70-30 Cupro Nickel

Such Sheet or Plate is manufactured by hot or cold working, and annealed if required in order to b22 a uniform wrought structure to meets the specified temper properties. Cupro Nickel Alloy with small amounts of iron and manganese improves corrosion resistance in high-velocity waters, including seawater.

Cupro-Nickel are among the most attractive, durable and versatile copper alloys available.

Offering unique properties such as excellent resistance to biological fouling, corrosion and stress corrosion cracking, these alloys are used in a range of applications from heat exchangers, ship components and condenser tubes of power plants to coinage and even touch surfaces on medical equipment.


Nickel additions in these alloys allow designers to benefit from attractive color options ranging from light rose sstm silver. ASTM B Rolled Bars are known for the long subsequent processing they undergo secondary and tertiary aastm, until the final end products are produced.

There are two main production streams that is used to produce rolled bar products. The first stream is referred to as the integrated mill stream, which uses mostly iron ore to feed a blast furnace, which in turn supplies hot iron to a steel making operation.

The molten iron is commonly referred to as hot metal or, in its solid form, as pig iron. The second is the electric arc furnace EAFwhich primarily uses steel scrap as the aztm material.

Cupro Nickel (UNS C, ASTM B)

Both processes can produce ingots which are rolled into blooms or billets or strand cast blooms or billets. Steel ingot is the cast metal with porosity and blow-holes. The ingot is soaked at the hot rolling temperature and then rolled into blooms or billets or slabs.


The bloom has a square cross section.

A slab, also from ingot, has a rectangular cross-section, with an area of at least cm2 and width at least three times the thickness. A billet is rolled out of bloom, has at least 40 mm X 40 mm cross-section. Blooms h122 used for rolling structural products such as I-sections, channels, rail etc. Billets are rolled into bars, rods.

Bars and rods are raw materials for extrusion, drawing, forging, machining etc. Slabs are meant for rolling sheets, strips, plates, etc.
