One of our greatest secrets of alloy producing we promised to reveal in January 2010 (our news issue of 12.11.2009) is the new method of alloy quality diagnosis using gestation both the primary and the secondary aluminum smells. Thanks to the number of smells our degustators are able to define such metals and alloys which can make alloys defective if added. For example at some foundries at the process of casting there appear pellets with bad smell and the percentage of defects greatly increases. This is the result of critical accumulation of harmful, so called extrinsic admixtures. These admixtures should be got rid of at the stage of the first production of primary as well as secondary ingots. The matter is that admixture accumulation in the production cycles of a business within a certain time period will considerably increase the amount of defects. It is necessary to realize that extrinsic admixtures cannot be neutralized now; you just have to know where they are and cut the defected area like a surgeon.
