Testing and analysis methods for high-silicon aluminum alloys

At the same time, I suggest that you upload your analysis method so we can learn from it together, okay? Only by communicating together can we improve together

It is recommended that the person in question check these websites for the above national standards: Links for free download of the standards (from an online forum): http://bbs.hcbbs.com/thread-390043-1-1.html

For the testing of silicon-aluminum alloys, the following standard can be referred to: «YB/T 178.1-2000 | Chemical analysis methods for silicon-aluminum alloys and silicon-barium aluminum alloys»； \"GB/T 20975.5-2008 Methods for chemical analysis of aluminum and aluminum alloys\" ； \"Method for emission spectroscopic analysis of silicon, iron, magnesium, and copper in vacuum silicon-aluminum alloys SJ 3198-1989\" ； \"Methods for chemical analysis of aluminum and aluminum alloys – Determination of silicon content by gravimetric method GB/T 6987.5-2001\", \"GB/T 20975.5-2008 Methods for chemical analysis of aluminum and aluminum alloys\". In addition, XRD can also be used to characterize the crystal phases ； SEM-EDS for characterizing the microstructure and rough quantification ； XRF elemental analysis is used to characterize element contents and other such methods.

We are very grateful for the information provided by our friends above. The method we currently use is to incorporate high-silicon aluminum alloys into pure aluminum, raising the aluminum content to 70% and reducing the silicon content to 30%. Measure it again with an optical emission spectrometer. Such a method is troublesome, time-consuming, labor-intensive, and requires plenty of materials. Also, could someone tell me where I can find aluminum-silicon alloy standards with 70%, 60%, or 50% silicon content for use with optical emission spectrometers? Thank you

Are alloys with a silicon content of >50% still called aluminum alloys? Is it more accurate to call it a silicon alloy? Is it better to use a method of removing impurities? This post was last edited by chinaxm on 2009-2-18 11:09.]

What does ferroalloy include? Could you provide the analysis methods for them?
