The density of bronze varies depending on its composition and use. Here are the density ranges for several common types of bronze:
1. Tin bronze
Composition: copper + tin (5%-15%)
Density: 8.7 g/cm³ ~ 8.9 g/cm³
Features: Good wear resistance, mainly used for bearings, springs and ship accessories.
2. Aluminum bronze
Composition: copper + aluminum (5%-12%), usually also contains a small amount of iron or nickel
Density: 7.5 g/cm³ ~ 8.4 g/cm³
Features: Strong corrosion resistance, high hardness, used for high-strength mechanical parts, pumps and marine environments.
3. Silicon bronze
Composition: copper + silicon (2%-5%), may contain manganese or nickel
Density: 8.3 g/cm³ ~ 8.8 g/cm³
Features: Strong corrosion resistance, good welding performance, often used in electrical connectors, springs, ship equipment.
4. Manganese bronze
Composition: copper + manganese (1%-4%), may contain iron and nickel
Density: 7.5 g/cm³ ~ 8.0 g/cm³
Features: high strength, good impact resistance, used in heavy machinery, gears and bushings.
5. Lead bronze
Composition: copper + lead (5%-30%), may contain tin or zinc
Density: 8.9 g/cm³ ~ 9.4 g/cm³
Features: good self-lubricating property, often used in bearings and bushings.
6. Phosphor bronze
Composition: copper + tin (3%-10%) + phosphorus (0.1%-0.3%)
Density: 8.8 g/cm³ ~ 8.9 g/cm³
Features: high elasticity, wear resistance, often used in springs, joints and gears.
