ZTW100B is an sponge iron powder containing 1% boron. Its high purity, consistent chemical composition, and well-controlled particle size distribution make it an excellent choice for use in flux-cored wires.
The precisely engineered 1% boron content ensures a uniform and segregation-free incorporation of boron into the wire core, leading to an even distribution throughout the weld metal. This is a key factor in achieving stable and reliable mechanical properties in the final weld.
Moreover, ZTW100B demonstrates significantly lower moisture absorption compared to traditional ferroboron materials, contributing to improved welding performance, better arc stability, and enhanced weld integrity.
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
