Dear All, I am looking for an authentic statement or any references which can be utilised when there will be any dispute among any analytical findings of the elemental contents of any alloy. As we know, there are several analytical procedures used in metal analysis - which method has higher level of confidence?

In other words which method can be used as a referee test? I would appreciate if anybody can give some answers to it or any authentic references. Thank you,. The specifications to which the aluminum alloy is ordered should refer to acceptable analytical methods.

Choice of analytical method will depend upon alloy. The E34 methods are generally more accurate within given alloy concentration ranges.

The E method can quickly measure the various elements from a single sample and can generally detect lower concentrations of most alloying elements. However, the precision is poorer e. Wet chemistry is better for average alloy composition since it uses dissolved samples.

The emission methods are less accurate on heterogeneous alloys especially castings since conducted using solid samples; special splat quenched samples or multiple analyses can compensate. For each specification, measurable elemental ranges, analytical procedures and referenced specifications can be viewed at www. He passed away May 14, Rest in peace, Ken. Thank you for your hard work which the finishing world continues to benefit from.

Dear Mr. Ken Vlach, Thank you so much for your answer. Perhaps Wet Chemistry method would be ideal as a referee test. Thank you once again. Best regards, Basu. You're welcome. First use a fast, multi-element analysis technique to identify elements possibly out-of-spec.
