QAL9-4 Brass BushingBearing, Self-lubricating
QAL9-4 is a type of brass alloy, often used in the manufacturing of bushings due to its favorable combination of mechanical properties and corrosion resistance. The “QAL” designation typically refers to a general category of alloys that contain copper (Cu), aluminum (Al), and lead (Pb), with the numbers indicating the approximate percentages of these elements. In the case of QAL9-4, it suggests approximately 9% aluminum and 4% lead content.
Properties of QAL9-4 Brass
- Good Corrosion Resistance: QAL9-4 brass has good resistance to corrosion, making it suitable for use in environments where exposure to moisture, chemicals, or saltwater is common.
- High Strength and Hardness: The aluminum in the alloy increases the strength and hardness, which is beneficial for bushings that need to withstand heavy loads and abrasive conditions.
- Lead Content for Lubricity: The lead content in QAL9-4 brass improves its lubricity, which is essential for bushings to minimize friction and wear between moving parts.
- Machinability: QAL9-4 brass is known for its good machinability, allowing for the production of bushings with precise dimensions and finishes.
Applications of QAL9-4 Brass Bushings
QAL9-4 brass bushings are used in a variety of applications due to their durability and performance characteristics:
- Automotive Industry: In the manufacturing of bearings, gears, and other components that require high strength and wear resistance.
- Marine Applications: For equipment that is exposed to saltwater and corrosive environments, such as propeller shafts and other moving parts.
- Industrial Machinery: In pumps, compressors, and other machinery where components need to operate smoothly under load.
- Construction and Infrastructure: For bearings in heavy equipment and structural components that must withstand harsh conditions.
Manufacturing Process
QAL9-4 brass bushings can be manufactured using various methods, including:
- Casting: The alloy is melted and poured into molds to create the desired shape of the bushing.
- Forging: The alloy is heated and shaped by applying force, which can improve the grain structure and mechanical properties.
- Machining: The alloy is cut and shaped using tools and equipment to achieve the required dimensions and tolerances.

The closest alloys to QAL9-4 in terms of ASTM B505 and European Standard EN 1982
QAL9-4 brass bushings with graphite are a type of self-lubricating bearings that incorporate graphite as a lubricant to enhance their performance under various operating conditions. The QAL9-4 brass alloy itself is known for its good mechanical properties and corrosion resistance, but the addition of graphite further improves its wear resistance and reduces the need for external lubrication.
Benefits of Graphite in QAL9-4 Brass Bushings
Self-Lubrication: Graphite particles embedded in the brass matrix provide a dry lubricant that reduces friction and wear, especially in applications where lubrication may not be readily available or where frequent lubrication is undesirable or impractical.
Improved Wear Resistance: The presence of graphite increases the bearing’s ability to withstand wear, extending the service life and reducing the need for maintenance or replacement.
Reduced Friction: Graphite is known for its excellent lubricating properties, which help to minimize friction between moving parts, leading to smoother operation and reduced energy consumption.
Operational Efficiency: The self-lubricating nature of graphite-embedded bushings allows for more efficient operation in environments where high temperatures, high pressures, or corrosive substances are present.
Versatility: These bushings can be used in a wide range of applications, from automotive and industrial machinery to heavy equipment and marine engineering, where high performance and low maintenance are required.
The closest alloys to QAL9-4 in terms of ASTM B505 and European Standard EN 1982, we first need to clarify what QAL9-4 refers to in the context of alloy standards.
QAL9-4 is a designation commonly used in China for a copper-aluminum alloy, also known as Aluminum Bronze. This alloy typically contains about 9% aluminum and 4% iron, with the rest being primarily copper. It’s known for its high strength and excellent corrosion resistance, particularly in marine environments.
For ASTM B505, a similar aluminum bronze alloy would likely be one of the C95400 series, which are aluminum bronzes with approximately 9% aluminum. These alloys are known for their high strength and resistance to wear and corrosion.
For EN 1982, the closest equivalent might be the CC333G alloy, which is an aluminum bronze with a similar composition. This European standard specifies aluminum bronze with high tensile strength and good resistance to corrosion and wear.
Here’s a simplified overview:
| Alloy Specification | Alloy Name | Description |
|---|---|---|
| ASTM B505 | C95400 | An aluminum bronze alloy, known for high strength and excellent corrosion resistance, typically used in heavy-duty applications. |
| EN 1982 | CC333G | An aluminum bronze similar to QAL9-4, offering high strength, excellent wear and corrosion resistance, suitable for similar applications as ASTM C95400. |
These specifications are based on the general characteristics of QAL9-4 and might include slight variations in minor alloying elements that tailor the material properties for specific applications.
