 phos bronze, C510 phos bronze is a weaker material. Some characteristics of phosphor bronze 5% A wire cloth which dictate its use are:

  • Infrequently used phosphor bronze alloy for wire cloth (C519 phos bronze being the most used).
  • Weaker than other phos bronze alloys.
  • Superior strength and ductility vs. brass and commercial bronze alloys.
  • Non-magnetic in all forms.
  • Rich bronze (i.e. brown-red) in color.
  • Withstands outdoor exposure without rusting.
  • Good thermal and electrical conductivity.
  • Antimicrobial.
  • Can be cut, formed, and welded.
