Product Introduction

Product Description

 

Silver-based solder is a medium-to-high-temperature brazing material, primarily composed of elements such as silver, copper, and zinc in varying proportions. Some grades can incorporate additives like tin and nickel to enhance process performance. Based on their melting points, silver solder is classified into low-temperature, medium-temperature, and high-temperature types, each suitable for different materials and operating conditions. The product exhibits excellent wetting and fluidity properties, utilizing capillary action to fill gaps and form dense, high-strength, and corrosion-resistant solder joints that maintain stable performance under harsh conditions such as high temperatures, high pressures, and vibrations.
