Alloy C954 is the most popular general-purpose aluminum bronze, used in heavy-load applications for its high resistance to corrosion and oxidation.

Aluminum bronze, a copper-based alloy with aluminum as the main element, includes iron and manganese for high-strength, heat-resistant properties. Typically containing up to 11.5% aluminum, it may also include iron, nickel, and manganese to enhance performance. Aluminum bronze can be heat-treated for increased strength, surpassing that of tin bronze.

Aluminum Bronze Bearings and Bushings – Custom Rapid Manufacturing. Bronze is commonly used in the production of bearings, bushings, washers, and wear plates due to its low metal-on-metal friction.

Aluminum bronze is a copper-based alloy with aluminum as the primary alloying element, along with iron and manganese. It is a high-strength, heat-resistant bronze.

In casting aluminum bronze, the aluminum content typically does not exceed 11.5%. Iron, nickel, manganese, and other elements may be added to enhance performance. Aluminum bronze can be heat-treated and strengthened, offering higher strength than tin bronze and better resistance to high-temperature oxidation.

It has high strength and excellent wear resistance, making it ideal for screws, nuts, copper sleeves, seal rings, and other wear-resistant parts. Its most notable feature is its wear resistance.

Aluminum bronze with iron and manganese elements offers high strength and wear resistance. It can be quenched and tempered to improve hardness, and it provides good corrosion and oxidation resistance in the atmosphere, fresh water, and seawater. It is machinable, weldable, but not easily brazed, and performs well under hot pressure processing. China is capable of producing it.

Performance

Aluminum bronze possesses numerous excellent properties. It has high strength, hardness, and wear resistance, making it suitable for gear blanks, threads, and other components. Its good corrosion resistance allows it to be used in corrosion-resistant parts like propellers and valves. It does not produce sparks on impact, making it suitable for non-sparking tools. With excellent thermal conductivity and stable stiffness, it is used as a mold material in stainless steel plate heat exchangers, preventing mold sticking and workpiece scratching. It also has a shape memory effect and is used as a shape memory alloy. Aluminum bronze is relatively inexpensive, serving as a replacement for more expensive materials like tin bronze, stainless steel, and nickel-based alloys. Its excellent properties have made it increasingly popular and significant in both civilian and military industries.

Exploring the impact of chemical composition on the properties and structure of aluminum bronze remains a key area of interest. Defining the optimal composition for the alloy is challenging. For instance, iron is added to refine the grain, reduce “spontaneous temper brittleness,” and enhance mechanical properties, but excessive iron leads to Fe3Al2 compound precipitation, which impairs these properties, hence iron content should be kept below 5%. Zinc exemplifies another element with mixed reviews—some studies suggest it enhances metal plasticity by forming a solid solution, while others consider it an impurity. The effects of alloying elements shouldn’t be generalized; appropriately adding them, such as iron, manganese, or nickel, enhances mechanical properties, forming different types of aluminum bronze. The content requirements for impurity elements remain unclear, recognized to variations in aluminum bronze types and applications. Ongoing research should focus on understanding chemical composition effects, operational mechanisms, and broadening application scopes.

Aluminum bronze alloys often undergo strengthening processes to achieve desired properties. Key strengthening methods include solid solution strengthening, fine grain strengthening, and aging strengthening. In solid solution strengthening, the alloy is heated to dissolve elements like aluminum and manganese into the copper matrix, forming a saturated or supersaturated solution, which is then quenched. This solution decomposes and precipitates at room or higher temperatures, enhancing the alloy’s strength and hardness through aging strengthening. Solid solution and aging processes are typically combined to boost aluminum bronze alloy properties.

Focusing on aluminum bronze with a composition of 11.5% to 15% aluminum, this variant has similar elemental components to standard aluminum bronze, except for higher aluminum content. This allows it to achieve higher strength and hardness comparable to alloy steel. Consequently, it is extensively used in structural and transmission parts.
