# ALU Gas Nozzle | \u00d8 1.2 mm | 10 pc Set<\/p>\n
This product is part of the Wiel\u00e4nder+Schill professional welding technology range, specifically optimized for aluminum MIG\/MAG welding processes, a high-quality consumable. An essential accessory for performing high-performance and reliable welding tasks, guaranteeing optimal current transfer and precise shielding gas flow.<\/p>\n
## Product Description and Application<\/p>\n
This high-precision contact tip (kontaktf\u00fav\u00f3ka) is made for aluminum welding and manufactured from **CuCrZr (Copper-Chromium-Zirconium)** alloy. This material features excellent thermal conductivity and high wear resistance, which is critical for minimizing high thermal load and rapid wear during aluminum welding.<\/p>\n
The nozzle is specifically designed and compatible with **SBT 307 G type welding torches**. The 1.2 mm bore diameter is ideal for the precise welding of thin and medium-thick aluminum sheets, ensuring a stable arc and adequate shielding gas supply.<\/p>\n
The product is supplied in a 10-piece set, ensuring long-term, uninterrupted work performance in the workshop.<\/p>\n

## Advantages of CuCrZr Material in Aluminum Welding<\/p>\n
Aluminum welding presents unique challenges, primarily due to high thermal conductivity and rapid electrode wear. Compared to traditional copper alloys, contact tips made from CuCrZr (Copper-Chromium-Zirconium) offer significant advantages:<\/p>\n
1. **Heat Resistance and Conductivity:** The CuCrZr alloy excellently conducts heat away from the torch body during welding, preventing premature softening and deformation of the nozzle. This makes the arc more stable.
\n2. **Wear Resistance:** The added chromium and zirconium increase the material's hardness and resistance to erosion caused by spatter and molten metal blowback. This results in a longer service life, reducing maintenance and replacement intervals.
\n3. **Arc Stability:** The clean, precise bore size (1.2 mm) ensures an even and laminar flow of shielding gas (usually argon) around the welding zone, which is essential for achieving high-quality, porosity-free aluminum joints.<\/p>\n
## Compatibility and Integration<\/p>\n
This nozzle is an integral part of the Wiel\u00e4nder+Schill welding technology systems. The perfect fit for the **SBT 307 G** torch guarantees quick and easy replacement, as well as maximum safety during operation. The standard **M8 x 27 mm** thread length ensures reliable fastening in the torch, preventing loosening or overheating along the thread.<\/p>\n
Use with a 1.2 mm wire diameter allows for optimal flow rate, which is particularly important when welding thinner aluminum profiles where excessive heat input can easily lead to burn-through.<\/p>\n
## Quality Assurance<\/p>\n
Wiel\u00e4nder+Schill products comply with the highest industrial standards. Manufacturing processes are accompanied by strict quality control, ensuring that every single contact tip meets the specified precision requirements. The company holds ISO 9001 (Quality Management) and ISO 14001 (Environmental Management) certifications, reflecting its commitment to product quality and sustainable manufacturing practices.<\/p>\n
