Product information

Model: 8090
Availability: Customizable 
8090 aluminum alloy is a lithium-containing aluminum alloy with the following main performance characteristics:
Mechanical properties
‌Hardness‌: It belongs to medium-high hardness aluminum alloy. The specific value is not explicitly mentioned, but based on the search results, its hardness may be between the 5 series and the 3 series.
‌Strength‌: The tensile strength and yield strength are high, making it suitable for structural components that can withstand large pressures.
‌Fatigue performance‌: The fatigue life under artificial aging is higher than that under natural aging, and it still maintains good fatigue performance at high temperatures ranging from room temperature to 200°C.
Processing properties
‌Cutting processing‌: The processing difficulty is moderate. Suitable tools (such as ultra-fine particle hard alloy tools) need to be selected and parameters (cutting speed 200-350 meters/minute, feed rate 0.1-0.5 millimeters/revolution) need to be optimized.
‌Forming properties‌: The forming performance is best in the annealed state, but it decreases after heat treatment. Corrosion resistance
Corrosion Resistance: Generally, it is believed that 1 series pure aluminum has the best corrosion resistance, followed by 5 series, while 2 series and 7 series have poorer corrosion resistance. As 8090 is a lithium-containing alloy, it is speculated that its corrosion resistance may be close to that of traditional high-strength aluminum alloys.
Other Characteristics
Heat Conductivity: The heat conductivity is moderate, suitable for insulation and heat preservation needs.
Application Scenarios: Suitable for scenarios requiring high strength and stability, such as buildings and mechanical components.
