High quality industrial thermic composition specially blended for industrial applicatioins to cut thick, heavy metals. This is the one used to weld railroad rails together. It too produces molten slag alloys (in larger volume) and extreme heat in excess of 4500º F to weld metals together or cut through it like a cutting torch. The military uses thermite to destroy equipment, documents and other incendiary uses as well as remote welding. Normally difficult to ignite, it can be easily ignited using our THERMITE IGNITION COMPOSITION listed above. Easily cuts through 1/4" steel in seconds - heavier metals slightly longer depending on thickness. Virtually dozens of uses for camping and survival in any weather or climate. Comes with instructions. Non-Hazmat Shipping By US Mail - No ATFE required to order.
