Abstract

The invention discloses a high-strength high-conductivity aluminum alloy anode guide rod and a manufacturing method thereof. The high-strength high-conductivity aluminum alloy anode guide rod consistsof the following components in percentage by mass: 0.05 to 0.1 percent of Si, 0.20 to 0.30 percent of Fe, 0.02 to 0.03 percent of Ti, 0.01 to 0.02 percent of B, 0.70 to 0.80 percent of Mg and the balance of Al and unavoidable impurities, wherein the impurities are trace elements, each component of the impurities does not exceed 0.02 percent and the total amount of the impurities does not exceed 0.02 percent. The traditional process method for manufacturing an anode guide rod by using pure aluminum or adding a small amount of magnesium element (less than or equal to 0.5 percent) into pure aluminum is broken, high-iron electrolytic aluminum liquid of 99.6 percent is adopted, and the magnesium element content is increased to 0.7 to 0.8 percent, so the problem that the surface hardness of theanode guide rod is insufficient is effectively solved.

Description
