Arsenical Copper Sheets, Rods, Bars & Tubes
Product Overview
Arsenical Copper is a specialized copper alloy containing a controlled addition of arsenic, developed to significantly enhance resistance to corrosion, dezincification, and hydrogen embrittlement, particularly in mildly aggressive and high-temperature environments. R V Metal Corporation supplies premium quality Arsenical Copper Sheets, Rods, Bars, and Tubes manufactured to precise metallurgical standards for demanding industrial applications. The presence of arsenic improves the alloy’s performance in boiler systems, heat exchangers, condensers, and water handling equipment where pure copper may suffer long-term degradation. These products retain excellent thermal and electrical conductivity while offering superior strength, creep resistance, and durability under continuous service conditions. Available in multiple tempers, sizes, and international specifications, Arsenical Copper products from R V Metal Corporation are trusted across power generation, marine, chemical processing, and heavy engineering industries for their consistent quality, reliability, and extended service life.
