Soft solders

Brazing is a process in which a joint is created between metal parts by melting a soft solder between the parts. The parts are not melted, but the solder between them melts and forms a solid joint. Soldering is an ideal technique for joining metals that cannot be welded due to their high melting temperatures.

Castolin Eutectic offers an extensive range of high-quality soft solders for soldering applications. Our soft solders allow you to create a reliable and strong bond between different metals and are specially designed for strong joints. The use of soft solders offers a cost-effective and reliable alternative to welding as they do not require high temperatures and do not cause deformation or discoloration of the materials.
Soft solders are alloys of lead and tin that are used to join two metal parts. They have a low melting point and are therefore suitable for a wide range of applications, e.g. electrical connections, plumbing and jewelry making.

There are many different types of soft solder, each with their own properties: Cadmium-free tin-silver based soft solder, Silver solder: consists of a mixture of silver, copper and other metals and is used for high temperature applications, Copper solder (made from a mixture of copper, tin and other metals).

When are soft solders used?

Soft solders are used in a variety of applications, e.g. in the plumbing trade for joining pipes, in the building trade and in heating and cooling construction for joining pipes and fittings in heating and cooling systems.

Soft solders are easy to process with a soldering iron, have a low melting point and are therefore suitable for a wide range of applications and can create a strong connection between two metal parts.
When selecting soft solders, it is important to consider the type of metal to be joined, the temperature range and the desired properties of the joint.
