Supplier's note

  1. Technical Breakthroughs:

    • Cobalt Alloy Core: With ErCoCr-A composition, welds retain structural integrity at 1,200°C—20% higher than standard electrodes.
    • Flux Coating: Reduces spatter by 30% compared to uncoated rods, improving workplace safety.
    • Diameter Flexibility: Three standardized sizes eliminate the need for custom rod selection in most industrial scenarios.

  2. Optimal Version Selection:

    • Base Model: Ideal for general workshops requiring cost-effective solutions (e.g., automotive repair shops).
    • Advanced Model: Suited for medium-scale fabrication (e.g., HVAC ductwork), with enhanced coating reducing downtime for cleanup.
    • Pro Model: Designed for heavy industries like aerospace or power plants, where ultra-high tensile strength and minimal spatter are critical.

With the Pro Model’s 800 MPa tensile strength, you can weld turbine components that withstand extreme thermal cycles. Pair its ultra-low-spatter coating with cobalt alloy durability to ensure zero defects in high-stakes applications.
