| I don't see anything too crazy. Silicon is going to be foreign objects (dirt) while lead, tin, cooper, silver and aluminum will be bearing materials. Iron is from wear surfaces. I believe chrome and nickle may be wear surfaces as well. It's normal to see some amount of any of those materials, but there will be upper limits. Usually the only way to compare is to find an identical machine to compare numbers against or past numbers off the machine in question. | |
