#FLUX PASTE SERIES#

It solders at temperatures under 200☌, thus protecting copper piping built into the heat sink. Superior AL26-193-75 is blended with a proprietary low-melting solder alloy that is specifically formulated for the direct soldering of heat sinks. Superior AL26-33-75 solder paste residues are water soluble and must be washed off after soldering. The aluminum solder paste creates a true inter-metallic bond between the solder and aluminum substrate. Superior AL26-33-75 direct aluminum solder paste combines aluminum flux and tin-silver solder powder to create an all-in-one aluminum soldering solution, ideal for applications where precision dispensing is required This water-soluble aluminum solder paste was designed for aluminum to copper soldering. Soldering Aluminum (SME International Brazing & Soldering Conference – Orlando, FL, 2009) Here are a few papers on aluminum soldering, written by our aluminum soldering expert:ĭirect Aluminum Solder Paste (IMAP Thermal Management Workshop – Palo Alto, CA, 2011) To see some of our products in action, see the Video Links for aluminum soldering applications. In addition to these flux products, Superior Flux offers a non-hazardous aluminum cleaner, which can be used both pre- and post-solder.Īn in-depth explanation and introduction to our most popular aluminum soldering products can be found in our Aluminum Soldering Product Guide.

They include direct aluminum solder paste and direct aluminum tinning paste.

The concentration and composition of both the flux and the alloying metal depend greatly on the form and series of aluminum to be soldered.ĭepending on your application, there are several ways to incorporate aluminum pastes into your process. Superior Flux offers the widest range of aluminum solder pastes on the market, including fluxes for soldering aluminum-to-aluminum, aluminum-to-copper, aluminum-to –brass and aluminum-to-plated terminals. Aluminum and its alloys are notoriously difficult to solder due to their ability to rapidly form a protective and tenacious surface oxide layer.
