Abstract

The invention relates to a coaxial cable-shielding corrosion-resistant aluminum-magnesium alloy wire and a processing method thereof. The aluminum-magnesium alloy wire comprises the following components by weight percentage: 3.0-3.6 percent of magnesium, 0.18-0.30 percent of chromium, 0.2-0.6 percent of boron and aluminum in balancing amount. The coaxial cable-shielding corrosion-resistant aluminum-magnesium alloy wire is prepared by a process flow of smelting, drawing molding, heat treatment, roughly drawing, heat treatment, finely drawing and annealing and the like. The coaxial cable-shielding corrosion-resistant aluminum-magnesium alloy wire is scientific and reasonable in formulation of material components, advanced and simple in production process, high in efficiency, low in cost and resistivity and high in tensile strength and breaking elongation; the resistivity at the temperature of 20DEG C is less than or equal to 0.052 ohmmm<2> / m; the demands of the market can be met; the coaxial cable-shielding corrosion-resistant aluminum-magnesium alloy wire is an ideal coaxial cable shielding material; the coaxial cable-shielding and corrosion-resistant performance, the tensile strength and the breaking elongation can be improved; and compared with a copper wire, the aluminum-magnesium alloy wire is poor in recovery value, so that a cable stealing phenomenon can be reduced and avoided.

Description

technical field [0001] The invention relates to an anti-corrosion aluminum-magnesium alloy wire for coaxial cable shielding and a production method for the alloy wire, belonging to the technical field of new materials. Background technique [0002] The braiding layer of the coaxial cable is generally made of tinned copper wire or aluminum-magnesium alloy wire. Tinned copper wire has good shielding performance, but the cost is high. Aluminum-magnesium alloy wire has light specific gravity, low cost, and anti-galvanic corrosion. The current aluminum-magnesium alloy wire used for coaxial cable braiding shielding contains aluminum, magnesium, chromium and other components, and is completed by melting, forming, heat treatment, stretching and other processes. The existing aluminum-magnesium alloy wire has high resistivity, and its tensile strength and elongation at break are not ideal. Therefore, although the cost of tinned copper wire is high, tinned copper wire is still used fo...

The existing aluminum-magnesium alloy wire has high resistivity, and the tensile strength and elongation at break are not ideal

Therefore, although the cost of tinned copper wire is high, tinned copper wire is still used for the braiding layer of some coaxial cables, resulting in the waste of precious copper materials, especially the high recycling value of copper materials, resulting in cable theft in some places, serious Affect industrial and agricultural production and people's normal life
