Gary from the castinghobby Yahoo list scanned this metal and here are the results:
We brought the sample into the field of the Death Ray and got the following results. All elements that responded are listed but in the case of an element marked Death Ray Threshold. The Error shown to the side is essentially the Standard Deviation and the reported value +/- the error has a 99.73% propability of being correct, You could think of it as the content range of the element.
The results of the test only report what is present in the sample and not necessarily what is in alloy solution. For example W is reported as being predent in trace amounts but it is very unlikely that it is in solution with anything. It is more likely that it is present as a residue from a carbide tool used to machine some of the scrap or something similar in the past. When we first started using the gun we had some readings that were so high for Si that they could not be believed. Doing a CSA (Common Sense Analysis) something was wrong. What we found was that the operator was sanding the part to remove surface rust with Silicon Carbide paper and the gun was picking up the residue.
Results are:
Element % Error
Zn 52.107% +/-0.207% Cu 44.337% +/-0.231% Pb 1.957% +/-0.033% Al 0.760% +/-0.331% Ni 0.412% +/-0.010% Sn 0.134% +/-0.008% Fe 0.120% +/-0.008% Cr 0.062% +/-0.007% Co 0.036% +/-0.013% Ti 0.032% +/-0.004% Zr 0.003% +/-0.001% W Si Mn P Ag Bi Sb Pd V Se Ru Mo Nb S Mg
The Death Ray Software tries to alloy match this to the closest commerical alloy that is in its database which is fairly extensive. Sometimes thaer will be no match especially ifsurface contamination is high. In this case it alloy matched to C342PbBs or C332PbBs.
