Solders & fluxes

Soldering is a process in which metal parts are joined with an additional material (solder) whose melting temperature is lower than the melting temperature of the metals to be joined. A solid metallurgical bond is created by the connection between the filler metal and the metals to be joined. A distinction is made between brazing, in which the melting temperature of the filler metal is below 450°C, and hard soldering, in which the melting temperature is above 45°C. Physical and chemical phenomena such as capillarity occur during brazing. Castolin Eutectic's wide range of filler alloys and fluxes offers you a solution for all brazing applications.
Solders and fluxes are important materials for a variety of industrial and electronic applications. Solder is a metal alloy used to join two metal parts. Flux is a chemical that helps clean the metal surfaces and prevents oxidation.

There are many different types of solder, each with its own unique properties. The most common type of solder is tin-lead solder, a mixture of tin and lead. Tin-lead solder is easy to work with and has a low melting point, making it suitable for a variety of applications. Other types of solder include silver solder, which is used for high-temperature applications, and copper solder, which is used for electrical applications.

There are also many different types of flux, each with their own unique properties. The most common flux is rosin, a type of organic flux made from tree resin. Rosin fluxes are easy to use and create a strong bond. Other fluxes include acid fluxes, which are made from acids, and water-soluble fluxes, which are made from water-soluble solvents.

Solders and fluxes are used in a variety of industrial and electronic applications, such as plumbing, heating and cooling, and construction
Solders and fluxes offer a number of advantages, including ease of use, low melting point, strong bond, wide range of applications

When selecting solder and flux, it is important to consider the following factors:

• The type of metal to be joined
• The temperature range
• The desired properties of the joint

When using solder and flux, it is important to use the correct type of solder and flux for the application and to have a clean work surface. Follow the manufacturer's instructions carefully, wear safety goggles and gloves and dispose of solder and flux properly.
