The silver strip for welding is a high quality welding material in the form of strips, mainly composed of silver and other alloys. The purpose of this strip is to enable effective and precision welding operations, which are characterized by increased conductivity and resistance to corrosion. The Silver Soldering exhibits fine technological properties as well as low melting point, excellent wettability and gap-filling ability, high strength, fine plasticity, electrical conductivity and excellent resistance to corrosion. It can be used for brazing aluminum and magnesium. It has a wide range of applications including all ferrous metals as well as non-ferrous metals except for the rest of the low-melting-point metals. The solder presents itself in form of strips, ribbons, wires rims pastes etc., beside preforms “composite” products or flux-cored wire series. And it can work together with personalized research development on new formulas.

Brazing Silver Solder is a process of joining metals using a silver-based alloy as the filler material. It requires heating the metals to a temperature above 450°C (840°F) but below their melting points.
Silver Solder is versatile and can be used to join a variety of metals, including copper, brass, steel, stainless steel, and more.
The melting point of Silver Solder varies depending on the specific alloy, but it typically ranges between 600°C to 800°C (1112°F to 1472°F).
Silver Solder provides strong and durable joints. It has good thermal and electrical conductivity, making it suitable for various applications, including electronics and plumbing.
Brazing involves higher temperatures and the use of a filler metal with a higher melting point compared to traditional soldering. It results in stronger and more heat-resistant joints.
Yes, Silver Solder is commonly used in jewelry making to join silver and other precious metals. It allows for precise and aesthetically pleasing joints.
Adequate ventilation is essential when using Silver Solder, as the process may release fumes. Protective gear such as gloves and safety glasses should be worn, and proper heating equipment must be used.
While Silver Solder joints are strong, they can be disassembled using heat. The joint needs to be heated to the melting point of the solder to separate the parts.
Yes, flux is typically used in Silver Soldering to prevent oxidation and promote the flow of the solder. It helps ensure a clean and strong joint.
Yes, Silver Solder is suitable for high-temperature applications due to its relatively high melting point. It is commonly used in situations where other solders may not withstand the heat.
