Abstract
The invention relates to a welding material, in particular to an aluminum-silicon brazing filler metal. The aluminum-silicon brazing filler metal comprises the constituents of Al, Si, Ni, Ag, Cu and Mn. The aluminum-silicon brazing filler metal is low in melting temperature and good in wettability and flowing property, further has good plating property, machinability and decay resistance, is high in welding joint strength, good in plasticity and strong in corrosion resistance, also has excellent hot crack resistance, and is the aluminum-silicon brazing filler metal with excellent properties.
Description
Technical field
The present invention relates to a kind of welding material, especially a kind of al-si filler metal.
Background technology
Along with the development of science and technology, Aeronautics and Astronautics, automobile, electronics, daily necessities aspect with aluminium for copper, the development having promoted aluminium alloy brazing technology with aluminium for the development of steel to a great extent.Al-Si brazing filler metal has good braze ability and mother metal color consistency, plating and corrosion resistance and this brazing filler metal can carry out Metamorphism treatment, considerably increases toughness and the buckling performance of solder and weld seam, in addition with low cost, is therefore widely used.But the liquidus curve of this brazing filler metal is at about 577 DEG C, and the fusing point of general aluminium alloy is at about 600 DEG C, and too high brazing temperature easily makes mother metal grain growth, thus affects the mechanical property of joint.As the important component part of soldering tech, the development trend of domestic and international al-si filler metal mainly concentrates on improves the aspects such as solder performance by interpolation alloying element, change production technology.
Summary of the invention
The present invention is intended to solve the problem, and provides a kind of al-si filler metal, and it adds silver, copper, nickel, manganese element on the basis of simple al-si filler metal, and overcome conventional aluminium silica-based solder fusing point high, the drawback that strength of joint is low, its technical scheme adopted is as follows:
A kind of al-si filler metal, it is characterized in that, described solder comprises following composition, and each composition is followed successively by by weight percentage:
In technique scheme, described brazing filler metal melts temperature is 500 ~ 535 DEG C, belongs to aluminium soldering high temperature hard solder.
Si can reduce the fusing point of Al, improves the intensity of weld seam, and can make Metamorphism treatment due to Si, thus makes the good toughness of weld seam, and buckling performance is stronger; In addition, at the alloy in the hypoeutectic region of Al-Si binary phase diagraml, there is good mobility, wetability and corrosion resistance; Add the fusing point that Cu element can reduce Al, improve the mobility of solder, and Cu can form solid solution with Al, thus make alloy obtain solution strengthening, improve the intensity of weld seam; Ni adds the gap filling performance that membership improves solder, improves the distribution of joint welding and matrix, thus improves the shear strength of joint; Add the temperature that a small amount of Ag, Mn can reduce solder, improve spreadability, improve the intensity of solder.
Tool of the present invention has the following advantages: fusion temperature is low, wettability and good flowing properties, also have good plating, machinability, decay resistance, and strength of welded joint is high, plasticity is good, corrosion resistance is strong, also having excellent heat crack resistance, is a kind of al-si filler metal of function admirable.
