We, Piyush steel, are the leading supplier, exporter and also manufacturer of copper-nickel 70/30 (c71500) round bar. We are known for quality and excellent services. We have proven our reliability every time to the customers. All the industry norms are followed by us. We also know what are the guidelines and standards should be followed while manufacturing these bars. The international standards that we follow have made us one of the trusted producers outside the country as well.
Our designed bars are the most demanded product in almost all industry. The secret behind this popularity is the use of standard raw materials. The selection of material plays an imperative role in the manufacturing of bar. However, this is not the only reason. Other reasons include the great precision followed during manufacturing, the right use of technologies, proper inspection, and standards followed during the process and performing of crucial tests.
The bars that we serve are quite popular in marine and non-marine applications. They are also preferred for cryogenic applications. The bars don’t get contaminated from bacteria, fungi, and viruses as they are antimicrobial. Thus they survive under toughest conditions whereas other bars get contaminated and rusted causing huge damages to the industry.

Properties of bars
The copper-nickel 70/30 (c71500) round bar or UNS c71500 bars are often made in custom sizes and shapes. Thus we give an option to the customers to get according to their application needs making the designs more flexible. Our copper-nickel bars are simply not known for strength and durability but also for excellent properties such as corrosion resistance. The marine industry often demands such bars, therefore, we use the best alloy to make bars so that they don’t get damaged through corrosion. The seawater service of the copper-nickel alloy is best in comparison to nickel. It is almost 10 to 30 percent more suitable to be used in marine environments.
The pure copper-nickel alloy is not used to manufacture these bars. The manganese and iron are added to them which are responsible for their corrosion resistance properties. Other properties of this alloy that make the best choice for bars are as follows:

Test on bars
The test requirement depends on the situation where the testing methods can be performed on single bars or a batch of bars. The test checks for integrity and defects in a bar. Following are the necessary tests:
Packaging and dispatching
Each bar is color-coded, and labeled to define its size. The excess oil from bar is removed and a ring is inserted to avoid contact with other bars. They are then tied and packed in LDPE and again in HDPE. Lastly, they are transported to customers.
