Product Overview

What are Copper C12200 (DHP) Studs?

Copper C12200 (DHP) studs are double-ended threaded rods manufactured from phosphorus-deoxidized, high residual phosphorus copper, conforming to ASTM B62 and ASTM B151. With a minimum copper content of 99.9% and excellent thermal and electrical conductivity, these studs are widely used in applications requiring reliable electrical connections and corrosion resistance, especially in plumbing, heat exchangers, and marine hardware.

The deoxidized nature of C12200 ensures superior weldability and formability, making these studs ideal for brazed and soldered assemblies. Copper C12200 (DHP) studs are supplied with full traceability and are compliant with international standards for use in potable water systems and industrial piping.

Material Chemistry

Copper C12200 (DHP) Chemical Composition

Copper C12200 (DHP) Studs are produced from either tin-stabilized Naval Brass C46400 or aluminium-nickel-iron Aluminium Bronze C63000, with elemental limits per ASTM and MIL-B-24059. Tin (0.5–1%) in Naval Brass prevents dezincification in seawater; aluminium and nickel additions in Al Bronze C63000 provide non-sparking ATEX Zone 1 compliance.

Chemical Composition per ASTM B151

ElementComposition (%)
Copper (Cu)99.9% min
Phosphorus (P)0.015-0.040%
Oxygen (O)0.02% max
Other Elements0.05% max (total)
? All heats verified by NABL-accredited spectrometry. Conductivity and oxygen content certified per ASTM B151.

Why Copper C12200 (DHP) Alloy Composition Matters for Studs

High Copper Content — Conductivity & Corrosion Resistance
The 99.9% copper content ensures excellent electrical and thermal conductivity, making C12200 studs ideal for electrical busbars, earthing, and heat exchanger assemblies exposed to water and steam.
Phosphorus — Deoxidation & Weldability
Phosphorus deoxidizes the copper, preventing hydrogen embrittlement and allowing reliable brazing, welding, and soldering of studs in piping and electrical systems.
Low Oxygen — No Hydrogen Embrittlement
The low oxygen content (<0.02%) prevents the formation of copper oxides, ensuring mechanical integrity and ductility even after repeated thermal cycling.
