Principle Of Brass Rod Manufacturing

(1) All elements reduce the electrical conductivity and thermal conductivity of the copper rod without exception. Any element is dissolved in the copper rod, causing the lattice distortion of the copper rod, causing wave scattering when the free electrons are directed to flow, so that the resistance The rate increases, on the contrary, there is no solid solubility or little solid solution in the copper rod, which has little effect on the conduction and heat conduction of the copper rod. In particular, it should be noted that the solid solubility of some elements in the copper rod decreases with temperature. It is drastically reduced, and the precipitation of elemental and metal compounds can not only solidify and disperse the strengthened copper rod alloy, but also reduce the electrical conductivity. This is an important alloying principle for the study of high-strength and high-conductivity alloys. It is pointed out that the alloy consisting of four elements of iron, silicon, silicon and chrome and copper rod is an extremely important high-strength and high-conductivity alloy; since the influence of alloying elements on the performance of copper rods is superimposed, the CoCr-Zr-based alloy is a high-strength and high-duct alloy. ;

(2) The structure of the copper-based corrosion-resistant alloy should be single-phase, avoiding the occurrence of electrochemical corrosion caused by the presence of the second phase in the alloy. For this reason, the added alloying elements should have a large solid solubility in the copper rods, even the mutually soluble elements, and have excellent corrosion resistance in single-phase brass rods, bronze rods and white copper rods for engineering applications. It is an important heat exchange material.
