ASTM B122 Sheet Plate is included in the specification of ASTM B122, which covers strips, sheets and plates of Copper Nickel alloys of the likes of Cupro Nickel 70/30 and Cupro Nickel 90/10 and also UNS C71500 and UNS C70600. To these alloys of Cupro Nickel, are added small amounts of manganese and iron and this serves to increase the corrosion resistance of this material in waters with high-velocity, including the likes of seawater. Cupro Nickel Plate are of immense use to designers, as due to the addition of nickel, these sheets are available in various colors from silver, to light rose.

Amongst the most versatile, durable and attractive copper alloys that can be got today, is none other than Cupro Nickel 70/30 Plate. It offers superb resistance to stress corrosion cracking, corrosion and biological fouling. As such, plates made from this material and also Cupro Nickel 90/10 Plate, are used in a number of applications and industries such as components of ships, coinage, heat exchangers, medical equipment touch surface, power plant condenser tubes, etc.
ASTM B122 Strip include copper-nickel alloy strips, plates, rolled bars and sheets made from alloys of UNS C71500 and UNS C70600. Plates, sheets and strips of ASTM B122 are manufactured by the process of cold working or hot working. If needed, annealing is done, so as to produce a structure that is uniform and wrought and meets the temper properties that have been specified.

ASTM B122 / B122M - 16

ASTM B122 is a Standard Specification for Copper-Nickel-Tin Alloy, Copper-Nickel-Zinc Alloy (Nickel Silver), and Copper-Nickel Alloy Plate, Sheet, Strip, and Rolled Bar

Copper nickel alloys are alloys which have and can maintain their moderate strength as well as thermal stability even when exposed to high temperature levels. The ASTM B122 alloys ability to highly resist oxidation corrosion is visible in moist air and steam. Copper nickel alloys like the ASTM B122 can have their nickel content ranging from about 2 to 30%, thereby offering high resistance to oxidation as well as stress corrosion cracking resistance.

As typical of Copper nickel alloys, the ASTM B 122/B122m too has good fabricability and high inherent resistance to biofouling. The addition of niobium, manganese, iron and or chromium in the ASTM B122 alloys is known to improve their resistance to corrosion as well as the alloys tensile strength.

ASTM B122 UNS C70600 is a Copper Nickel Alloy which chemically consists of 90% copper with 10% of the alloy being Nickel. The ASTM B122 C70600 is also referred to as UNS C70600. The key feature of the ASTM B122 UNS C70600 is the alloy’s performance in waters containing chemicals like hydrogen sulphide and the prevention of erosion as well as galvanic corrosion. Typically 90/10 Cu Ni alloys are widely used as they tend to be rather inexpensive and are easily available. Due to the presence of significant amounts of metals such as manganese and iron, 90/10 copper nickel alloys or the ASTM B122 UNS C70600 tends to have great resistance to sea water corrosion.

ASTM B122 C71500 or UNS C71500  is also referred to as C715 Cupro-Nickel. This alloy chemically consists of  about 70 percent copper and 30 percent Nickel. Alloy C715 has a lower conductivity as compared to UNS C70600. C71500 Copper Nickel is an alloy which finds use in many sectors such as oil and gas, marine industry as well as defence applications. In the marine industry, the ASTM B122 C71500 can be applied to in conditions that could require moderate-to-high sea water corrosion concern is present. For example, the alloy is used in the manufacture of pumps, valves, and high-pressure steam lines. C715 Cupro-Nickel ( Cu Ni 70/30 ) alloy that is almost entirely resistant to stress corrosion. The addition of small amounts of elements such as iron and manganese make 70-30 Cu-Ni ideal for use in applications which involves high-velocity polluted seawater. Other properties of the UNS C71500 or 70-30 Copper-Nickel include its strength, workability, formability as well as weldability. Benefits of using the ASTM B122 C71500 include the alloy’s High strength, High impact resistance, excellent resistance to corrosion & moderate machinability.

The specification for ASTM B122-16 covers the requirements for components like plates, sheets, strips, and rolled bars produced in copper-nickel-tin, copper-nickel-zinc, and copper-nickel alloy or made from UNS C70600, C70620, C71000, C71500, C71520, C72200, C72500, C75200, C73500, C74000, C74500, C76200, or C77000 alloy.

ASTM B 122/B122m is a specification that covers the requirements for either copper-nickel-zinc alloy , or copper-nickel alloy or copper-nickel-tin alloy plates, sheets, strips, and rolled bars manufactured from UNS C70620, C71000, C70600, C71500, C71520, C72200, C72500, C73500, C74000, C74500, C75200, C76200, or C77000 alloy. Each product as specified by the ASTM B122/B122m must be manufactured by either hot working or cold working, and annealed if required, in order to produce a uniform wrought structure that meets the specified temper properties. The ASTM B122 Pdf specification also contains information on the standard of tempers used for as well as the tensile strengths of hot-rolled, cold-rolled, and annealed tempers. Grain size of the component is the standard requirement for all products in the annealed tempers as mentioned in the ASTM B122 Pdf.

ASTM B122 specification establishes the requirements for copper-nickel-tin, copper-nickel-zinc, and cupro nickel plate, sheets, strips, and rolled bars made from UNS C70600, C70620, C71000, C71500, C71520, C72200, C72500, C73500, C74000, C74500, C75200, C76200, or C77000 alloy.
