Problems solved by technology

[0002] With the rapid development of my country's economy, copper alloys are more and more widely used, especially cast silicon bronze is widely used in shipbuilding, mechanical processing, railway transportation and other industries. At the same time, product competition is more intense, and users have higher and higher requirements for product quality. , continuous improvement of detection methods, advanced chemical composition detection instruments, and the wide application of photoelectric direct reading spectrum plasma emission spectrometers have rapidly expanded the market for standard samples for spectral analysis. Currently, standard samples on the market cannot meet the requirements for use. In order to meet the needs of the market, Developed Qsi0.6-2 copper alloy standard sample, on the basis of GB / T5321-2001 product standard, added three elements (Zn, Al, Sn,) to meet market demand
