Copper Nickel 70/30 Round Bar

70/30 cu ni hex bars suppliers in UAE

Copper and nickel have an ancient history of use in piping systems because of their sturdy, corrosion resistant, and other excellent properties. Hence alloys with both in a 70/30 ratio, along with manganese and less iron, makes pipes and tubes of high strength and rust-free for a long time to save costs, time, and effort.

The copper nickel 70/30 round bar is a revised version of 90/10 to be less expensive and has more intergranular, cervix, and pitting resistance. Hence cupro nickel 70/30 round bar is best for demanding applications in offshore, marine, chemical processing, heat exchangers, condenser components, etc.

CuNi Alloy 70/30 Round Bar has less iron content than 90/10 to have more corrosion resistance. It has 310 MPa tensile strength, a high melting point of 2260 F or 1237 C, and 80-100 HB hardness. Hence, it finds use in applications needing high strength to withstand extreme temperatures and pressure.

Cu Ni 70/30 round bar being tough and rust-free for a long time, is best used in many industries. A few of its uses are in the petrochemical, chemical, oil & gas, power plant, energy, aerospace, food processing, paper & pulp industries, and others.

Is UNS No C71500 rod expensive?

Compared to 90/10, 70-30 Copper Nickel Rods are less expensive because of their lower copper content. But nickel replacing the 20% carbon to have around 30% UNS No C71500 Rod has many excellent properties for use in demanding environments.

DIN 2.0882 round rods have high corrosion resistance in polluted seawater and high-velocity water up to 4.5m/s. Also, it is easy to hard work, fabricate and weld 70/30 copper-nickel rods, not needing any special material consideration. Hence 70/30 copper-nickel rods are more expensive than most other rods of different alloys but with many unique properties and uses.

How do you weld Cu-Ni 70/30 hex bar?

Cu-Ni 70/30 Hex Bar though having high strength, is easy to weld, form, and machine. It is apart from the high resistance and excellent corrosion resistance. But it has limited tolerance for dilution by iron, and using welds with more than 10% iron may cause excessive fissures and hot cracks.

So choosing the right welding method for a 70/30 hex bar is essential from the many available. A few include gas-shielded arc, coated metal arc, seam welding, brazing, soldering, Oxyacetylene, and spot welding. Reputed suppliers offer 70/30 copper–nickel bars made from suitable welding methods per customers’ requirements.

Can ASTM B111 Cu-Ni 70/30 rods rust?

ASTM B111 Cu-Ni Alloy 70/30 Flat bars and rods have superior corrosion resistance even in polluted salt water. With only less than 1% iron fewer than in 90/10 copper nickel rods, it has high corrosion resistance. From ancient times, copper has been one of the rust-free metals used for piping systems, even in pyramids.

Hence, the question of ASTM B151 UNS C71500 rods rust, it does not rust for most applications. But it may rust after a long use without maintenance and other reasons. But only because of its rust-free property, it is ideal for many specific demanding applications.
