Purchasing guidance of 2618 aluminum bar
Comparison of 2618 aluminum alloy with some commonly used alloys
- 2024 vs. 2618: 2024 aluminum alloy is known for its high strength and good fatigue resistance, making it a popular choice for aerospace structures. However, its heat resistance is lower than that of 2618. The 2618 alloy offers better creep resistance, making it more suitable for high-temperature applications such as engine components.
- 7075 vs. 2618: 7075 is one of the highest-strength aluminum alloys, commonly used in aerospace and structural applications requiring high strength. However, 7075's performance at high temperatures is inferior, as it tends to lose strength under heat. In contrast, 2618 has better high-temperature stability and creep resistance, making it ideal for high-heat applications like pistons.
- 4032 vs. 2618: 4032 is also a popular aluminum alloy for pistons due to its low thermal expansion and good wear resistance. While 2618 has higher strength at elevated temperatures, 4032 is preferred for applications needing dimensional stability under temperature changes. The choice often depends on specific requirements for thermal expansion in high-temperature uses.
- 6061 vs. 2618: 6061 is a versatile alloy with good machinability and corrosion resistance, but it lacks the strength and heat resistance of 2618. While 6061 is widely used for structural purposes, 2618's superior high-temperature performance makes it better suited for applications that demand high strength under thermal stress.
