Import Cast Magnesium Anode Rods For Water Heaters — Buy in Bulk from Supplier in China

The cast magnesium anode rods from Jiaozuo Yirui Magnesium Alloy Co., Ltd. are sacrificial corrosion protection devices designed for residential and commercial water heaters. They are manufactured from high-purity magnesium alloy, typically containing 99.9% elemental magnesium with trace additions of aluminum and zinc to improve mechanical properties. These rods are cast to shape and fitted with a central steel core for structural support and easy installation.

The alloy composition is standard for anode rods used in soft to moderately hard water conditions. Typical purity levels exceed 99.5%, with aluminum content around 0.3% to 0.7% and zinc below 0.2%. These additives reduce passivation and extend service life. The casting process ensures a dense, low-porosity structure, minimizing premature failure. The steel core is usually low-carbon steel, electroplated with zinc to resist internal corrosion.

These rods are purchased by water heater manufacturers, plumbing distributors, and maintenance contractors serving residential markets. They are compatible with most standard tank sizes from 30 to 80 gallons. Trade terms are not specified, but bulk orders typically ship in cartons of 10 to 50 units, packed with foam inserts. Lead time and MOQ are not stated and must be confirmed directly with the supplier. Installation follows standard industry practice using a 3/4-inch NPT thread.

Jiaozuo Yirui Magnesium Alloy Co., Ltd. is a Chinese manufacturer based in Henan Province, producing magnesium alloy products for industrial applications. The supplier is registered as an imported entity with harbor-level trust verification. The listing provides no details on production volume, years of operation, workforce size, or quality certifications. The physical address is listed, but no third-party audit reports or client references are mentioned.

The company's profile does not indicate whether it holds ISO certification, performs electrochemical testing, or maintains batch traceability. Response rate and average response time are zero, suggesting no active buyer support channel. Buyers should treat this as a production facility with capability in casting magnesium components but no public evidence of quality control systems beyond basic export readiness.
