The said AI-Mg alloy wire is composed of materials by wt.% as Mg of 3.0-3.5%, Cr of 0.2-0.3%, B of 0.2-0.4% and allowance of AI. The production process for preparing AI-Mg alloy wire is also disclosed.
Description
(1) technical field
The present invention relates to a kind of flat cable inner wire aluminum-magnesium alloy wire and production method thereof.
(2) background technology
In the prior art, the flat cable inner wire adopts copper product, though copper product has lower resistivity and ductility preferably, China's copper data comparatively lacks, and production cost is higher.And materials such as magnalium are abundant in china natural resources, are a kind of good method that saves production cost with aluminum-magnesium alloy wire as the flat cable inner wire, but need carry out brand-new exploration to the constituent of aluminum-magnesium alloy wire.The production method of existing general aluminum-magnesium alloy wire is: melting-first pulling shaping-heat treatment-rough-in draw-heat treatment-carefully draw-multifilament-check warehouse-in, the aluminum-magnesium alloy wire that adopts this production technology to produce also is difficult to meet the high anti-coiling requirement of flat cable inner wire.
(3) summary of the invention
The purpose of this invention is to provide a kind of flat cable inner wire aluminum-magnesium alloy wire, and provide the production method of this flat cable inner wire aluminum-magnesium alloy wire, this flat cable inner wire aluminum-magnesium alloy wire has good anti-coiling performance and electric conductivity, alternative flat cable inner wire copper cash, thus greatly reduce the production cost of flat cable inner wire.
The technical solution adopted for the present invention to solve the technical problems is: a kind of flat cable inner wire aluminum-magnesium alloy wire, it comprises Al-Mg alloy wire core and is wrapped in the outer lithiumation thing oxidation-resistant film of described Al-Mg alloy wire core that described Al-Mg alloy wire core is made up of following raw materials by weight percent:
Magnesium: 3.0～3.5%;
Chromium: 0.2～0.3%;
Boron: 0.2～0.4%;
Surplus is an aluminium.
The production method of flat cable inner wire aluminum-magnesium alloy wire of the present invention is: percentage composition meter by weight, with raw material magnesium 3.0～3.5%, chromium 0.2～0.3%, boron 0.2～0.4%, surplus aluminium, melting-first pulling shaping-heat treatment-rough-in draw-heat treatment-carefully draw, silk package after carefully drawing is on paying out machine, the silk volume is annealed through the tubular type annealing furnace of vacuum state from paying out machine, when the rotating speed of rotating speed at 800～1000 rev/mins, temperature is controlled at 380～430 ℃, by time and the temperature in the automatic monitored control system control annealing process, the alloy silk of pulling out from annealing furnace is around on the take-up pulley of admission machine after the anti-oxidation processing of lithiumation thing lotion preparation, check warehouse-in behind the multifilament.
Adopt the flat cable inner wire aluminum-magnesium alloy wire of proportioning of the present invention, it is conductor resistance≤136 Ω/km in the time of 20 ℃, tensile force 〉=6.1N, elongation at break 〉=8%.This flat cable inner wire aluminum-magnesium alloy wire has good anti-coiling performance and electric conductivity, alternative flat cable inner wire copper cash, thus greatly reduce the production cost of flat cable inner wire.
