Copper Nickel Alloy Flange ASTM B283 C70620 WNRF BLRF B16.5 CL150

ASTM B283 specifies requirements for forged copper and copper alloy components, including flanges, fittings, and other pressure-retaining parts.

The UNS C70620 alloy is a variant of the standard 90-10 Copper-Nickel (Cu-Ni) alloy (UNS C70600). While C70600 has a well-defined composition, C70620 may include slight modifications (possibly with adjusted iron or manganese content for improved performance).

Typical Chemical Composition of UNS C70620 (Estimated)

Since C70620 is not as widely documented as C70600, its composition is likely similar but may have minor adjustments. Below is a comparison:

Element	UNS C70600 (Standard 90-10 CuNi)	UNS C70620 (Estimated, based on variants)
Copper (Cu)	86.5 - 90.0%	86 - 90%
Nickel (Ni)	9.0 - 11.0%	9 - 11%
Iron (Fe)	1.0 - 1.8%	Possibly higher (1.5 - 2.5%)
Manganese (Mn)	0.5 - 1.0%	Possibly adjusted (0.5 - 1.5%)
Zinc (Zn)	≤ 1.0%	≤ 1.0%
Lead (Pb)	≤ 0.05%	≤ 0.05%
Other impurities	≤ 0.5%	≤ 0.5%

Key Differences (Possible in C70620 vs. C70600)

- Higher Iron (Fe): May enhance erosion-corrosion resistance in seawater.

- Adjusted Manganese (Mn): Can improve mechanical strength and weldability.

- Tighter control on impurities for specific industrial uses.

Common Applications:

- Marine environments (seawater piping, shipbuilding).

- Oil & gas (offshore platforms, desalination plants).

- Chemical processing (corrosion-resistant piping).

Flange Specifications (if applicable):

- Type: Likely a weld neck, slip-on, or blind flange (depends on the application).

- Pressure Rating: Typically Class 150, 300, 600, etc.(ASME B16.5 for standard sizes).

- Dimensions: Follows ASME B16.5 (for standard pipe flanges).

Weld Neck Flanges (WN Flanges) are designed for use in high-pressure systems and are commonly used with ASTM B151 C70600 (Copper-Nickel C70600) in marine and industrial applications due to the alloy’s excellent corrosion resistance.
