Pure Core – Aqualine 6000 & AS2
Rosin-Free Water Soluble

ALPHA® Pure Core

ALPHA Pure Core is an organic activated, water soluble flux cored solder that meets the Corrosion Resistance Test and Surface Insulation Resistance requirements per IPC-TM-650 ALPHA Pure Core contains a water soluble resin derivative of rosin and a buffered organic activation system. This efficient flux produces bright, shiny solder connections, even if cleaning is delayed for several days.

Features & Benefits

ALPHA Pure Core is recommended for use in any electronic hand soldering application where high fluxing strength and the ability to clean with water are desired. It has low smoke and odor characteristics which make it particularly suited for touch-up and repair of printed circuit boards where personnel are in close contact with the product.

The very effective activator system enables the flux to penetrate even heavily tarnished surfaces among the following materials:

  • Beryllium Copper
  • Copper
  • Solder (Plate)
  • Brass
  • Lead
  • Solder (Hot Dip)
  • Bronze
  • Nickel (Plate)
  • Terne (Plate)
  • Cadmium (Plate)
  • Silver
  • Tin (Hot Dip)
  • Tin (Plate)


ALPHA AQUALINE 6000 is a QPL-approved (Type WSF-0 polyglycol-free flux), halide-free, water soluble flux cored solder. Its post soldering residues are extremely water soluble and can be easily cleaned with hot water. Due to the exceptional wetting and cleaning characteristics of ALPHA Aqualine 6000, it is recommended for use in a broad range of applications, including both commercial and military.

Features & Benefits

  • Excellent wetting characteristics. Ease of solderability.
  • Extremely cleanable post-soldering residues. High ionic cleanliness and long-term reliability.
  • Halide-free. High reliability assemblies.
  • QPL-Approved per QQ-S-571, Type WSF-0. Provides military assemblers the option to use a water soluble process.


ALPHA AS2 is a rosin-free activated cored solder wire. Its flux formation is based on volatile organic compounds with an extremely effective activator system. Alpha AS2 is particularly formulated for flame soldering, for example with bulb production and capacitor manufacturing. However AS2 can be used with any other soldering technique if temperature is high enough and sufficient heat applied and SIR of flux residues is not a premium requirement.

Features & Benefits

ALPHA AS2 flux is considered to be conditional corrosive and decomposition starts at 135°C. With continued heating the flux nearly completely evaporates. AS2 is not flammable and provides very smooth solder flow until volatilised. These properties are especially suited for flame soldering in bulb industries and capacitor production, but also for other applications, where activity of rosin flux is not sufficient.
