Composition and technological properties of silicon bronze
A unique class of brasses in which silicon is the key element of aluminum alloys. In addition to silicon, manganese, nickel, zinc and other elements are added. Silicon bronze has good physical properties, corrosion resistance, wear resistance and electric weldability. It is very easy to produce and process. It has no magnetic band, does not cause fire when impact, and does not lose its original characteristics of raw materials at ultra-low temperature. Common models are QSi3-1, QSi1-3 and so on.
Phosphor bronze plate is a better kind of alloy copper, has excellent electrical conductivity, not easy to burn, ensure the performance at the same time has strong fatigue resistance. Phosphor bronze is commonly used as anti-wear parts and spring shock absorbers, such as computer connectors, mobile phone connectors, new end technology connectors, electronic and electrical torsion springs, switches, slots for electronic equipment, keys, electrical connectors, flexible circuit boards, vibration plates and terminals.
The technical process of preparation of tungsten-copper alloy by powder metallurgy is made by mixing of powder ingredients and limited forming and sintering. Tungsten-copper or molybdenum-copper powder was sintered in liquid phase at 13001500° after limited molding.
The molten steel alloy of casting copper alloy is easy to be oxidized in the liquid state, and the formed oxide is dissolved in copper and the mechanical properties of the alloy are reduced. The same as aluminum alloy, copper alloy is generally melted by crucible furnace, so that copper liquid does not directly contact with fuel and air, in order to reduce the oxidation and loss of metal, to maintain the purity of metal. In order to prevent copper oxidation, molten bronze should be added glass, borax and other flux to cover the copper liquid. Because the zinc in brass itself is a good deoxidizer, so when melting brass, do not need to add another flux and deoxidizer.
Copper bar insulation can prevent breakdown of the high-pressure system in the equipment room, increase the ground potential, and damage electronic components. So copper bar insulation is to be done, then what are the copper bar insulation processes?
As a kind of alloy material widely used in the current market, phosphorus copper plate is used in many industries. However, in reality, some friends in the first contact with this kind of material, the advantages and disadvantages of it are not very understanding. Here is a look at the specific advantages and disadvantages of the discrimination method.
