Import Extruded Magnesium Anodes Rod — Buy in Bulk from Supplier in China

Extruded magnesium anodes rod from Metal Challenge (Xian) Co., Ltd. are industrial-grade sacrificial anodes designed to protect water storage tanks and heating systems from galvanic corrosion. The product is manufactured using high-purity magnesium, with a minimum purity of 99.9% as confirmed by the supplier’s technical data. Each rod is extruded to ensure consistent grain structure and uniform surface exposure, enhancing electrochemical efficiency. Dimensions available include diameters from 25 mm to 50 mm and lengths from 300 mm to 1200 mm, tailored to standard water heater configurations.

The anodes are composed of high-purity magnesium with trace additions of manganese and aluminum to improve current output and reduce passivation, aligning with ASTM B843 and EN 12579 standards for sacrificial anodes. These compositions are typical for extruded magnesium anodes used in potable water systems and geothermal applications. The extrusion process eliminates porosity and ensures structural integrity under prolonged immersion, a key advantage over cast alternatives. Surface finish is smooth and free of machining marks, facilitating easy installation without requiring additional preparation.

These anodes are primarily purchased by manufacturers of residential and commercial water heaters, HVAC system integrators, and industrial plant maintenance teams operating in regions with hard water. They are commonly used in electric water tanks, boiler systems, and heat exchangers where cathodic protection is required. Packaging is typically in bulk cartons of 10 to 20 units, with desiccant to prevent surface oxidation. Trade terms offered include FOB Xi’an and CIF ports, with MOQ negotiable based on order volume. Buyers should confirm compatibility with tank lining materials before installation.
