Chemical composition and analysis and test methods of copper alloy

copper alloy is a heavy metal nonferrous alloy composed of pure copper as the matrix and one or more lithium copper foils. The demand will continue to expand and other elements will form

commonly used copper alloys can be divided into brass, bronze and white copper

in addition to copper, according to different types, some other elements need to be added to copper alloys, such as aluminum, nickel, manganese, tin, silicon, lead, iron, zinc, beryllium, phosphorus, etc., and there are also a small amount of impurity elements. Analyzing and testing the composition and content of elements in copper alloy has become the key to control the material of copper alloy

common methods for the analysis and testing of elements in copper alloys are spectral analysis, atomic absorption spectrometry, photometric analysis and titration. Its analysis methods have their own advantages and disadvantages

Nanjing Lianchuang company can provide a complete set of solutions for chemical analysis of copper alloy, which is mainly suitable for small and medium-sized upstream and downstream enterprises to strengthen cooperation. With less investment and quick effect, the designers of Zhongchuang experimental machine manufacturers can make special designs according to the situation, which can meet the requirements of copper alloy production and incoming material testing

according to the different requirements of enterprises, the instrument can choose lc-bs3c three channel intelligent element analyzer, lc-bs6e six channel intelligent multi element analyzer, lc-8b computer multi element analyzer and other models

main technical parameters of the element analyzer:

1. Analysis method: photoelectric colorimetric analysis method

2. Measuring range: absorbance value 0 ~ 1.999a, concentration value 0 ~ 99.99%

3. Measurement accuracy: in line with the allowable difference specified in the national standards of the methods for chemical analysis of iron and steel and Ferroalloys and the methods for chemical analysis of nonferrous metals and alloys

main features of the element analyzer:

1 The instrument is used to analyze the contents of manganese, phosphorus, silicon, chromium, nickel, molybdenum, vanadium, titanium, aluminum, copper, magnesium, iron and other elements in steel and its alloys, non-ferrous metals and their alloys (aluminum alloys, copper alloys, zinc alloys, etc.), ores and other materials

2. It adopts microcomputer control and data processing, and can store multiple standard sample detection curves, with a wide range of analysis

3. The size of the casting roller, materials and internal cooling medium channel are the key The zero point and full degree of the instrument can be automatically adjusted without human intervention. It is easy to operate and has high reliability. Various auxiliary parameters such as date and heat number can be input, and the analysis and test results can be printed.

5. The instrument is reasonably designed, and the advanced cold light source technology is adopted, which makes the data more stable and can easily expand the variety and content range of measuring elements
