90-10 Commercial Bronze Wire Mesh – Alloy Overview
90-10 commercial bronze wire mesh (aka C220 bronze wire mesh) is the most extensively used bronze alloy in the industrial wire cloth world. As its common industry name suggests, 90-10 commercial bronze is comprised of 90% copper and 10% zinc, with small additions of lead (0.025%) and iron (0.025%). When compared to copper wire cloth, C220 bonze wire cloth possesses much better abrasion resistance, hardness, and tensile strength; it also exhibits improved corrosion resistance and lower electrical conductivity. As a higher zinc content results in a stronger, more ductile material, 90-10 commercial bronze is weaker and less ductile than other brass wire cloth alloys (i.e. 65-35 yellow brass). In comparison to phosphor bronzes, C220 bronze is a softer material. Some characteristics of 90-10 commercial bronze wire cloth which dictate its wide use are:
- The most widely used bronze alloy for wire cloth.
- Non-magnetic in all forms.
- Rich bronze (i.e. brown-red) in color.
- Withstands outdoor exposure without rusting.
- Superior resistance to atmospheric corrosion vs. brass alloys.
- Corrodes when exposed to ammonia and other salts.
- Good thermal and electrical conductivity.
- Can be cut, formed, and welded.
Industries & Applications
90-10 commercial bronze wire cloth is principally used in liquid filtration and particle separation, insect screen, and architectural applications. Additional industries and applications which commonly use C220 bronze wire cloth include:
