Brazing pastes which are often also called soldering pastes are a homogenous mixture of brazing alloy powder with a binder and, in certain cases with a flux, depending on the heating technique. The alloy powder has the function of melting at the desired temperature, filling the gap by capillarity, and assuring the joint strenght after solidification. The binder shall assure easy and consistant dispensing and decompose upon heating without leaving residues. A flux is added when the parts to be brazed are heavily oxidized or when heating is done in air.
The exact quantity of brazing paste required is deposited on the cold parts to be joined. They are then heated either by torch in air, in a belt furnace under protective atmosphere or by an other heating method.
All brazing pastes are custom made to suit ideally the customers parts and process.
Advantages
The advantages of using brazing pastes instead of conventional techniques are the following:
- Improved production rate (time savings)
- Very precise deposit of brazing alloy (material savings)
- Brazing alloy and flux deposition in one step
- Easy to use
- The process can easily be automized
The brazing paste identification is composed of the following components:
| Example of CF 18KYES2 H722E-0 | |||
|---|---|---|---|
| CF 18KYES2 | H722 | E | -0 |
| Brazing alloy designation | Binder or flux-binder designation | Alloy Powder Content | Powder Particle Size |
| (according to the brazing alloy list) | (suggested by the Hilderbrand specialists according to the customers need) | The most common are E = 65% J = 78% T = 91% W = 94% |
The most common are -2 = 106micron max. -1 = 75micron max. -0 = 45 micron max. |
Packaging
The brazing pastes are generally packed in 3, 10 or 30cc syringes ready for use. Upon customer request, packaging in bulk is also available.
Health and Safety
The health and safety of the user of our brazing pastes is always in
the centre of our attention. Toxic or harmful materials are avoided wherever
possible. Practically all our brazing pastes are cadmium free. The alloy
designations starting with "CF" in the Dental Brazing Paste
list are cadmium free.
