POS 40 and POS 61 solders https://ukrstarline.ua/en/non-ferrous-rolled-products-and-alloys/alloys/solder – these are tin-lead alloys to which copper and antimony are added. The grade determines the percentage of proportions. For example, POS 40 is when there is 40% tin and 60% lead, POS 61 – the proportions are the opposite. The main advantage of these grades is their versatility and the possibility of a wide range of use. They are reliable, highly effective when soldering any materials, due to which they are actively used in various industries.
Types of solder
This alloy is divided into several types, each with its own individual characteristics:
- Soft: This solder can withstand temperatures up to +300 degrees. It is applied using a soldering iron and is intended for soldering electrical components and wires.
- Hard: Solder is optimal for soldering copper parts, withstands temperatures above +300 degrees, applied using a gas torch.
- Low-melting: The alloy is used in repair work and the manufacture of equipment and radio components. It contains zinc, lead, tin, and bismuth.
- With flux: This solder is similar to wire, during soldering a flux begins to form, which provides a special protective layer.
- Refractory: This solder is distinguished by its industrial purpose, suitable for joining hard materials. The alloy contains a refractory substance, designed to join parts made of cast iron, brass, bronze, etc.
Taking into account the above criteria, you will be able to select a solder that meets your requirements and wishes.
The Benefits of Using Solder Today
Due to a number of advantages, solder is gaining more and more popularity and demand. The main advantages include the following:
- Strength of connections: Solder POS 40 and POS 60 have excellent mechanical properties, which ensures the reliability of any connections. This indicator is especially important in electronics, where all contacts must be reliable.
- Resistance to resolutions: These brands of solder significantly extend the service life of components due to their resistance to oxidation and corrosion processes.
- Easy to use: These brands are suitable not only for beginners due to their simplicity, but also for professionals due to the optimal melting temperature. Precise and clean seams ensure ease and simplicity of work with these solders.
- Wide application: The alloy is ideal for a variety of applications, from radio equipment to jewelry manufacturing.
Due to their positive characteristics, solders of the POS 40 and POS 61 brands are actively used in various industries. They are resistant to wear, moisture, corrosion, and aggressive environments. These alloys are durable, reliable, practical, strong, and can withstand increased loads, making parts resistant to mechanical damage.
How to choose the right solder
To select the most optimal solder, consider certain criteria regarding its selection:
- Release form: Standard solder is in the form of granules, paste, powder or wire. Granules and powders are optimal for production processes. Paste is a combined option, used when soldering materials with a low melting temperature. Wire is intended for complex tasks, boards and electronic systems.
- Melting temperature: The alloy can be low-melting or high-melting. It is advisable to choose the option that melts at a minimum temperature lower than that of the connecting parts.
- Flux supply: Self-fluxing solders are the easiest to use. They have a design with flux inside and solder on the outside. Flux-free alloy is optimal for inert gases, flux is applied separately to protect against oxide film (increases resistance to corrosion processes).
- Manufacturing technology: Ready-made solder is popular.
- Heat Resistance: Soldering is often used in the construction of furnaces and high-temperature objects. Opt for solders that contain niobium, zirconium, or tungsten.
Based on the above criteria, you will select the solder that is optimal for specific purposes. Choose based on your wishes, requirements, and quality standards.
Conclusion
Solders POS 40 and POS 61 are considered an important material intended for soldering various metal structures. A unique characteristic is the use in all industries (construction, metalworking, electronics, mechanical engineering, etc.). With the help of this alloy, the most reliable tools are manufactured, strong connections are created. When choosing a brand, consider the requirements of the project and the type of materials that need to be connected.
