ASTM B151 UNS C70600 Weld Neck Flange | CuNi 90/10 Flanges
ASTM B151 UNS C70600 weld neck flanges are copper-nickel (CuNi 90/10) alloy flanges designed for seawater and marine piping systems. With excellent resistance to corrosion, biofouling, and erosion, they are widely used in offshore, desalination, and heat exchanger applications.
What is ASTM B151 C70600 Flange?
ASTM B151 covers copper-nickel alloy rod and bar, which are used as starting materials for manufacturing flanges through forging and machining.
C70600 (CuNi 90/10) Composition:
- Copper (~90%)
- Nickel (9–11%)
- Iron and manganese additions
👉 This alloy is also known as:
- CuNi10Fe1.6Mn
- Werkstoff 2.0872
- UNS C70600
We are the professional manufacturer of ASTM B151 UNS C70600 WELD NECK FLANGE CuNi10Fe1.6Mn UNS 7060X FLANGES in China.These flanges are designed for marine, offshore, desalination, and power generation industries where excellent seawater corrosion resistance, biofouling resistance, and durability are critical.
UNS C70600 Flanges is made from a round bar of ASTM B151 UNS C70600 material,through forging and machining process.
CuNi10Fe1.6Mn 90-10 copper-nickel (C70600, CW352H), an alloy with 90% copper and 10% nickel, is the most commonly used alloy. It can be found in naval and commercial shipping, offshore oil and gas production as well as desalination and power generation. Alloys with 30% nickel content (C71500, C71640) and those which are more highly alloyed with aluminum, chromium or tin are used where greater resistance to seawater flow, sand abrasion, wear and galling, as well as higher mechanical properties, are required.
