Bronze has been known to mankind for over 3,000 years as a high-strength alloy based on copper and tin. The metal has increased strength, is not susceptible to corrosion and is easily forged, which is why its scope of application covers most industries. Modern bronze alloys, in addition to the main components, may contain other alloy additions in amounts ranging from 2.5-3% or more. The alloy may contain chemical elements such as lead, chromium, iron and other ingredients that have a beneficial effect on the properties of bronze, and its use has become increasingly popular in recent years.
