Abstract
The utility model relates to a three element combined dumet wire material which is provided with a copper cladding layer and a core material in a shape of a round bar, wherein the core material is cladded in the copper cladding layer. The utility model is characterized in that the core material in the shape of the round bar is composed of a steel core in the shape of the round bar and a low-expansion alloy layer which wraps the steel core in the shape of the round bar; the low-expansion alloy layer tightly contacts the inner wall of the copper cladding layer. Since the core material of the dumet wire material of the utility model is composed of the steel core in the shape of the round bar and the low-expansion alloy layer which wraps the steel core in the shape of the round bar, namely, the steel core in the shape of the round bar, the low-expansion alloy layer and the copper cladding layer jointly form the dumet wire material, thereby, the dumet wire material has the advantage of convenient radial and axial expansion coefficient adjustment.
Description
Technical field
The utility model relates to a kind of wire rod, especially a kind of Dumet wire wire rod.
Background technology
The Dumet wire wire rod is the material of semiconductor device, vacuum electron device (as electron tube, picture tube) and electric light source filament lead wire, because it is positioned at the sealing-in position of semiconductor device, vacuum electron device and electric light source in use, this just requires its radial expansion coefficient and soft (lead) glass at axial expansion coefficient and above-mentioned sealing-in position unanimous on the whole, otherwise will cause the gas leakage of sealing-in position or burst.Existing Dumet wire wire rod generally is to be made of round strip core material and copper-clad coating that this state core is coated.The axial expansion coefficient of its axial expansion coefficient and soft (lead) glass has big gap, has influenced the serviceability of product, and the core of existing Dumet wire wire rod adopts expensive iron-nickel alloy to make simultaneously, is unfavorable for reducing the production cost.Because the defective that existing Dumet wire wire rod exists is so need improve.
The utility model content
The purpose of this utility model is that the structure of existing Dumet wire wire rod is improved, and the triple combination Dumet wire wire rod that a kind of properties of product are better, cost of manufacture is lower is provided.
Dumet wire wire rod of the present utility model has copper-clad coating and the round strip core material that is coated within this copper-clad coating, it is characterized in that described round strip core material is made of with the low-expansion alloy layer that is wrapped on this circle strip steel core circle strip steel core, described low-expansion alloy layer closely contacts with the inwall of copper-clad coating.
In the utility model,, can allow above-mentioned low-expansion alloy layer fix and be wrapped in hot melting way on the round strip steel core usually in order to allow the low-expansion alloy layer closely link to each other with circle strip steel core.Certainly, the utility model is not got rid of yet and is adopted alternate manner to make the low-expansion alloy layer fix and be wrapped on the round strip steel core.Set low-expansion alloy layer can be made by iron-nickel alloy or teleoseal material, is the iron-nickel alloy material of 4J36,4J43 or teleoseal material that model is 4J44,4J42,4J32 etc. as model.
The round strip steel core that the utility model adopted can be made less than 0.1% steel (being the alleged electrical sheets of those skilled in the art) by phosphorus content usually, as being that the steel (phosphorus content is less than or equal to 0.08% steel) of 08F are made by model.
In addition, in the utility model, above-mentioned copper-clad coating can be served as by copper sleeve or copper-clad layer usually.
Compared with the aforementioned existing similar products, because the core of the utility model Dumet wire wire rod is made of with the low-expansion alloy layer that is wrapped on this circle strip steel core circle strip steel core, that is by circle strip steel core, the low-expansion alloy layer has become the Dumet wire wire rod jointly with copper-clad coating three parts, this Dumet wire wire rod has the advantage of being convenient to adjust the radial and axial coefficient of expansion, its mechanism is: a, when the another kind of metal of a kind of metallic cover, can radially produce new radial expansion coefficient at it, herein, inserted and put the low-expansion alloy layer between circle strip steel core and the copper-clad coating, radial dimension and component content according to the three can derive from the radial expansion coefficient that makes new advances, thereby can allow the overall radial expansion coefficient of Dumet wire wire rod and the aforementioned radial expansion coefficient that is used for soft (lead) glass of sealing-in adapt easily; B, in the technical program, the main body of Dumet wire wire rod is circle strip steel core, this round strip steel core as main body is coated by the low-expansion alloy layer and after constituting core, and the axial expansion coefficient of this core can be subjected to the influence of low-expansion alloy layer and be lower than the axial expansion coefficient of round strip steel core self.Adopt the Dumet wire wire rod of ternary structural both to help reducing the cost of manufacture of product, guaranteed that again product can have the axial expansion coefficient that soft (lead) glassy phase with sealing-in adapts to.
Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.
