Red copper bar manufacturing needs to follow the process requirements

 As a widely used metal material, red copper bar is not strange to many customers. In fact, this material also needs to follow some technological requirements when it is manufactured. Let's learn about it.

The personage inside course of study says, all elements are invariably reduce the electrical conductivity and thermal conductivity of copper bar, every element is dissolved in copper rod, copper bar caused by lattice distortion, the free electrons generated when the directional flow wave scattering, and increase resistivity, on the contrary, the red copper bar is little or no solid solubility of solid solution elements, very little effect on copper conductive and heat conduction, In particular, it should be noted that the solid solubility of some metals in the copper bar decreases sharply with the decrease of temperature, and the precipitation of elemental and metal compounds can not only strengthen the solid solution and dispersion of the copper bar alloy, but also reduce the electrical conductivity.

Copper base corrosion resistant alloy in single-phase, organizations should be avoided in a second phase caused electrochemical corrosion of metal, maintain, and join the alloying element in copper bar should be have a lot of solid solubility, even infinite mutually soluble elements, in the engineering application of single-phase red copper, bronze sheet, white copper plate has excellent corrosion resistance, is an important heat transfer materials.

It is important to note that the red copper in the copper base alloy organization are very soft and hard phase, therefore, must ensure that when alloying elements in addition to solid soluble in copper bar, joined by separating should also have a hard, typical of the hard phase in the copper alloy with ni3si, fealsi compounds, etc., in recent years, a phase in the development of automobile synchronizer gear alloy as soft phase, Negative phase is hard phase, a phase should not be more than 10%.
