HILDERBRAND 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 strength after solidification. The binder assures easy and consistent dispensing and decomposes upon heating without leaving a residue. 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 (argon, hydrogen, cracked ammonia) or by any other heating method.

The advantages of using brazing pastes instead of conventional techniques are the following:

• Improved production rate (time saving)
• 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
• Focus on health and safety of users
