نحاس نحاسي 70/30

Introduction

Recently, our customers have started buying large quantities of cuni 70/30 pipes and flanges. We have been producing cuni 70/30 fittings for 20 years.

You may need knowledge about cuni70/30. Usually, communicate with customers about cuni70/10 and the problems they may encounter. Compiling this knowledge took me three days, and it’s worth reading.

What Is CuNi70/30

The cuni 70/30, also known as c71500, has a nickel content of 30 to 32 per cent and is more resistant to seawater corrosion. Excellent hardness and corrosion resistance, cuni70/30 is used in seawater and in large quantities in the chemical and nuclear industries.

Chemical Composition

Physical Properties

Here are the mechanicals of the cuni 70/30 that I’ve put together according to the standard for your reference.

Similar Grade

• DIN 17664 2.0882
• BS 2871 CN 107
• MIL-T-16420K ASTMB 466 C 71500

CuNi 70/30 Key Features

Each national standard has its own cuni 70/30 material grade. Below is my compilation of commonly used cuni 70/30 grades worldwide.

• Resistant to seawater corrosion and strong hardness, you can use it in seawater or high pressure environments.
• The cuni 70/30 material is flexible and can be cold worked into elbow and reducer fittings. It can also be hot machined and forged into your desired flange shape.
• Good thermal conductivity, excellent material you choose to use for heat exchangers.

CuNi70/30 Products

• CuNi70/30 Pipes You can see our cuni 70/30 tubes in stock. The cuni 70/30 tubes are produced by extrusion-drawing technology, and the tubes are supplied in a soft (fully annealed) state.
• CuNi70/30 Flanges， The cuni 70/30 flange comes in a variety of types as you can see.
• CuNi70/30 Pipe Fittings. The cuni 70/30 tee elbows are made from tubing by cold working and are supplied in a fully annealed condition.
