The Alpha brazing and soldering alloy powders can be supplied separately or as part of a braze paste. Atomised powders are produced to the standard size ranges, or to specific customer requirements.  Brazepates and solderpastes are manufactured by mixing the filler metal powder with an inert binder, which may also contain any necessary flux. Any alloy, which can be produced in powder form, can also be supplied as paste. Brazepastes and solderpastes can provide an easy and reliable method for preplacement of alloy in joining processes. They are particularly suited for automated production and furnace brazing.

PASTE PROCESS

Every Alpha paste is a combination of Brazing or Soldering Alloy powder with a specially formulated binder that may or may not contain flux. Whether for automatic Brazing or Soldering, or for hand application, each paste is customize to suit customer requirements. The Alpha paste process can help with improving quality, reducing rejects, increasing output and lowering unit costs.

The choice of a brazing alloy in paste form follows the same quidelines as the choice of alloy in solid form. Brazepaste is usually an individual product formulated for a specific application and here the experience of Metal Joining technical staff is used to select the correct particle, size, flux/binder system, viscosity and metal content.

PASTE BINDERS

The following binders are available :

METAL CONTENT OF PASES

* Metal contents can be varied to suit the requirements of the application.

VISCOSITY

Brazepastes and Solderpastes are formulated to give a range of viscosities, which allow easy dispensing. The viscosity of the paste can be altered to suit particular dispensing requirements.
