Types and Differences of Silver

Silver, as a precious metal widely used in industries, jewelry, investment, and other fields, has various types. The differences between these types are mainly reflected in purity, alloy composition, performance, and usage. Here are some common types of silver and their differences.

1. Pure silver (99.9% purity): Pure silver, also known as thousand foot silver, is silver with a purity of 99.9%. Pure silver has high conductivity and thermal conductivity, but its texture is relatively soft, with low tensile strength and hardness, making it prone to deformation when making jewelry and utensils. Pure silver has a wide range of applications in the electronics industry, photography, and catalyst manufacturing.

2. Pure silver (99.99% purity): This type of silver is also known as the Four Nine Pure Silver, and its purity reaches 99.99%. The properties of four nine pure silver are similar to 99.9% pure silver, but due to higher purity, their conductivity and thermal conductivity are better. This type of silver is mainly used in high-tech fields such as semiconductors and solar cells.

3. Cubic crystal silver: Cubic crystal silver is a type of silver with a cubic crystal structure, and its purity is generally above 99.9%. Cubic crystal silver has high conductivity, thermal conductivity, and reflectivity, and is widely used in the electronic industry, solar cells, optical devices, and other fields.

4. Hard silver alloy: Hard silver alloy refers to improving the hardness and wear resistance of silver by alloying with other metals (such as copper, zinc, nickel, etc.). This silver alloy has a wide range of applications in jewelry manufacturing, coin making, and other fields. For example, an alloy composed of 92.5% silver and 7.5% copper is called pure silver, and its hardness and wear resistance are much higher than pure silver.

5. Medical silver: Medical silver is a special silver alloy with a purity typically above 99%. This type of silver has antibacterial, antiviral, and antifungal properties, making it widely used in medical devices, pharmaceuticals, water treatment, and other fields.

6. Silver foil: Silver foil is an extremely thin silver sheet with a purity typically above 99%. Silver foil has excellent conductivity, thermal conductivity, oxidation resistance, and plasticity, making it widely used in fields such as electronic industry, art decoration, and food packaging. For example, silver foil plays an important role in capacitors, Electrical connector and printed circuit boards.

7. Precious metal bonded silver: Precious metal bonded silver is a composite material made by bonding silver with other precious metals (such as gold, platinum, etc.). This silver material has important applications in jewelry manufacturing, contact materials, and other fields. Precious metal bonded silver not only provides the conductivity and thermal conductivity of pure silver, but also enhances wear resistance and corrosion resistance.

8. Silver powder and silver slurry: Silver powder is a granular silver material with excellent conductivity and thermal conductivity. Silver powder has important applications in fields such as conductive coatings, conductive adhesives, and contact materials. Silver slurry is a highly conductive slurry made by mixing silver powder with organic solvents, adhesives, etc. It is widely used in fields such as printed circuit boards, solar cells, touch screens, etc.
