Description:

Non-Smoking Non-Fuming Odorless Flux
MARVELUX® BULLET CASTING FLUX The Brownells MARVELUX® Bullet Casting Flux is a premier choice for both professional and hobbyist bullet casters, effectively reducing dross formation and enhancing the fluidity of bullet alloys. Introduced in 1971, MARVELUX® has been a trusted flux in the bullet casting community. Its non-corrosive nature ensures that iron and steel equipment remain free from rust, and it does not produce fumes that can cause corrosion, unlike sal-ammoniac-based fluxes. Regular use of MARVELUX® keeps casting pots clean and rust-free. Additionally, it is non-smoking, flameless, and odorless, providing a safer and more pleasant casting experience. MARVELUX® is superior to traditional fluxes like beeswax, tallow, paraffin, and rosin, as it doesn't emit unpleasant odors during use. Key Features: Non-Corrosive: Safe for iron and steel, preventing rust formation. Fume-Free: Does not emit corrosive fumes, ensuring a safer casting environment. Reduces Dross Formation: Enhances the fluidity of bullet alloys for better fill-out. User-Friendly: Non-smoking, flameless, and odorless, improving the casting experience. Specifications: Available Sizes: ½ lb. (8oz / 226g), 1 lb. (16oz / 453g), and 4 lb. (64oz / 1.8kg) jars. Application: Suitable for any lead alloy melt intended for casting bullets or swaging cores. Incorporating Brownells MARVELUX® Bullet Casting Flux into your bullet casting process ensures cleaner melts and higher-quality bullets, making it an essential component for achieving optimal casting results.

Brownells USA Best Flux I have found 09/11/2014

I have been casting for almost 50 years and like most old casters I used to use beeswax for a flux for my salvaged range metal. If you have used salvaged bullets you know you get a little bit of everything along with the lead. Wax as a flux smokes and sometimes ignites, but it does work.



However, once I tried a jar of Marvelux I have never used anything else. It is a coarse granular powder that stays on top of the lead. It doesn't take a lot of material to do the job and a one pound jar last a long time. Once stirred in it helps the metals blend and the impurities to bond together and rise to the top where they are easily skimmed off. It doesn't smoke and ignite and does a far better flux job than wax. The powder does tend to cake in the jar, but it is easily broken up with a spoon. I read one negative post about Marvelux causing rust and I honestly don't know what he is talking about, if anything it keeps my pot clean and free from buildup and certainly no rust. If you haven't tried this product then you are still doing things the hard way.

Not recommended

Brownells USA Be careful 24/09/2014

If you absolutely need something with minimal smoke/smell, Marvelux works OK. Be very careful though, as it is seriously hygroscopic (attracts moisture) and leaves a sticky, glassy residue that's hard to get rid of. I had bad rust problems when I used it, and threw away the rest of the can. I think it can work ok if you're very careful how you use it, but many/most serious casters hate it with a passion. If you don't believe me do a search on cast bullet forums. I'm far from the only one who's had problems.
