Abstract

This invention relates to a copper covered aluminum-magnesium alloy thread, in addition to a preparing method. The aluminum-magnesium alloy is covered with copper, wherein the aluminum-magnesium alloy content reach to 99.6%, and the aluminum content is 0.7-4.5%. The preparing method comprises the following steps: a, rounding; b, cleaning; c, deburring; d, coating and welding; e, drafting bonding; f, drafting reducing; g, article associating. The thread has a similar conductivity property and mechanics property to copper wire, while the signal transmission property and barrier effect are superior to copper wire and aluminum-magnesium alloy thread. In the same diameter, the length of one ton copper covered aluminum-magnesium alloy thread is 2.5-2.7 times than one ton copper wire.

Description

technical field [0001] The invention relates to a copper-clad aluminum-magnesium alloy wire and a preparation method thereof. Background technique [0002] Audio and video cables, computer cables, audio coils, automotive cables, etc. require materials with good electrical conductivity, signal transmission performance and mechanical properties, so they are generally made of pure copper wire. high cost. At present, pure copper wire or aluminum-magnesium alloy wire is generally used to make shielding braided mesh. Because the shielding performance of the material is relatively simple, it is impossible to have good mechanical properties, electrical conductivity and magnetic permeability at the same time, so the application range is relatively narrow. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides a copper-clad aluminum-magnesium alloy wire with good mechanical properties, electrical conductivity, signal transm...
