Cast iron fine chips at Alu block cause problems
Hi all, I have met with the following problem. Our customer, a large automotive producer, now during holiday season, prolonged the exposure of Alu blocks with these chips that are hardly accessible, from 1 shift to 2-3 (during weekend)-it just stays freely on the line. Normally, they are washed away in further steps. But now, these chips get dry and make very uneasily removable crusts, and one can also watch the rust traces of corrosion likely galvanic type where two metals with different potential are in touch, on Al block (engine).
