Good Quality 1/4 7/8 Inch Air Conditioner Pancake Coil Copper Tube For Heat Exchanger
ASTM B188-2002 C11000 pure copper (also known as red copper) generally has good electrical and thermal conductivity, corrosion resistance and machining properties, can be welded and brazed. Containing reduced electrical and thermal conductivity impurities less, trace oxygen has little effect on electrical and thermal conductivity and processing properties, but easy to cause "hydrogen disease", not in high temperature (such as >370℃) reducing atmosphere processing (annealing, welding, etc.) and use. Pure copper generally refers to a purity higher than 99.3% of industrial metal copper. C11000 has excellent cold and hot working performance. Mainly used as building materials, automobile radiator, gasket, radio parts.
ASTM B75-2002(2010) is the American standard "Seamless copper pipe standard specification", C12200 belongs to the standard phosphor deoxidation bronze number. This material has good welding performance and cold bending performance, generally no "hydrogen disease" tendency, can be processed and used in reducing atmosphere, but should not be processed and used in oxidizing atmosphere. Mainly to pipe applications, can also plate, tape or rod, wire supply. Used as gasoline or gas delivery pipe, drain pipe, condensate pipe, mine pipe, condenser, evaporator, heat exchanger, train box parts.
