C86200 copper tube is not made from pure copper but is actually a high-strength manganese bronze alloy, primarily composed of copper, zinc, and a significant addition of manganese. This specific composition places it within the family of wrought copper-zinc alloys known for their exceptional mechanical properties rather than high electrical conductivity. As a result, its primary value lies in its superior strength, durability, and wear resistance, making it a preferred material for demanding structural and mechanical applications rather than for electrical or standard plumbing purposes.
In practical use, C86200 is renowned for its excellent machinability and ability to withstand high stress. It is commonly fabricated into components like pump rods, valve stems, gears, and bearings that operate under heavy loads, shock, and abrasive conditions. The alloy also demonstrates good corrosion resistance in many environments and superior fatigue strength, meaning it can endure repeated stress cycles without failure. This combination of easy fabrication, formidable strength, and wear characteristics makes C86200 tube a reliable engineering material for heavy-duty industrial and marine applications.
