Product Overview

C12200 copper, commonly referred to as DHP copper, is a phosphorus-deoxidized copper grade containing high copper purity and controlled residual phosphorus content. It is manufactured to ASTM B280, ASTM B75, and related standards for applications requiring reliable fabrication and corrosion resistance.

Produced through deoxidation refining processes, C12200 copper offers excellent welding, brazing, and forming performance while minimizing the risk of hydrogen embrittlement. Its balanced mechanical properties and stable thermal conductivity make it suitable for a wide range of industrial and thermal systems.

C12200 copper is extensively used in air conditioning systems, refrigeration tubing, plumbing equipment, and heat exchangers where durability and processability are essential. It is widely applied across HVAC, construction, energy, and general engineering industries.

C12200 Deoxidized High-Phosphorus (DHP) Copper — FAQ

Practical FAQ on C12200 DHP copper, ASTM specs, properties and why it is the plumbing/HVAC tube standard.

C12200 is phosphorus-deoxidized copper with Cu ≥99.90% and phosphorus 0.015–0.040%. The higher phosphorus versus DLP gives excellent brazing and welding behavior, making it the standard plumbing and HVAC tube copper.
ASTM B152 (sheet/strip/plate), B88 (water tube), B68 (seamless copper tube) and B280 (ACR tube) cover C12200; it is widely supplied as tube, sheet, strip and rod.
Conductivity is about 85% IACS, with annealed UTS ~195–250 MPa and elongation ~35–45%. It is not prone to hydrogen embrittlement and joins readily by brazing or soldering.
Its phosphorus deoxidation removes oxygen, so it brazes and welds cleanly without embrittlement, and it meets potable-water and refrigeration standards (B88/B68/B280). It is the workhorse for water tube, heat-exchanger tube and refrigerant line set.
Linsy supplies C12200 tube, sheet, strip and rod to ASTM with an MTR/MTC, SGS on request, and RoHS/REACH support. Typical lead time is 10–60 days with low MOQ and a 1-hour quoting response.
