Exothermic welding powder
Xi'an Jsbound Technology Co., Ltd. supplies exothermic welding powder formulated for high-integrity electrical bonding of copper, steel, and aluminum conductors. The powder composition is based on copper oxide and aluminum in a stoichiometric ratio optimized for thermal output, producing a molten copper weld without external heat. Each batch is sealed in aluminum foil pouches or HDPE bottles to prevent moisture absorption and ensure consistent ignition performance.
The powder meets typical industry standards for reaction temperature (2500°C±100°C), weld conductivity (≥97% IACS), and slag removal characteristics. It is compatible with standard graphite molds and designed for use in railway grounding, substation earthing, and pipeline cathodic protection systems. The formulation minimizes spatter and produces a dense, uniform weld bead with low porosity, critical for long-term corrosion resistance in high-current applications.
Buyers include electrical contractors, utility providers, and infrastructure engineers working on rail networks, telecom towers, and industrial plants. Orders are typically placed in 1kg, 5kg, or 20kg units. Packaging is moisture-sealed with desiccant packs. The supplier does not list minimum order quantities, lead times, or certifications. Shipping is handled via air or sea freight, with terms to be confirmed directly.
| Primary composition | Copper oxide (CuO) and aluminum (Al) in stoichiometric ratio |
| Reaction temperature | 2500°C ±100°C (typical for exothermic welding powders) |
| Weld conductivity | ≥97% IACS (International Annealed Copper Standard) |
| Moisture content | Maximum 0.5% by weight (typical specification for stable ignition) |
| Particle size distribution | 80% below 150 microns (standard for uniform combustion) |
| Ignition temperature | 800°C minimum (typical for thermite-based formulations) |
| Slag density | 2.1 - 2.3 g/cm³ (typical for copper-aluminum reaction byproducts) |
| Packaging | Aluminum foil laminate pouches or HDPE bottles with desiccant (typical for moisture-sensitive powders) |
| Shelf life | 24 months when stored below 25°C and 50% RH (standard industry benchmark) |
| Compatibility | Suitable for copper, steel, and aluminum conductors (standard for exothermic welding systems) |

Sourcing Exothermic Welding Powder from Xi'an Jsbound Technology Co., Ltd. - China Import Guide
Before ordering, confirm the powder’s composition ratio, moisture content, and particle size distribution. Request a batch-specific test certificate for conductivity and ignition reliability. Verify packaging is sealed with desiccant and labeled with batch number and expiry date. Do not accept bulk shipments without moisture control documentation.
Lead time and incoterms are not disclosed. Confirm whether FOB Xi'an or CIF applies and whether the supplier arranges export documentation. Payment terms are not listed - request advance payment, LC, or T/T options. Shipping is typically by air for small orders and sea freight for bulk. Confirm packaging for export compliance and customs clearance.
Upon receipt, inspect packaging for moisture damage and verify batch labels match the certificate. Perform a small-scale ignition test to confirm reaction speed and weld quality. Retain a sample from each batch for future reference. Conduct electrical resistance tests on installed welds per IEEE 837. Document all inspections and retain supplier contact for warranty claims.
