METAL ANALYZERS

摘要

The need to accurately buy and sort scrap has never been greater.Fortunately, today's electronic metal analyzers can offer scientific help.Though the scrap industry is full of legendary metal sorters who can identify different alloys just by sight or touch, the rest of us can always use a little help. Sometimes, that help comes in the form of magnets, acid, or grinding wheels for visual spark analysis-all relatively low-tech or no-tech approaches. And just as with those legendary sorters, the results are highly subjective, based on the user's experience and interpretation.
