What are the main components of silver amalgam?

The main components of silver amalgam include silver, copper, tin, and zinc, which work together to provide the desired properties for dental restorative materials. Silver serves as the primary metallic component, contributing to the strength and durability of the amalgam. Copper enhances the strength and corrosion resistance, while tin aids in the amalgamation process and affects the material's working properties. Zinc is often included in controlled amounts to prevent oxidation and enhance the setting characteristics of the amalgam.

This combination of metals allows silver amalgam to be highly effective for dental restorations, not only due to its mechanical strength but also for its long-term performance in the moist environment of the mouth. The inclusion of materials like tin and zinc is crucial for ensuring that the amalgam can withstand the stresses of chewing and maintain integrity over time.
