What else do you need to know about the 2618 aluminum bar?
1.Comparison of 2618, 2219, and 4032 aluminum alloys
As heat-resistant aluminum alloys, 2618, 2219, and 4032 have distinct characteristics:
2618 vs 4032
Alloy composition: 2618 is primarily an aluminum-copper alloy with magnesium and nickel additions, offering high strength and excellent high-temperature performance. 4032 is a high-silicon aluminum alloy containing magnesium, nickel, and copper, known for its low thermal expansion and high wear resistance.
Strength: 2618 has higher tensile and yield strengths, and both alloys perform well at elevated temperatures. However, 4032 excels in wear resistance and offers lower thermal expansion.
2618 vs 2219
Alloy composition: 2618 is primarily an aluminum-copper alloy with magnesium and nickel additions, providing excellent high-temperature strength and mechanical properties under stress. 2219 is also an aluminum-copper alloy but offers superior strength retention and oxidation resistance at higher temperatures.
Weldability: 2618 is chosen for high-stress components that don't require welding, such as engine parts, due to its excellent high-temperature strength. 2219, on the other hand, is ideal for applications where joints must be strong and durable at high temperatures because of its superior weldability.
2.How strong is EN AW-2618A aluminum bar?
2618 has a high tensile strength, typically ranging from 380 to 440 MPa. It outperforms 2014-T6 but is slightly lower than 7075-T6. This makes it suitable for applications requiring a material that can withstand significant loads without deformation.
3.Why is the 2618A aluminum bar suitable for racing pistons?
2618 aluminum bar is chosen for racing pistons due to its ability to absorb large amounts of extreme heat while minimizing damage.
