Abstract
The present invention relates to an aluminium alloy formula for a heat finish forge connecting rod. The heat finish forge connecting rod is mainly prepared from the components with the following proportion by weight in the alloy formula: 0.6 to 1.2 of Si, 0.1 to 0.7 of Fe, 3.9 to 4.8 of Cu, 0.4 to 1 of Mn, 0.4 to 0.8 of Mg, 0.01 to 0.3 of Zn, 0.01 to 0.15 of Ti, 0.8 to 1.5 of Re, 89.5 to 93.6 of Al and impurities as the rest. The aluminium alloy formula is characterized in that the formula has a rare earth element Re which is powder rare earth. Aluminium alloy made by the formula has the advantages of fine crystal grains, good technology fluidity, low content of the Si, high plasticity, material saving and low cost, and the aluminium alloy formula can carry out heat finish forge molding. An engine connecting rod made by the alloy has the advantages of good wear resistance and corrosion resistance, high intensity and hardness and long service life.
Description
Technical field
The utility model relates to a kind of prescription of aluminium alloy and forms, especially for the aluminium alloy formula of making thermal fine-forged lever.
Background technology
Connecting rod is the main movement parts of reciprocating compressor, petrol motor, diesel engine, connects bent axle and wrist pin, bears during work to stretch and compression, and its quality quality directly influences the use properties and the life-span of complete machine.Generally between 8～13%, material plasticity is poor for existing aluminum alloy connecting rod, Si content, can not forge, and is wear-resisting, corrosion resisting property is poor; Contain expensive nickel in the composition, and waste material is more during casting, causes that cost raises.As reduce Si content, the requirement that does not then reach intensity and hardness again.
Summary of the invention
Thereby the purpose of this utility model is to overcome existing aluminum alloy connecting rod produces poor performance, defect of high cost because the problem in the alloy formula causes connecting rod not forge, provide that a kind of product is wear-resisting, solidity to corrosion good, intensity and hardness improves, and the low thermal fine-forged lever aluminium alloy formula of cost.
The technical solution of the utility model is: the main body composition of thermal fine-forged lever aluminium alloy formula is Al, contain Si, Fe, Cu, Mn, Mg, Zn, Ti element, improvements are to contain rare earth element Re in the prescription, and the weight percent of each composition in alloy formula is: Si 0.6～1.2; Fe0.1～0.7; Cu 3.9～4.8; Mn 0.4～1.0; Mg 0.4～0.8; Zn 0.01～0.3; Ti0.01～0.15; Re 0.8～1.5; Al 89.5～93.6; Impurity 0.05～0.1.More than each composition total amount sum be 100%.
Above-mentioned rare earth element is the powder rare earth.
Adopt technique scheme, in aluminium alloy, add 0.8～1.5% rare earth element, make the alloy grain refinement, improve process flowability, replace expensive nickel, reduce the content of Si greatly, increase plasticity, can carry out hot finish forge moulding, save material, reduce cost.Add rare earth element and also can reduce thermal expansivity, reduce internal stress, improve the corrosion resisting property of product.The connecting rod that adopts alloy formula of the present invention to make, after testing, its tensile strength can reach 465～471Mpa, and hardness all is higher than currently available products greater than 115HBS.
Embodiment
Taking by weighing each composition gross weight as following weight percent is 500Kg, and Si 1.0; Fe 0.5; Cu 4.2; Mn 0.6; Mg 0.5; Zn 0.1; Ti 0.05; Re 1.2; Al 91.8; Other has impurity 0.05, after the mixing, melts, pours into aluminium alloy, and in special metal pattern, the petrol motor connecting rod is made in hot finish forge moulding.
Claims (2)
1, a kind of thermal fine-forged lever aluminium alloy formula, the main body composition is Al, contains Si, Fe, Cu, Mn, Mg, Zn, Ti element, it is characterized in that containing rare earth element Re in the prescription, the weight percent of each composition in alloy formula is: Si 0.6～1.2; Fe 0.1～0.7; Cu 3.9～4.8; Mn 0.4～1; Mg 0.4～0.8; Zn 0.01～0.3; Ti0.01～0.15; Re 0.8～1.5; Al 89.5～93.6; Impurity 0.05～0.1; More than each composition total amount sum be 100%.
2, by the described thermal fine-forged lever aluminium alloy formula of claim 1, it is characterized in that described rare earth element is the powder rare earth.
