The process by which brass rods are made

All elements without exception reduce the electrical and thermal conductivity of the brass rod. If the element is dissolved in brass, the internal lattice constants change, wave propagation occurs when the free charge is fixed, and fluidity increases resistance. Brass, in contrast, neither the molecular concentration in solid, there isn't much temper elements on brass and the conductivity of the heat transfer effect is very little, especially should pay attention to some elements in solid brass quality molar concentration with temperature decrease and reduce, violently with hydroxide precipitation and metal compounds, as well as tempering heat treatment and strengthening the brass alloy, And the conductivity reduction is very little, which is the key to the scientific research of high strength and high conductivity aluminum alloy, fine grain strengthening standard, here should be especially emphasized is iron, silicon, wrong, chromium and brass aluminum alloy is very important high strength and high conductivity aluminum alloy; Because the influence of aluminum alloy elements on the characteristics of brass is cumulative, CoCr -- Zr aluminum alloy is well-known for its high strength and high conductivity aluminum alloy.

The mechanism of copper base corrosion resistant aluminum alloy should be single phase electricity to prevent the second phase in the aluminum alloy from electrochemical reaction. Therefore, aluminum alloy element should have a very large molar concentration of solid mass on brass, and even the element of endless phase dissolution. Single-phase electric brass bar, green brass bar and white brass bar used in engineering projects have high quality corrosion resistance, which is the key raw material of heat exchanger.

There are soft phase and hard phase in the mechanism of copper base wear resistant aluminum alloy, so when the fine grain is strengthened, it is necessary to ensure that the element added in addition to solid dissolve brass bar, there should also be hard phase precipitation, the typical hard phase in brass aluminum alloy Ni3Si, FeALSi chemical substances. In recent years, the aluminum alloy of automotive synchronizer transmission gear developed and designed is soft phase a, and the negative phase is hard phase. The A phase is not suitable for more than 10%.

Solid copper rod aluminum alloy with polycrystalline changes has vibration reduction characteristics, such as Cu - Mn aluminum alloy, solid underneath the thermal ductility of the austenite change process of aluminum alloy has memory characteristics, such as Cu - Zn - Al, Cu - Al - Mn aluminum alloy.

The color of brass rod can be changed according to the method of aluminum alloy element, such as zinc, aluminum, tin, nickel and other elements, with the transformation of the composition, the color also produces a red, blue, yellow and white transformation, effectively manipulate the composition will get imitation gold raw materials and imitation silver aluminum alloy.

The elements choosed for brass and aluminum alloy thin crystal substrates must be common, inexpensive and environmentally friendly. Adding elements must be based on diversity and a small number of criteria. Aluminum alloy raw materials can be used for development. Aluminum alloy should be high quality, suitable for processing into a variety of products and semi-finished products.
