leaded bronze
Noun 1. A type of bronze alloy: A bronze material to which a small, specific percentage (typically 1-4%) of lead has been intentionally added during its production to alter its physical properties.
Leaded bronze is a technical term used primarily in metallurgy, manufacturing, and materials science. It refers to the specific alloy created by adding lead to bronze. - The primary purpose of adding lead is to improve the alloy's machinability (making it easier to cut and shape) and to provide lubricating properties. - It is distinct from standard bronze (an alloy of copper and tin) due to this deliberate addition of lead.
- Noun:
- The ancient artifact was determined to be made of leaded bronze, which explained its excellent preservation of fine details from casting.
- For this bearing application, the engineer specified leaded bronze because of its self-lubricating characteristics.
- The machinist preferred working with leaded bronze over standard bronze because it produced less tool wear.
- Historical and Archaeological Context: The use of leaded bronze can be an important diagnostic feature when analyzing historical metal objects, as its use varied across different periods and cultures.
- The analysis showed the Roman pipe fitting was leaded bronze, a common practice for such utilitarian items.
- Leaded (adj): Describing a material (often a metal, fuel, or glass) into which lead has been incorporated. (e.g., , ).
- Bronze (noun): The base alloy of copper and tin, without the addition of lead.
- Free-machining bronze: An alternative term sometimes used in engineering to describe leaded bronze, highlighting its key property.
- Leaded tin bronze (a more precise technical synonym).
- Leaded gunmetal (a related alloy; gunmetal is a type of bronze often with zinc, and it can also be leaded).
This term has a single, specific technical meaning. It does not have idiomatic or phrasal verb uses. The definition is consistent across technical fields.
