C10100 - Oxygen-Free Electronic Grade Copper is the highest grade of copper at 99.99% purity.
C10200 - Oxygen-Free High Conductivity Copper is produced by melting and pouring Copper in the presence of carbon or carbonaceous gases, so that no oxygen can be absorbed. No deoxidizing agent is required. It combines most of the advantages of ETP and Deoxidized Copper. It is excellent for deep drawing, has a high electrical and thermal conductivity, and resists the embrittling effect of reducing gases (hydrogen) on equipment operated at elevated temperatures, although it is not as suitable for welding as Deoxidized Copper. This type of copper is specially good for severe deep drawing, spinning, and close radius bending, and is used in electronic tubes or similar applications because it makes a perfect seal to glass. For electrical uses requiring conductivity higher that Deoxidized Copper affords, Oxygen-Free Copper is usually specified.
C11000 - Electrolytic Tough Pitch Copper has long been the standard type of commercial wrought copper used for the production of wire, rod, plate, sheet and strip. The presence of very small amounts of oxygen affects some of the mechanical properties to a measurable extent, but this grade of copper is entirely satisfactory for most of the usual processes. It is easy to deep draw, spin, or stamp. It is the logical choice for bus connections, switch and panel boards, circuit breakers, and power feed systems in general, because of high electrical conductivity, ease of soft or silver soldering and ability to receive a silver plate. Expansion joints, kettles, vats, pressure vessels, distillery and other process equipment are readily formed from the metal. Its resistance to corrosion assures a long life. For welding and high temperature applications see Deoxidized Copper and Oxygen Free Copper.
C12200 - Deoxidized Copper is produced by introducing phosphorus or another element as a deoxidizing agent to assure the removal of all oxygen. This type differs from ETP Copper in that it has lower electrical and thermal conductivity, but it forms and bends more readily in difficult applications. It is particularly suitable for applications requiring hot working, annealing soldering, brazing or welding, operations in which the residual phosphorus prevents the absorption of oxygen by the copper. If copper sheets or plates are to be welded, this type of copper is preferred because of its resistance to embrittlement by reducing gases, such as hydrogen, at high temperatures. Deoxidized Copper is widely used for pipe and tube for plumbing, gas and oil lines, refrigeration, condensers, pulp and paper lines, brewery and distillery tubes, brew kettles, vats and industrial tanks.
Construction (Roofing) Copper - Any copper with a minimum copper content of 99.5% to be used in building construction. Copper has been valued for centuries as a roofing material, for its aesthetically pleasing green patina that forms over time. It is also very economical, as many copper roofs have lasted up to 100 years and it is 100% recyclable. The roofing copper specification, ASTM B370 allows a slightly broader chemistry than does ASTM B152. Copper sheet 10 oz through 48 oz in our inventory is referred to as roofing copper.
