Product Description
Silver blocks, silver bricks, silver ingots
Silver is commonly used to make highly sensitive physical instrument components, various automation devices, rockets, submarines, computers, nuclear devices, and communication systems, all of which have a large number of contact points made of silver. During use, each contact point needs to work millions of times, must be wear-resistant and have reliable performance, and can withstand strict working requirements. Silver can fully meet various requirements.
rgentum is a type of transition metal with the chemical symbol Ag. Silver is one of the metals known and utilized in ancient times, and is an important precious metal. Silver exists as a single element in nature, but the vast majority exists in the form of compounds in silver ore. The physical and chemical properties of silver are relatively stable, with good thermal and electrical conductivity, soft texture, and rich ductility. Its reflectivity is extremely high, reaching over 99%, and it has many important applications.

Application:
Electronic appliances are the industry with the largest amount of silver usage, which is divided into electrical contact materials, composite materials, and welding materials. Silver and silver based electrical contact materials can be divided into pure silver, silver alloys, silver oxides, and sintered alloys. The annual production of silver and silver based electrical contact materials worldwide is approximately 2900-3000 tons. Composite materials are materials prepared using composite technology, which are divided into silver alloy composite materials and silver based composite materials. From the perspective of silver saving technology, silver composite materials are a new type of material with great potential for development. Silver welding materials such as pure silver solder, silver copper solder, etc.
Photosensitive material
Silver halide photosensitive materials are one of the fields with the highest amount of silver used. The several photosensitive materials with the highest production and sales volume are photographic film, photographic paper, X-ray film, fluorescent information recording film, electron microscope photographic film, and printing film. In the 1990s, the world's photographic industry used approximately 6000-6500 tons of silver. Due to the development of electronic imaging and digital imaging technology, the usage of silver halide photosensitive materials has been reduced. However, the application of silver halide photosensitive materials is still irreplaceable in some aspects and there is still a lot of market space.
