1100 Aluminium Bars Uses
Due to its excellent corrosion resistance, Aluminium 1100 Rectangular Bars are commonly used in marine and other harsh environments. It is also used in electrical industry applications such as conductive cables and bus bars. Other common uses include heat exchangers, cooking utensils, and reflectors.
ASTM B211 Aluminium Alloy 1100 Bars Heat Treatment
UNS A91100 bars cannot be heat-treated to increase their strength. However, cold working processes such as rolling and drawing can increase their strength and hardness. Its ductility also increases with annealing treatments.
UNS A91100 Round Bars Corrosion Resistance
1100 Aluminium Bars have excellent corrosion resistance to most common materials. Its protective oxide layer also makes it resistant to atmospheric and water vapor corrosion. However, its resistance to alkaline environments such as cement, mortar, and concrete is limited.
Conclusion:
Aluminum 1100 bars are a widely used aluminum alloy known for their excellent corrosion resistance, high ductility, and good workability. Its composition, physical and mechanical properties, uses, heat treatment, and corrosion resistance make it a popular choice in various industries. Whether used in marine environments, electrical industry, heat exchangers, or cooking utensils, aluminum 1100 bars offer excellent qualities for corrosion resistant applications. Understanding Aluminium Alloy 1100 Industrial Round Bars properties and applications can help you choose the right material for your needs.
