Technical characteristics of PSR 45 solder

One of the key materials used in the welding process is solder. It allows you to connect several metal parts to each other. Due to the fact that each individual metal or metal alloy has a certain set of properties that manifest themselves during the soldering process, it is necessary to select a solder for it that would correspond to these characteristics. Often, in order to improve soldering properties, fluxes and other additional substances are used together with solders to obtain a more reliable and high-quality connection.

Specifications

PSR 45 solder is a medium-melting material and is suitable for use at high temperatures

. Together with PSR 40, which is similar in composition, it belongs to the category of silver solders. The cost of this material due to the presence of expensive silver in it is quite high, however, this does not prevent it from being extremely in demand, since it provides durable, high-quality seams.

Another indisputable advantage of PSR 45 solder is the high level of ductility of the connection obtained with its help. The material also owes this quality to the silver present in its composition. After the seam has completely hardened, it becomes practically not subject to deformation. But even if this occurs as a result of significant mechanical impact from the outside, the joint is not destroyed due to the excellent ductility of the material. This feature allows the use of solder of this brand in mechanisms that are characterized by high mobility and a high probability of bending and other types of deformation at the seams.

PSR 45 brand solder is excellent for use not only in industrial conditions, but also at home, since a standard soldering iron is sufficient to work with it. It can be used both as the main consumable material for creating seams, and can be used in various tinning works, in particular all kinds of products made of copper and alloys based on it. The alloy combines especially well with copper-nickel compounds. In addition, PSR 45 can be used for soldering bronze, brass, nickel silver, nickel and other products. Sometimes it is even used when soldering thin silver elements in jewelry.

Of course, one of the main advantages of this solder is the minimal likelihood of defects occurring when working with it. It ensures the production of compounds that are unique in their quality and characteristics, and the final result practically does not depend on what type of metal the products are made from.

An important point is the resistance of solder to the destructive influence of aggressive environments, due to which it is actively used in the chemical industry

. The seams obtained with its help also withstand high temperatures, however, operation in conditions of extremely extreme temperatures is not recommended in order to avoid emergency situations.

Release forms

PSR 45 brand solder is produced in several versions, the most popular of which is wire. This format is very convenient for use both at home and in production. In this case, the material is supplied in coils containing a certain number of meters of wire. There is a wide variety of types of wire, differing from each other in diameter. Thanks to this, the most optimal version of this wire can be selected for each operation.

Silver solder of PSR 45 grade is also produced in sheet format. In this form, it is usually used in production, since using sheets at home is completely inconvenient. Sheets can have different thicknesses depending on the work they are intended for.

Another form of release is neat tubes, inside of which a certain amount of spruce rosin is placed. Thanks to this combination, it is possible not only to improve the characteristics and properties of the resulting compounds, but also to simplify the work, since only one is used instead of several materials.

Varieties

The most common type of solder is wire, as it is very convenient for home and factory use. The material is supplied in the form of a coil, where several meters of wire are wound. The wire can have different thicknesses, since different soldering modes should be used for each soldering condition.

Solder in the form of wire PSR 45

PSR 45 solder can be supplied in sheet form. This variety is more suitable for industrial use, since at home the sheets may not be wide enough and sometimes uncomfortable. The thickness is adjustable depending on the assortment, but in terms of storage this is a very suitable option

Sheet solder

Fluxed solder in the form of tubes. The tube contains spruce rosin, which helps improve soldering properties. This turns out to be very convenient because only one material is used, and not several, as happens in other cases.

Assortment

Explanation of markings

Each material that is created for soldering has its own unique marking. As a rule, the markings indicate the type of solder, as well as its composition. This helps to select the options required for soldering. Here it is worth noting such points as:

• PSR is a solder that contains silver. Here it acts as the main element that sets the properties of the alloy;
• 40 – silver content in percent. So it contains 40%.

Marking

Like other soldering materials, this solder has a unique marking that allows you to judge its type and components. Its name is deciphered as follows:

• PSR is a solder that contains silver. It is this element that is the main one in the composition and generally determines the properties of the alloy.
• 45 – this number indicates the quantity of the main element, that is, silver, contained in the solder. This brand includes 45 percent of the valuable element.
