We separated the batches by - degassed castings - Tibor grain refined - Strontium moodified and a combination of degassed+tibor refined Our scrap rate after pressure test was about 10% in all cases, except for that without the grain refiner, which was out worst case scenario (0ver 20%). With...

Well, the results of our castings were pretty much the same, with the addition of strontium to the alloy. However we did notice a considerable improvement when TiBor was added to the alloy. The degasing didnt do much either, surprinsingly. Emilio

We are trying to reduce the leakers by degasing the metal and adding Tibor, but I am not sure about treating the alloy with a modifier (Strontium). I heard that by adding a modifier to the bath, the resulting alloy will have a structure more suitable to the formation of paths which will lead to...

Hi there. Would anybody in this forum know of a alloy modifier that will modify aluminum alloys (in our case, 356) so that the castings will have less chances to leak under pressure? We are developing a casting that needs to resist up to 70 psi pressures. emilio

The water we use is pretty clean - comes straight from the public pipelines, and we replace the tanks with clear water often. eSchein

Of all these companies, I havent seen one that will consider the influence of dycotes on the molds. I wonder if I missed something or whether insulation caused by these coatings have not been developed yet for casting simulators. eSchein

Hello there. I am trying to find out why aluminum castings suffer a color modification on its surfaces after heat treatment (T6/quenching). We use Foseco's dycotes in our dye casting process, and I wondered if these substances would react with the aluminum oxides on the parts surface, therefore...

hello there. Does anybody know of resources on casting simulation on the web? I am interested in aluminum castings simulators, but I don't know where to find references/articles about programs that are available out there. eschein
