Product Overview

What are Copper C12200 (DHP) Threaded Rods?

Copper C12200 (DHP) threaded rods are high-conductivity, deoxidized copper fasteners manufactured from UNS C12200 bar stock, conforming to ASTM B187 and B8/B8M standards. These rods are produced using deoxidized high phosphorus (DHP) copper, which offers excellent resistance to hydrogen embrittlement and superior weldability, making them ideal for electrical, plumbing, and HVAC applications.

With a minimum copper content of 99.9% and a phosphorus range of 0.015-0.040%, Copper C12200 threaded rods combine outstanding electrical and thermal conductivity with excellent corrosion resistance in water, steam, and mildly aggressive environments. They are widely specified for electrical busbar connections, earthing systems, and industrial process equipment where non-magnetic, non-sparking, and corrosion-resistant fasteners are required.

Material Chemistry

Copper C12200 (DHP) Chemical Composition

Copper C12200 (DHP) Threaded Rods 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.

Why Copper C12200 (DHP) Alloy Composition Matters for Threaded Rods

High Copper Content (99.9%) — Conductivity
The extremely high copper content ensures excellent electrical and thermal conductivity, making C12200 threaded rods ideal for electrical busbars, earthing, and bonding applications.
Phosphorus (0.015–0.040%) — Deoxidation
Phosphorus acts as a deoxidizer, improving weldability and resistance to hydrogen embrittlement, which is critical for threaded rods used in plumbing and HVAC systems.
Low Oxygen — Corrosion Resistance
The low oxygen content in DHP copper enhances resistance to corrosion in water, steam, and mildly aggressive environments, ensuring long service life for fasteners.

Browse expert answers to common questions about Copper C12200 (DHP) Threaded Rods from RealBolt — covering alloy selection, ATEX Zone 1 compliance, dezincification resistance, ASTM standard, sizes, and EN 10204 documentation. Contact our technical team directly for project-specific guidance on Copper C12200 (DHP) threaded rods selection and pricing.
Copper C12200 (DHP) threaded rods are available to DIN 975 (full thread), DIN 976 (stud bolts), ASME B18.31.3 (inch), and ISO 898-1 (mechanical properties). Custom thread forms such as BSW, BSF, and Whitworth can be supplied on request with a typical lead time of 10-15 working days.
Use copper-based anti-seize compound (such as Jet-Lube Kopr-Kote or Loctite LB 8008) on threads and nut bearing faces. This prevents galling and ensures consistent torque. Avoid nickel-based or zinc-based anti-seize, as these may cause galvanic corrosion with copper.
Yes – Copper C12200 (DHP) threaded rods offer 97% IACS conductivity and are the industry standard for earthing, bonding, and busbar connections in substations, switchgear, and lightning protection systems. Their non-magnetic and corrosion-resistant properties make them ideal for electrical applications.
