High-precision brass bar manufacturing principles
(1) all elements without exception, to reduce the electrical conductivity and thermal conductivity of the copper rod, where the elements in solid solution of copper rod, resulting in the lattice distortion of the copper rod, so that the directional flow of free electrons generated when the wave scattering, so that resistance The rate of increase in the contrary there is no solid solubility or very little solid solution elements in the copper rod, the electrical and thermal conductivity of the copper rod should be noted that some elements in the copper rod in the solution as the temperature decreased heated to reduce the precipitation of elemental and metal compounds, both solid solution and dispersion strengthened copper rod alloys, but also the electrical conductivity decreased much. for high strength and high conductivity alloy is an important alloying principle here should be particularly noted that the alloy composed of four elements iron, silicon, wrong, chromium and copper rod is extremely important and high-strength high conductivity alloy; of alloying elements on the copper rod performance is superimposed on the CoCr-Zr alloy is a well-known high strength and high Lead alloys;
(2) copper-based corrosion resistant alloy of the organization should be single-phase, to avoid the second phase caused by electrochemical corrosion in the alloy. This added to the alloying elements in copper rod should have a lot of solid solubility, or even unlimited mutual solubility of elements in the engineering applications of single-phase brass rods, bronze rods, white copper rod has excellent corrosion resistance , is an important heat exchange materials.
(3) wear-resistant copper-based alloys are soft phase and hard phase, and therefore must ensure that the people in the alloying elements in addition to solid solution of copper rod should also be hard phase precipitates, copper rod alloys The typical hard the Ni3Si, FeALSi, compounds. Developed in recent years, the auto synchronizer gear alloy in a phase of the soft phase, negative phase of the hard phase, a phase of not more than 10%.
(4) the damping properties of solid-state multi-crystalline transition of the copper rod alloys such as Cu-Mn alloy, solid state thermo-elastic martensitic transformation process of the alloy with memory performance, such as the one of Al in Cu Zn, Cu, Al a Mn alloy.
(5) the color of the copper rod to change the way of the addition of alloying elements, such as the increase of people of zinc, aluminum, tin, nickel and other elements, as the content changes, the color red Hitodo one yellow and one white changes, reasonable to control the content of imitation gold materials and imitation silver alloy.
(6) the elements selected by the alloying of copper rod and alloy is commonly used, inexpensive and pollution-free, the added element should be in line with the diverse small amount of the principle of alloy raw materials to comprehensive utilization of the alloy with excellent process performance, fitness processed into a variety of finished and semi-finished products.
