The fluxes best suited for brazing copper and copper alloy tube should meet AWS Standard A5.31, Type FB3 A or FB3 C. Figure 14.7 illustrates the need for brazing flux with different types of copper and copper alloy tube, fittings and filler metals when brazing.
Copper absorption declines considerably when the function of the reticulorumen develops. The microbial metabolism of inorganic and organic sulphur compounds in the rumen results in the production of sulphide and, when additionally molybdenum is present, also in the production of thiomolybdates, which bind copper with a high affinity.
Farmers Copper offers C10100 OFE and C10200 OFHC copper sheet and plate in thicknesses up to 3thick .C101 copper is 99.99% pure, and C102 copper is 99.95% pure, contain essentially no oxygen. Both Copper alloy 101 and alloy 102 has high electrical and thermal conductivity and very high resistance to hydrogen embrittlement.
