Products Description

ASTM B111 C28000 tubing, sometimes referred to as Munz metal, contains 40% zinc and 60% copper. Its color resembles architectural bronze. Primarily composed of β-grains, C28000 tubing is harder, stronger, and more robust than brass with lower zinc content.

This tubing hardens quickly and is not well-suited for cold working, but it is easy to form or bend. C28000 tubing is widely used in construction, signage, and condenser panels.

C28000 tubing exhibits excellent bending and flaring properties, pull-out properties, and is suitable for electroplating. It is applicable to numerous fields, including curtain rods, heat exchangers, sanitary ducts, antenna masts, and components for various machinery and equipment.

 

C28000 pipes are available in a wide range of colors, including red, yellow, silver, and gold. These colored pipes are easy to mold and are therefore frequently used by architects and designers to enhance the interior and exterior appearance of buildings.

C28000 pipes are available in a full range of sizes, both standard and custom. If you require customized sizes, shapes, or specifications for your C28000 pipes, please send us your detailed requirements.

In addition, GNEE offers C28000 tubing in various shapes, including round, square, flat, hexagonal, oval, semi-circular, and other custom shapes.

What is a C28000 Tube?

C28000 tube refers to a tube whose chemical elements are copper and zinc with varying proportions.

The compound gives it the necessary strength and color for use in various sectors.

These applications include architectural applications and condenser plates.

 

What are the Characteristics of C28000 Tubes?

The characteristics of C28000 tubes that make them fit for their versatile use include:

Anti-wear

Highly ductile

Unique color

Anti-corrosive

Thermal and electrical conductivity

machinability

 

How do you Test the Quality of C28000 Tubes?

Quality testing not only ensures that you get the best C28000 tubes, but you also have durable tubes.

The production process of C28000 tubes subjects them to the following quality tests:

· Ultrasonic Test

This test helps in determining flaws such as defects and cracks on a C28000 tube.

The two types of ultrasonic tests available include contact ultrasonic test and immersion ultrasonic test.

It is an ideal method since it is non-hazardous and does not react with the tube.

However, the manual procedure makes it a slow process to use.

· Hydraulic Test

The essence of a hydraulic test is to analyze the pressure limits of a given C28000 tube.

This helps in understanding which tube to use on a given application.

It also helps to understand the strength of a given tube and the presence of any leakages.

· Eddy Current Test

It is an alternative test to ultrasonic test and helps in detecting the presence of any flaws such as cracks on a C28000 tube.

It involves passing an electric current through the tube using wire coils.

· Radiographic Test

A radiographic test analyzes the internal structure of a C28000 tube.

For useful analysis, you can use machine methods such as X-rays to analyze the surface structure properly.
