LAP40.37 is a high density water atomized iron powder with low carbon and oxygen content, and it exhibits high consistency in chemical composition and particle size distribution. These characteristics give it exceptional purity and performance stability.
This powder is particularly suitable for applications requiring high purity and excellent welding performance, such as alkaline coated electrodes, flux-cored wires, and metal-cored wires. Its high density not only enhances the overall performance of the filler materials but also significantly improves the stability and efficiency of the welding process.
With its outstanding purity and uniform physical properties, LAP40.37 provides reliable support in various high-performance welding applications, making it an ideal choice for enhancing welding quality and production efficiency.
Powder grades for welding applications:
As a key component in the production of a wide range of welding consumables, the characteristics of iron powders often have a direct influence on both welding properties and final weld metal quality. Our sponge and atomized gradesare distinguished by particle size distribution, chemical composition, particle morphology and apparent density. Choosing iron powders with suitable characteristics for a given application will result in enhanced efficiency and overall welding performance.
Benefits:
• Wide range of iron powders developed for welding applications
• Narrow specifications
• Consistent chemical and physical properties
• Low level of impurities
• Efficient logistics solutions and smart packaging
