Abstract
The invention discloses a lead-tin alloy material with good fluidity. The lead-tin alloy material comprises 10-20% of antimony, 8-9% of copper, 40-50% of lead, 10-20% of tin, 8-12% of nickel, 8-11% of beryllium and 1.1-1.3% of other few impurities. Thus, the lead-tin alloy material with good fluidity has the effects of stable performance, low melting point, good fluidity and small contractility.
Description
Technical field
The present invention relates to a kind of terne metal, be specifically related to a kind of terne metal material of good fluidity.
Background technology
Terne metal is a most widely used class non-ferrous metal structured material in the industry, in Aeronautics and Astronautics, automobile, machinofacture, boats and ships and chemical industry, widely apply, along with the develop rapidly of science and technology and industrial economy in recent years, demand to the terne metal welding structural element is increasing, makes the Research on Weldability of terne metal also thereupon deeply.The widespread use of terne metal has promoted the terne metal Development of Welding Technology, and Development of Welding Technology has been expanded the Application Areas of terne metal again simultaneously, so the welding technique of terne metal is just becoming one of focus of research.
By national standard, Babbitt metal can be divided into two kinds of tin-based alloy and lead 2-base alloys.The intensity of lead 2-base alloy and hardness ratio tin-based alloy are low, and solidity to corrosion is also poor.So the client selects tin-based alloy for use usually when using Babbitt metal, its trade mark commonly used has ZChSnSb11-6, ZChSnSb8-4, ZChSnSb8-8 etc.Although the performance of lead 2-base alloy does not have tin-based alloy good, there are many clients still to select to use, both economical because it uses, its trade mark commonly used has ZChPbSb16-16-2, ZChPbSb1-16-1 etc.Babbitt metal (comprising tinhase bearing metals and graphite metal) is the bearing materials that is widely known by the people most, has tinbase and the graphite metal of antifriction characteristic.Gained the name by the invention of American's Babbitt, because it is white in color, claim white metal again, its application can be traced back to the Industrial Revolution epoch.Tin-base babbit and lead-base babbitt with antifriction characteristic are unique materials that is fit to respect to the rotation of soft axle, compare with other bearing materials, have better adaptability and embedability, be widely used in big marine diesel engine, turbine, alternator, and other mining machinery and large rotating machinery etc.
Summary of the invention
The object of the present invention is to provide to have stable performance, fusing point is low, good fluidity, the terne metal material of a kind of good fluidity of the little effect of shrinkability.
Technical scheme of the present invention is: a kind of terne metal material of good fluidity, the terne metal material of described good fluidity comprises elements such as antimony, copper, lead, tin, nickel, beryllium and other small amount of impurities, each element wt proportioning is that antimony accounts for 10%-20%, copper accounts for 8%-9%, lead accounts for 40%-50%, and tin accounts for 5%-15%, and nickel accounts for 8%-12%, beryllium accounts for 8%-11%, and other small amount of impurities account for 1.1%-1.3%.
In a preferred embodiment of the present invention, described small amount of impurities comprises hydrogen and mercury.
In a preferred embodiment of the present invention, each composition weight proportion of the terne metal material of described good fluidity is that antimony accounts for 12%, and copper accounts for 8%, and lead accounts for 44%, and tin accounts for 13%, and nickel accounts for 11%, and beryllium accounts for 10.8%, and other small amount of impurities account for 1.2%.
The terne metal material of a kind of good fluidity of the present invention has stable performance, and fusing point is low, good fluidity, the effect that shrinkability is little.
Embodiment
Below in conjunction with preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
In one embodiment, a kind of terne metal material of good fluidity, the terne metal material of described good fluidity comprises elements such as antimony, copper, lead, tin, nickel, beryllium and other small amount of impurities, and each element wt proportioning is that antimony accounts for 10%-20%, and copper accounts for 8%-9%, lead accounts for 40%-50%, tin accounts for 5%-15%, and nickel accounts for 8%-12%, and beryllium accounts for 8%-11%, other small amount of impurities account for 1.1%-1.3%, and described small amount of impurities comprises hydrogen and mercury.
Further specify, each composition weight proportion of the terne metal material of described good fluidity is that antimony accounts for 12%, and copper accounts for 8%, and lead accounts for 44%, and tin accounts for 13%, and nickel accounts for 11%, and beryllium accounts for 10.8%, and other small amount of impurities account for 1.2%.
Can debug according to different ratios according to different demands, thereby reach different results of use.Antimony, intensity and the hardness of copper in order to improve alloy in the terne metal.Its frictional coefficient is little, and good toughness, thermal conductivity and solidity to corrosion are arranged, mainly in order to make sliding surface bearing.Based on tinsel, the tinsolder that has also contains a spot of antimony.Leaded 38.1% tin alloy is commonly called as scolding tin, and about 183 ℃ of fusing point is used for the welding of electrical instrumentation industry element, and the sealing of automobile radiators, heat exchanger, food and drink container etc.Utilize the etch resistant properties of tin alloy, it is coated on various electrical elements surface, both had protectiveness, have ornamental again.It is commonly used that the plumbous system of tin, tin nickel are arranged is coating etc.Terne metal (comprises terne metal, lead-free tin alloy) can be used for manufacturing various exquisite alloy ornament, alloy handicraft, as ring, necklace, bracelet, earrings, brooch, button, tie pin, scrambled eggs, technology pendulum decorations, alloy photo frame, religion emblem will, miniature statue, souvenir etc.Terne metal can produce codeposition under very low current density.Pb-sn alloy plating is lower than lead-coat and the tin coating porosity of same thickness., its welding property is considerably beyond pure tin coating.Therefore, obtained using widely at aerospace, electronic enterprises. stable performance, fusing point is low, good fluidity, shrinkability is little.The crystal grain children is thin, and toughness is good, and soft or hard is suitable, smooth surface, and no sand hole, no fault, flawless, polishing and electroplating effect are good.The invention provides a kind of terne metal material of good fluidity, have stable performance, fusing point is low, good fluidity, the effect that shrinkability is little.
The specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the disclosed technical scope of the present invention, and variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
