4145 Aluminum
AMS 4184, AWS A5.10
4145 aluminum welding wire is a specialized alloy utilized for welding and brazing applications, particularly in the aerospace industry. Its chemical composition is significant due to the inclusion of 5% magnesium, which enhances strength and corrosion resistance, while the addition of silicon helps improve fluidity during the welding process, resulting in smoother, more precise welds. This alloy's low melting temperature, typically around 565°C (1050°F), makes it well-suited for brazing applications where precise, lower-temperature joining is essential, all while maintaining high strength and corrosion resistance. Specifications*: AWS A5.10, Class ER4145 AMS 4184 ISO 18273, AlSi10Cu4 * Specifications may vary per heat.Please inquire with your specification before purchasing.

C355 (4009) Aluminum
AMS 4245, AWS A5.10
C355 aluminum welding wire, as well as the variant 4009, is a versatile welding material primarily used for joining aluminum and aluminum alloys. It typically consists of approximately 90% aluminum (Al), 4% silicon (Si), 1% manganese (Mn), 1% copper (Cu), and trace amounts of other elements such as zinc (Zn) and titanium (Ti). This specific chemistry is carefully formulated to provide the wire with excellent weldability and mechanical properties making it suitable for a wide range of applications, from automotive components to aerospace structures. The silicon content enhances the fluidity of the molten metal during welding, promoting a smoother and more stable weld bead. The manganese and copper additives contribute to the wire's strength and enables the weld to respond to heat-treating. Specifications*: AWS A5.10, Class R-C355.0 AWS A5.10, Class ER4009 AMS 4245 ISO 18273, AlSi5Cu1Mg * Specifications may vary per heat.Please inquire with your specification before purchasing.

Safety

HQA Wire Products strongly recommends exercising safe welding practices to protect yourself and others. Electric shock can be dangerous and can kill. Fumes and gases can be dangerous to your health. Arc rays can injure eyes and burn skin.

Safe Welding Practice include but are not limited to:

  • Do not permit electrically live parts or electrodes to contact skin.
  • Do not allow contact with clothing or gloves if they are wet.
  • Insulate yourself from work and ground.
  • Keep fumes and gases from your breathing zone and general area.
  • Keep your head out of fumes.
  • Use enough ventilation for exhaust and arc or both.
  • Wear adequate eye, ear, and bodily protection.
