PASTE BRAZING ALLOYS

In addition to alloys in solid form, we also offer paste brazing alloys.

Brazing paste is a blend of metal brazing alloy powder,
flux and binder that comes in a homogenized, ready-to-use mixture.
Polymers and additives stop the liquid part separating from the solid part
and give the brazing paste its fluid properties.

Pastes can be applied using different methods:

syringed

screen-printing

by roller

sprayed

We can offer pastes tailored to suit the application method due to be employed.
We have an extensive range of binders and brazing pastes
for developing products that can be adapted to suit different processes.

Brazing pastes are particularly suitable for automated applications
as they are easy to integrate into the production process.

They are versatile for both large-scale application and detail work, enabling pinpoint use.

Applications:

Heat exchangers, heating elements,
fashion accessories, costume jewellery, fine jewellery

NICKEL-BASED BRAZING PASTES

With their innovative composition,
our Nickel-based brazing pastes lend themselves to application using any of the possible methods:
screen-printing
spraying
dipping
roller coating
using dispensers
syringing.
Nickel-based brazing pastes are mainly used in the production
of heat exchangers (EGR coolers) in the automotive industry.

SILVER-BASED BRAZING PASTES

Silver-based brazing pastes can be used in the brazing of:

steel, copper and its alloys, or nickel and its alloys.

They can be distributed using automated systems or by means of the screen-printing process.

When it comes to stainless steel brazing, zinc-containing pastes can result in corrosion issues,
and hence we recommend using a zinc-free alloy.

Silver-based brazing pastes usually contain flux and are thus ready to use.

Nonetheless, we can also supply pastes without flux to cater to specific needs.
