Abstract
The invention discloses a kind of nontoxic solder without copper, the solder is made up of the component of following mass percent：Sn2% 5%, Fe0.3% 1.2%, In1%, Si 0.15% 0.35%, Al surpluses；This kind of nontoxic solder without copper, by adding after Fe, Si element, improves its fusing point, improves the hardness of alloy；As the electric conductivity of Fe increase solder alloy is consequently increased；Primary raw material Sn, In, Al of the present invention rich content, contents of the particularly Al in the earth's crust occupy the 3rd, while the ductility of the increased alloy of addition of Sn, In, Al material.
Description
【Technical field】
The present invention relates to a kind of solder, more particularly to a kind of nontoxic solder without copper.
【Background technology】
The fusion temperature of melting welding is usually less than the solidus of mother metal, and its chemical composition, mechanics, thermal characteristic are all and female
Material relatively, such as various welding rods, flux-cored wire.Weld strength is often not less than mother metal in itself；And the fusion temperature of solder must
The solidus of mother metal must be less than, its chemical composition is often mutually gone farther out with mother metal, and brazed seam is very thin, precision size, but Joint intensity is more
Not as good as mother metal in itself, corrosion stability is also poor for number.Current people solder have been carried out substantial amounts of research, but now most
Solder all has that fusing point height, poor ductility, cost are high, the problem of with the addition of poisonous material and all add copper substantially, needs now
Want that a kind of fusing point is low, ductility is good, cost is low, the nontoxic solder without copper replaces existing solder.
【The content of the invention】
It is a primary object of the present invention to provide a kind of nontoxic solder without copper, asking in background technology can be effectively solved
Topic.
To achieve the above object, the technical scheme taken of the present invention is：A kind of nontoxic solder without copper, the solder be by with
The component composition of lower mass percent：
Preferably, the solder constituting by following mass percent：
Compared with prior art, the present invention has the advantages that：This kind of nontoxic solder without copper, by add Fe,
After Si elements, its fusing point is improved, the hardness of alloy is improved；Electric conductivity with Fe increase solder alloy also increases therewith
Plus；Primary raw material Sn, In, Al of the present invention rich content, contents of the particularly Al in the earth's crust occupy the 3rd, simultaneously
The ductility of the increased alloy of addition of Sn, In, Al material.
【Embodiment】
To be easy to understand the technical means, the inventive features, the objects and the advantages of the present invention, with reference to
Embodiment, is expanded on further the present invention.
A kind of nontoxic solder without copper, the solder is made up of the component of following mass percent：
Preferably, the solder constituting by following mass percent：
Advantages of the present invention：The fusing point of solder is relatively low, and production cost is low, and electric conductivity is good.
The general principle and principal character and advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the simply explanation described in above-described embodiment and specification is originally
The principle of invention, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
Claims (2)
