Copper Nickel 70/30 Round Bar

Copper nickel 70/30 round bar specifications

What is a copper nickel 70/30 round bar?

This bar has a chemical composition of 70% cu and 30% ni. A copper nickel 70/30 round bar also has iron and manganese. It shows brilliant resistance to corrosion, impingement, and barnacle contamination in marine applications, including seawater and polluted water.A cunifer 70/30 forged round bars may comprise aluminium, niobium, silicon, and beryllium for additional metallurgical properties.

We are a supplier of 70/30 cuni roundbar in India, and you can also inquire about the uses of cunifer 70/30 rod with us

What is a 70 30 copper nickel alloy round bar used for?

These bars deliver resistance to bio-fouling, making them useful for inhibiting microbial growth. Acopper nickel 70 30 alloy round bar has good weldability and supports fabrication. Industries like offshore drilling, chemical processing, and refrigeration benefit from these properties. A 70-30 cunifer round bars is also utilised in aeronautics, evaporators, and condensers. Applications in the marine sector range from propellers to components of pumps and flanges.

Each batch of cunifer 70/30 forged round bar and Cupro Nickel 70/30 Rounds is flattening tested extensively to guarantee its exceptional quality

How does flattening testing of cupro nickel 70/30 bars ensure their quality and reliability?

A flattening test checks the deformation ability of cu-ni alloy din 2.0882 flat bars, I.E., whether they handle stress without deformation. It guarantees performance and ductility. Manufacturers also perform non-destructive tests like positive material recognition and use eddy current to detect defects. A mill test certificateattests to the quality and performance of a cuni 70/30 square bar.
