1 LB Magnalium MG/AL -325 Mesh

Magnalium is a blend of magnesium and aluminum, typically used in fine powder form, finer than 120 mesh for spark effects and strobe stars, and between 30 and 50 mesh for crackling microstars. It is more powerful than aluminum powder of similar mesh size and is highly reactive.

Magnalium is primarily used in fireworks to create spark effects, enhance other stars, and produce crackling effects. It can be substituted for aluminum powder in various mixtures, including thermite and flash powder, but precautions must be taken due to its reactivity.

The use of magnalium in fireworks offers several benefits, including its ability to produce bright spark effects, enhance the visual appeal of stars, and provide a unique crackling effect. It is a versatile ingredient that can be used in a variety of compositions to achieve desired pyrotechnic effects.

When using magnalium in fireworks compositions, it is important to follow specific application techniques. Proper mesh size selection and blending with other ingredients are crucial for achieving the desired effects. Additionally, precautions should be taken to prevent spontaneous ignition, especially when in contact with nitrates or ammonium perchlorate.

Magnalium has minimal environmental impact when used in fireworks compositions. However, proper disposal practices should be followed to prevent contamination of the environment.

When handling magnalium, it is important to wear a dust mask to protect against harmful dust. Mixtures containing nitrates or ammonium perchlorate and magnalium should be handled with caution, as they may ignite spontaneously, especially when moist. Coating with linseed oil or treating with potassium dichromate can help prevent these reactions.

Store magnalium in a cool, dry place away from moisture and incompatible compounds. Proper labeling and secure storage containers are essential to prevent accidents and ensure product integrity.
