We offer refrigeration solders from the brands Armack and Stella. These include copper-phosphorus hard solders in the form of 500 mm rods (uncovered) and solders with a high silver content in the coating. Our solders are manufactured from pure raw materials, ensuring high quality and consistent chemical composition. In our standard range, we have the following hard solders: CuP6, Ag2CuP, Ag5CuP, Ag34Sn, Ag45Sn. The complete range of refrigeration solders is available for individual customer orders.

 

CuP6 Solder

Used for hard soldering copper to copper (without the use of flux). Applied for soldering copper joints in hot and cold water installations as well as central heating systems. Does not contain iron and nickel, making it suitable for the electrical industry in devices where the operating temperature does not exceed 200°C.

Specifications:

  • Solder according to DIN EN 1044-CP203
  • Melting temperature range: 710 – 880°C
  • Operating temperature: 760°C
  • Dimensions: 2.0 x 500 mm
  • PZH Certificate

Ag34Sn Solder

Used for soldering steel and copper materials with connectors made of steel, copper, brass, and copper-zinc alloys. Applied for joining installations for cold and hot water, oil, liquid gas, city and natural gas, as well as those transmitting fluorinated hydrocarbons.

Specifications:

  • Solder according to DIN EN 1044-AG106
  • Melting temperature range: 630 – 730°C
  • Operating temperature: 710°C
  • Dimensions:
    • 2.0 x 500 mm
    • 2.0 x 500 mm (coated)
  • PZH Certificate

Ag45Sn Solder

Used for soldering steel and copper materials as well as joining these materials together. Applied for joining installations for cold and hot water, oil, liquid gas, city and natural gas, as well as those transmitting fluorinated hydrocarbons.
