Aluminum bronze is a high-performance copper alloy that successfully combines high strength, high hardness, and excellent corrosion and wear resistance. Although its cost is generally higher than that of brass and ordinary tin bronze, its long service life and high reliability make it an irreplaceable key material in demanding working conditions (such as marine environments and high-load wear applications).
We offer a wide range of aluminum bronze products, including wire, rods, and plates. Each product is designed to meet specific performance requirements. Our product range includes:
Aluminum bronze wire is a product that "wire-materializes" the superior properties of aluminum bronze alloy. It is particularly suitable for solving the linear material requirements of working conditions that combine high strength, high wear resistance, and corrosion resistance, especially in the fields of wear-resistant screens, high-performance springs, and special welding materials, where it is almost an irreplaceable choice.
Aluminum bronze rod are one of the "secret weapons" for engineers facing challenges of high strength, high wear resistance, and corrosion resistance. When stainless steel's wear resistance is insufficient, ordinary carbon steel is prone to corrosion, and brass or tin bronze lacks strength, aluminum bronze bars become an ideal choice. They provide a reliable material basis for manufacturing various durable industrial parts.
Aluminum bronze alloys come in various grades, each with its own specific properties and elemental composition:
C95400: Aluminum: 10.0 - 11.5, Iron: 3.0 - 5.0, Manganese: ≤ 0.50, is a high-strength cast aluminum bronze with balanced performance, reliability, and economy. It has almost become synonymous with "heavy-duty, wear-resistant, and corrosion-resistant" aluminum bronze components. When designing a component that needs to operate reliably for extended periods under harsh conditions, C95400 is often a safe and reliable choice.
C63000 (QAl10-4-4): Aluminum: 9.0 - 11.0, Nickel: 4.0 - 5.5, Iron: 0 - 4.0, Manganese: 1.5 Max. It boasts extremely high strength and hardness, excellent corrosion resistance, especially against dealuding corrosion and cavitation erosion. Inheriting the low coefficient of friction and anti-galling properties of the aluminum bronze family, it also exhibits superior wear resistance compared to C95400 due to its higher hardness.
C62300: 8.5-9.5% aluminum, 2.0-3.0% iron, is a high-strength aluminum bronze alloy highly valued for its excellent corrosion resistance (especially in seawater) and good wear resistance. It is the material of choice for critical components in marine, chemical, and other heavy industrial applications that require both high strength and high durability.
The properties of aluminum bronze can vary significantly depending on its specific composition (especially the content of aluminum and iron).
Density: Approximately 7.64 g/cm³
Thermal conductivity: Approximately 1.5 times that of carbon steel, but only about 15% that of pure copper.
Electrical conductivity: Moderate conductivity, unsuitable for use as a highly conductive material (such as electrical wires).
Aluminum bronze possesses very high strength, comparable to or even exceeding that of many grades of steel.
Aluminum bronze can replace steel as a structural component in harsh corrosive environments (especially seawater), such as ship propellers, pump shafts, and valves.
Its high strength and low coefficient of friction make it an ideal material for manufacturing wear-resistant parts such as bearings, bushings, gears, and worm gears.
In applications involving high-frequency vibration and corrosive environments (such as offshore platform structures and pump components), its performance far surpasses that of ordinary steel.
In industries with risks of flammable and explosive gases, such as oil, natural gas, chemical, and mining, they are used to manufacture tools, shovels, and impact components.
Q: Will aluminum bronze rust? Will it develop green patina like copper?
A: It will corrode, but it won't develop verdigris. The aluminum in aluminum bronze preferentially forms a dense, strongly adhering aluminum oxide film. This film is very stable and effectively prevents further corrosion of the internal copper, so it almost never produces verdigris.
Corrosion patterns: In extremely harsh chemical environments, aluminum bronze may experience "dealuminization corrosion" (selective corrosion), but this problem can be greatly mitigated by controlling the alloy composition (such as by adding nickel).
Q: Can aluminum bronze be welded?
A: Yes, aluminum bronze is generally considered to have good weldability, but the correct process and welding materials must be used.
Q: What are the main disadvantages of aluminum bronze?
A:
High cost: Raw materials (copper, aluminum) are expensive, and processing costs (casting, heat treatment) are also high.
Medium machinability: Its strength and toughness make machining more difficult than low-carbon steel or brass, requiring high-quality cutting tools.
Sensitive to heat treatment: Improper heat treatment can severely affect its performance.
