Thermite Powder/Thermite Welding Powder
It is thermal welding supplies. A prepared package containing the correct quantity of Thermite Welding Powder for the type of weld to be made. Thermite powder is a pyrotechnic composition usually consisting of metal powder and metal oxide. Thermite welding powder is not usually explosive, but it does create extremely high temperatures in a very small area for a short period.
The price list for any quantity of Thermite Powder is available within 12 hours!
The thermite reaction is a reaction in which aluminum metal is oxidized by an oxide of another metal (the most common is iron oxide).Most importantly, this process produces molecular joints, not just mechanical joints between conductors. It is produced by an initial reactant, which provides enough energy to activate the welding reaction. This is done quickly and safely in the sand mould. Depending on the components to be welded and the type of joints required, the Sand Mould is specifically designed for a certain joint.
Thermite powder / Thermite welding powder
Thermite powder is a pyrotechnic composition usually consisting of metal powder and a metal oxide. Thermite welding powder is not usually explosive, but it does create extremely high temperatures in a very small area for a short period of time. For instance, aluminum/iron-oxide thermite temperatures are as high as 4500 degrees F.
Thermite welding for railroads offers several advantages, including: a reliable heat source and easy-to-use equipment, requiring fewer workers. Additionally, this method produces smoother results compared to gas pressure welding. The steel rails are held securely in place during the welding process, ensuring a smooth finish based on the fixtures used. This type of welding is ideal for seamless tracks that don't require longitudinal movement. As it involves a casting process, the resulting joint has a cast-like structure.

Thermite Welding Powder Chemical Properties
| Chemical nature | 98.00% |
| Synonym | Thermite Welding Powder, Thermite Powder, Thermite Reaction, Gold Schmidt Reaction, Sodium, Thermite Welding Powder, Thermite, Thermite Welding, Copper Thermite, Cadwelding |
| Precautions | Main material are mixture of iron oxide powder, aluminum powder and steel alloy. It should be protected from water, moisture and broken. |
| Reactivity: | *Fe2O3 + 2Al ==> 2Fe + Al2O3 + heat |
| The product is alumina, free element iron, and a lot of heat. The reactants are usually powdered and mixed with a binder to keep the material solid and prevent separation. | |
| Other metal oxides, such as chromium oxide, can be used to generate elemental metals. | |
| Copper thermite uses copper oxide to create electrical joints in a process called cadwelding: | *3CuO + 2Al ==> 3Cu + Al2O3 + heat |
| Chemical name | Thermite reaction |
| Chemical formula: | 1) Fe2O3 + 2Al ==> 2Fe + Al2O3 + heat |
| 2) Aluminum + iron oxide (III) ==> iron + alumina 2Al(s) + Fe2O3(s) ==> Al2O3(s) + 2Fe(s). |

Thermite Welding Powder Typical Application
Thermite has many uses. Originally used for on-site repair welding of locomotive axle brackets, etc., it can be repaired without removing the parts from the installation position.
Thermite can also be used to quickly cut or weld metals such as railroad tracks without the need for complex or heavy equipment.
Currently, Thermite Powder is widely used in welding, metal cutting or drilling, on-site emergency metal repair, scientific demonstrations, high-temperature ignition, prohibited military equipment (including artillery, documents, and hard drives), and other applications.
Steel rail aluminum heat welding flux is mainly used in railroad line maintenance, line overhaul, and new line construction.
Use scenarios: such as railroads, subways, factories' lifting rails, elevated railroads, city rails, etc.
Characteristics of Thermite Powder
1. It has superior conductivity to the conductor itself.
2. Will not corrode, oxidize or degrade over time, and can resist galvanic coupling.
3. Able to withstand repeated discharges.
4. It will never increase its resistance.
5. It has greater mechanical and squeeze resistance than the conductor itself.

Precautions for Using Thermite Powder
1. Don't try to ignite Thermite Powder by immersing the fireworks in the mixture by hand. This mixture will and does burn violently and will spray burning metal at you.
2. The violent ignition of Thermite Powder will spray molten metal in all directions. When the mixture is on fire or burning, do not approach it.
3. If you cannot ignite the thermite with fireworks, try mixing some magnesium powder or magnesium flakes into a small amount of Thermite Powder mixture. Then you should be able to use your pyrotechnics to ignite the magnesium mixture.
4. Thermite Welding Powder burns very hot and produces molten iron slag that can be melted through the car engine block! Burning Thermite Welding Powder can splash molten iron over a long distance from the burning pile. Keep as far away as possible. And make sure that there is nothing nearby that could catch fire. First start the thermite experiment with a small amount until you understand its behavior and how far it throws molten metal slag.
5. Do not use water to extinguish the thermite fire. Do not try to extinguish the fire with water, otherwise a violent steam explosion may occur, which will also cause slag. Similarly, do not use any wet materials to try to extinguish the fire.
