Copper Alloys Seamless Tubes are high-integrity, non-welded tubular products crafted from premium copper-based alloys, offering exceptional thermal conductivity, corrosion resistance, and formability for demanding industrial, marine, and energy applications.
Outstanding Formability & Joinability: Easily bent, flared, or brazed without cracking—reducing fabrication complexity and enhancing system reliability.
Biofouling Resistance: Copper’s inherent antimicrobial properties inhibit microbial growth in water systems, making it preferred for potable water and desalination plants.
Recyclability & Sustainability: Fully recyclable without property loss, aligning with global green manufacturing and circular economy initiatives.
Comprehensive Technical Specifications
Common Alloys & Designations:
C12200 (DHP – Phosphorus Deoxidized Copper): Excellent hot-working and welding characteristics; widely used in plumbing and heating.
