Brass tube and red copper tube is copper alloy difference: brass tube is copper zinc alloy, and red copper tube is not alloy, is pure copper.
Brass tube and copper tube chemical composition difference: brass tube copper content is not high copper tube, copper tube copper content is very high. Brass tube and copper tube chemical composition in the specific content is also different.
Brass tube and copper tube appearance color difference: brass tube appearance color is golden, and copper tube appearance color is purplish red.
Brass tube and copper tube price difference: the same specifications of brass and copper tube, or copper tube price is high, which is related to the copper content.
Brass tube and copper tube thermal conductivity difference: copper tube thermal conductivity of 338 kcal/m · h · C, than yellow tube thermal conductivity of 80 kcal/m · h · C to much higher.
Brass tube and copper tube ductility difference: copper tube ductility is much better than brass ductility.
Brass tube and copper tube corrosion resistance difference: copper tube in the long-term Cl containing environment than brass tube rust longer.
Brass tube and copper tube cutting performance difference: brass tube and copper tube cutting performance or brass mind a bit.
Brass tube and copper tube density difference: copper tube density than brass tube.
Brass tube and copper tube strength difference: brass tube strength is stronger than copper tube.
Performance of thermal conductivity of copper 338 kcal/m C, more than 80 kcal heat conduction performance of brass/m C is much higher, and the ductility of copper can also ductility can much better than brass. Therefore, good air conditioning copper tube to make.
