Abstract
The utility model provides a copper-clad aluminum-magnesium alloy double-metal wire for data transmission. The copper-clad aluminum-magnesium alloy double-metal wire comprises an aluminum-magnesium alloy core and a copper layer plated on the aluminum-magnesium alloy core, wherein the volume of copper is one-sixth to one-eighth of that of aluminum-magnesium alloy. The double-metal wire shares the excellent conductive performance of copper and has the characteristics of small specific gravity, high tensile strength and good flexibility of aluminum-magnesium alloy. Therefore, the copper-clad aluminum-magnesium alloy double-metal wire is used as a substitute for pure copper served as materials for preparing data transmission cables, and can be widely applied in the data transmission fields of communication, networks and the like.
Description
Technical field
The utility model relates to a kind of bimetallic conductor material, refer in particular to be mainly used in communicating by letter, the transfer of data copper clad aluminum-magnesium alloy double-metal in the field such as network.
Background technology
The former employing pure copper wire of the wire of transfer of data is made.Because the anxiety of copper resource causes skyrocketing of price, the substitute of various fine copper will be sought by every possible means by manufacturer, due to the kelvin effect in transmitting procedure, make the cable conductors core can be with certain cheap metal material instead of copper, can make cost of raw material decrease like this and the conductivity of cable products still can be up to state standards.Therefore people have invented copper cover aluminum and the alternative fine copper of copper aluminized products in succession, but copper cover aluminum because of the mode that adopts physical bond in the coating process easily make the copper layer and the aluminium core body inadequate in conjunction with rate, cause cracking, although and the copper aluminized products can realize the metallurgical binding of two kinds of metal materials, but because the tensile strength of aluminum is inadequate, often make diameter of wire just easily fracture below 0.5mm, and transfer of data often has multiply transmission heart yearn, diameter of wire is very thin and need to form fine rule is stranded, and therefore the wire product of better tensile strength need to be arranged.
Summary of the invention
The purpose of this utility model be overcome that existing copper alclad product easily ftractures, copper aluminized products easy defective of fracture in stranded process, a kind of transfer of data copper clad aluminum-magnesium alloy double-metal of can the decrease cost of raw material, having simultaneously high tensile strength is provided.
the technical scheme that its technical problem that solves the utility model adopts is: a kind of transfer of data copper clad aluminum-magnesium alloy double-metal, its inside is the almag conductor, plate again layer of copper on Al-Mg alloy core, make new bimetallic material have the good conductivity of copper concurrently, the proportion of magnalium is little, the characteristics that tensile strength is high, described copper layer volume is the 1/6-1/8 of Al-Mg alloy core, the length of the identical weight cable products that makes in this ratio is 2.5 times of fine copper cable products, its transmission performance can reach 6 class wire jumper standards, and it is not easy to crack in manufacturing process, fracture, can be widely used in communication, the data-signal transmission fields such as network.
Description of drawings
Fig. 1 is the structure chart of the utility model embodiment
Concrete execution mode
As shown in Figure 1: the utility model transfer of data is with the copper magnesium alloy bimetallic conductor of aluminizing, formed by Al-Mg alloy core 1 and the superincumbent copper layer 2 of plating, Al-Mg alloy core is the round body, after first aluminum-magnesium alloy wire being drawn to the technique diameter dimension during making, its surface is done to clean and the hacking processing, then Al-Mg alloy core 1 is soaked zinc after caustic soda, then clean through clear water and retreat zinc, process by electroplating technology with copper chloride, electric lithium copper.Copper volume after electroplating is the 1/6-1/8 of almag body, described magnesium alloy purity is greater than 99.8%, the content of magnesium is 1-4%, the bimetallic conductor that makes thus has good conductivity, proportion is little, tensile strength is high, around the good characteristics of property, can satisfy the needs of the field transfer of data such as communication, network when reducing production costs.
Claims (2)
1. a transfer of data copper clad aluminum-magnesium alloy double-metal, is characterized in that the copper (2) on Al-Mg alloy core (1) consists of described wire by Al-Mg alloy core (1) and plating.
2. transfer of data according to claim 1 copper clad aluminum-magnesium alloy double-metal, the volume that it is characterized in that described copper layer (2) is the 1/6-1/8 of the volume of Al-Mg alloy core (1).
