Check out the products available and order the soldering filler you need online - conveniently and at a great price.

Soldering binders - applications and types

Solder filler metal is a metal alloy used in the soldering process. It acts as an adhesive. It allows you to create a durable, durable and flexible connection of metal elements without interfering with their condition. Solder in its traditional form is a mixture of tin and lead. In turn, lead-free solder consists mainly of tin (97%) and copper. Leaded solder continues to be very popular due to its lower melting point, softness and efficiency. However, lead-free solder is considered much safer for the user, but also more difficult to use and less efficient. The product is heated by a soldering iron. In its liquid state, it precisely fits the element, filling the space. There are different ways of soldering. Due to the range of melting temperatures and the binder used, soft soldering and hard soldering can be distinguished.

Soft soldering

In soft soldering, the temperature needed to effectively bond materials does not exceed 400-450oC (which is relatively low). The binder may be in the form of wire or sticks. It is a mixture of tin and copper or tin and lead. Soft soldering is used primarily when connecting electronic components and parts of sanitary and heating installations, as long as the operating temperature does not exceed 110o C.

Hard soldering

In brazing, the melting temperature of the binder exceeds 450o C. Hard solders are characterized by maximum resistance to mechanical damage, stretching and extreme temperatures. The hard binders used in this soldering method are silver, phosphorus and copper solders. In the brazing process, the following are connected, among others: steel, copper, precious metal, brass and bronze elements. Brazing will be used primarily in heating, oil, refrigeration and air-conditioning installations and wherever the operating temperature is very high (exceeds 110o C).
