pyrokid Posted May 16, 2016 Share Posted May 16, 2016 Does anyone know any effects that use FeCu? I see that hobbychemicalsupply have it listed on their website. The only thing I can think of is attempting an exotic strobe composition. Does anyone have any experience with this material? Link to comment Share on other sites More sharing options...
FlaMtnBkr Posted May 16, 2016 Share Posted May 16, 2016 I'm sure it will make sparks. But not sure of any different effect it's used for. Though it seems like I saw a recent Chinese pyro patent that listed it but I will have to dig around to make sure. Link to comment Share on other sites More sharing options...
AzoMittle Posted May 16, 2016 Share Posted May 16, 2016 I'm actually struggling to come up with any formulas that use iron, I've got about 3 on hand, one of which is a sparkler and the other two being gold rain stars. This is just a guess but you could probably sub the FeCu for any composition that calls for a metal dust especially iron or copper dust, with different effect obviously, but HCS says it is 60% iron and 40% copper. Order a pound, try it out, post some videos and let us know. I found these, I bet the brass dust could be switched out for the Iron-Copper master alloy: Golden Rain #130....Potassium nitrate08....Sulfur03....Antimony sulphide03....Wood flour02....Ground glass01....Brass dust Golden Rain #204....Meal powder04....Sulfur02....Wood flour01....Ground glass01....Brass dust01....Potassium nitrateAd lib....Shellac alcohol Link to comment Share on other sites More sharing options...
