  • Sciencemadness Discussion Board - brittle aluminum alloys ...

    1:1 Mg:Al alloy aka magnalium 50 is brittle and Ga can make Al brittle over time but is there like 90% or higher Al alloys that are brittle so it can made in to fine powder using a ball mill faster. some times I can find Al metal swarf that are kind of brittle but not always. so I'm thinking making a very brittle alloy and crushing it then ball ...

  • Magnalium - Wikipedia

    Magnalium powder also burns with a crackling sound if burnt by itself, and provides a good compromise between the reactivity of magnesium, and the stability of aluminium. Another benefit for pyrotechnics is the brittleness of the alloy, as mentioned before. It is easily broken with a hammer and then ground in a coffee grinder to usable powder.

    The present investigation is to study the effect of Nano-fuel additives [Magnalium (Al-Mg) and cobalt oxide (Co3O4)] on the performance and emission characteristics of Jatropha biodiesel (B100) in a single cylinder, air cooled, direct injection diesel engine. Ball mill (Magnalium) and Sol-Gel (Cobalt oxide) processes were adopted for Nano-particle preparation.

    When magnalium is used, particle size specs are often explicitly given. Avoid ball-milling glitter compositions! Many experienced pyrotechnicians have pointed out that ball milling can have a detrimental impact on the performance and appearance of glitter stars, a fact that is mentioned even by Ronald Lancaster.

    Nice tutorial. Milling time varies though and is dependent on several factors. I have a homemade ball mill that uses a 1/2 hp induction motor and 4" PVC sewer pipe as a drum. It can mill 1/2 pound or so of aluminum sandings down to powder, that works well in small salutes mixed with KClO4 or KClO3, in about 2 days.

  • Sanding Magnesium - narkive

    I would like to use Magnalium, but I am stuck with either KNO3 or sulfur (yes I know, sulfur) as the oxidizer, so I want to use the most energetic fuel possible. The last time I made Mg/S flash I used the powder made with my ball mill and 95% garden sulfur that was already finely powdered. I placed a gram on a piece of particle board, and lit

  • Magnalium - Hyperleap

    Magnalium is an aluminium alloy with 5% magnesium and 95% aluminum. The metal is now obtained mainly by electrolysis of magnesium salts obtained from brine, and is used primarily as a component in aluminium-magnesium alloys, sometimes called magnalium or magnelium.

  • which alloy is used for making ball mill

    Ball milling technique, using mechanical alloying and mechanical milling approaches were proposed to the word wide in the 8th decade of the last century for preparing a wide spectrum of powder materials and their alloys. In fact, ball milling process is not new and dates back to more than 150 years.

  • Alan Yates' Laboratory - Comments for "Making Magnalium"

    A hammer mill could be constructed to do all the hard work, bit it would be quite noisy. I've managed to make small amounts of ultra-fine Magnalium powder by ball milling granular material with commercial Aluminina deburring media designed for lapidary use.

  • Powder metallurgy – basics & applications

    In dry milling, about 25 vol% of powder is added along with about 1 wt% of a lubricant such as stearic or oleic acid. For wet milling, 30-40 vol% of powder with 1 wt% of dispersing agent such as water, alcohol or hexane is employed. • Optimum diameter of the mill for grinding powders is about 250 mm Ball Mill

  • Sciencemadness Discussion Board - Ideas for fine Al and Mg ...

    Ball milled magnalium could be a totally different story though, because this would make a much finer powder than what could ever be obtained from Mg or Al. I put some of the magnalium powder into water and added some NaOH to dissolve the Al and leave behind ultrafine atomized Mg.

    I prepare the Magnalium by ball milling -20 mesh granular material with commercial triangular Aluminia deburring media. It takes about 3 days for produce a dark grey powder that feels only ever so slightly gritty between the finger nails. About 200 mg of this composition will produce a loud pop when ignited on a tile with blackmatch.

    Changing the mixture to 67/33 for a more OB mixture extremely weakens the FP. Changing the mixture to 72/28, may strengthen it. Flash had nearly the same brisance as SADS, the same dent and number of fragments, however it did not have the same sand indent depth. This explains why ammonal can be detonated by good flash.

    The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

    Face milling however, can be carried out at speeds up 3000 m/min (10000 ft/min) with feed rates between 0.05 and 0.5 mm/tooth. Depths of cut can be up to 12 mm. It should be noted that certain drilling, reaming and tapping operations are unsuitable for high speed machining. Coarse feed rates should be employed in order
