Description

High Leaded Bronze, also known as leaded bronze, is a versatile alloy prized for its superior castability, machinability, and excellent bearing properties. This material boasts a higher lead content compared to standard bronze alloys, typically ranging from 2% to 4% lead by weight, significantly enhancing its performance characteristics. This makes it an ideal choice for a wide range of applications demanding high-quality castings and intricate machining.

Key Features & Benefits:

• Exceptional Castability: The high lead content dramatically improves fluidity, enabling the production of intricate and complex castings with fine detail. This minimizes porosity and ensures a smooth, consistent surface finish, reducing post-processing requirements.
• Superior Machinability: High Leaded Bronze machines exceptionally well, offering significant advantages in manufacturing speed and efficiency. It readily accepts a variety of machining operations, including turning, milling, drilling, and tapping, with reduced tool wear and improved surface quality.
• Excellent Bearing Properties: The presence of lead provides exceptional self-lubricating qualities, reducing friction and wear in bearing applications. This extends the lifespan of components and minimizes maintenance needs. It's particularly effective in applications involving sliding or rotating motion under moderate loads.
• Good Corrosion Resistance: While not as corrosion-resistant as some other bronze alloys, High Leaded Bronze still offers decent protection against corrosion in many environments. Its resistance to corrosion can be further enhanced through various surface treatments.
• High Damping Capacity: This alloy exhibits excellent damping capacity, meaning it effectively absorbs vibrations and minimizes noise. This property is advantageous in applications where vibration control is critical.

Typical Applications:

• Bushings and Bearings: Its self-lubricating properties make it ideal for various bearing applications, from automotive components to industrial machinery.
• Gears and Sprockets: Its excellent machinability and durability ensure high precision and long service life in these applications.
• Valves and Fittings: High Leaded Bronze's resistance to corrosion and wear makes it a suitable material for components exposed to various fluids.
• Plumbing Fixtures: In specific applications, where corrosion resistance is less critical than its machinability, High Leaded Bronze can be suitable for plumbing components.
• Architectural Components: Its castability allows for the creation of intricate decorative elements and structural components.
