CDA 102 Copper Wire Mesh – Alloy Overview
CDA 102 copper wire mesh (aka C10200 copper wire mesh) is the most extensively used copper alloy in the industrial wire cloth world. Where no specific copper type is specified, it is assumed CDA 102 copper wire cloth is acceptable. C10200 copper is a pure, oxygen-free copper with a minimum copper content of 99.95% and a maximum oxygen content of 0.001%. As with other pure, oxygen-free coppers, CDA 102 copper wire mesh possesses excellent electrical and thermal conductivity, and is very malleable, pliable, and ductile. In comparison to bronzes and brasses, C10200 copper wire cloth possesses lesser abrasion resistance, hardness and tensile strength.
Following weaving, CDA 102 copper wire cloth is reddish-brown in color. Over time, the surface will slowly patina to a greenish/blue color known as verdigris. The environment plays a primary factor in the pace at which C10200 copper wire mesh will patina. In dry conditions, it can take years for the patina to take full effect, whereas in outdoor, seaside settings, CDA 102 copper wire cloth will fully patina in as little as six months.
If desired, you can speed up the patina effect by removing surface oil with a mild household cleaner, or can slow down the patina effect by applying a lacquer, wax, or occasional oiling to protect the C10200 copper wire cloth from the environment.
Some characteristics of CDA 102 copper wire cloth which dictate its wide use are:
- The most widely used copper alloy for wire cloth.
- Non-magnetic in all forms.
- Reddish-brown in color following weaving; will slowly patina to a greenish/blue color known as verdigris.
- Withstands outdoor exposure without rusting.
- Superior resistance to atmospheric corrosion vs. bronze & brass alloys.
- Corrodes when exposed to ammonia and other salts.
- Excellent thermal and electrical conductivity.
- Can be cut, formed, and welded.
Industries & Applications
Given its mechanical, thermal, and electrical properties, CDA 102 copper wire cloth is principally used in Faraday cages, RFI shielding, HVAC units, and other electrical applications. Due to its unique patina color, CDA 102 copper wire mesh is frequently used by architects, artists, designers, and homeowners in both decorative and functional settings. Additional industries and applications which commonly use C10200 copper wire cloth include:
