High-Quality Copper Nickel Tubing C70600 90/10 & C71500 70/30 Grades

Product Description

Cupronickel or copper-nickel is an alloy of copper that contains nickel and strengthening elements, such as iron and manganese. Cupronickel is highly resistant to corrosion in seawater, because its electrode potential is adjusted to be neutral with regard to seawater. Because of this, it is used for piping, heat exchangers and condensers in seawater systems, as well as marine hardware, and sometimes for the propellers, crankshafts and hulls of premium tugboats, fishing boats and other working boats.
A more familiar common use is in silver-coloured modern circulation coins. A typical mix is 75% copper, 25% nickel, and a trace amount of manganese. In the past, true silver coins were debased with cupronickel. Despite high copper content, cupronickel is silver in colour.
Thermocouples and resistors whose resistance is stable across changes in temperature contain the 55% copper-45% nickel alloy constantan.

C70600 (90/10 copper-nickel) is a corrosion-resistant alloy, primarily composed of 90% copper and 10% nickel. It is widely used in marine environments, desalination plants, and heat exchangers due to its excellent resistance to seawater corrosion, biofouling, and high ductility. It is available as plates, tubes, and fittings

FAQ

Q1: Are you a trading company or a manufacturer? How do I know I am getting the best quality directly from the source?
A1: We are both. We own and operate our own plate mill, giving us full control over the metallurgical properties, dimensional tolerances, and surface quality of our core products. However, we also function as a comprehensive supply chain management company.
Because we are the manufacturer, there are no middlemen markups on our mill-produced materials. When you source from ZYTC Alloy, you are dealing directly with the producer. Our supply chain division simply extends this "factory-direct" quality control to sourced products, ensuring that every item—whether from our mill or our partners—meets our stringent ZYTC standards before it reaches your facility.
Q2: How do you ensure a stable supply and competitive pricing in a volatile raw material market?
A2: Our unique "Manufacturer + Supply Chain Manager" model is designed specifically to protect you from market volatility.
Raw Material Control: As a mill owner, we strategically stockpile raw materials (nickel, chromium, molybdenum, etc.) to buffer against sudden price spikes.
Integrated Procurement: We don't just sell what we make; we source what you need. By consolidating your demand for both mill-direct plates and specialized supply chain items, we leverage higher total volume to secure the best market rates.
Cost Transparency: Because we control the production cost at the mill level, we can offer more stable long-term pricing than pure traders who rely solely on spot market purchases.
Q3: What is your typical lead time? Can you handle urgent or "Just-in-Time" (JIT) requirements?
A3: Lead times vary by specification, but our integrated structure allows us to offer three distinct advantages:
Standard Orders: Within 7–15 days.
Custom Orders: According to the quantity and material grade.
Urgent/JIT Needs:  If you need a specific non-mill item urgently, our procurement team can often bypass standard lead times to meet critical project deadlines.
