Brakkie Posted January 19, 2009 Share Posted January 19, 2009 (edited) It all depends on your source but it normally refers to German Black. Which is very fine aluminium ranging anywhere around 5 micron. It's not used much in pyrotechnics except for flash and some star mixes/primes. What sort of aluminium are you after? Since German Black isn't something that a newbie actually needs. Edit: Xetap you definetly got a point but there are some sellers that don't really put much information on their website but still deliver good products.
