Magnesium and chromium in the alloy enhance its corrosion resistance, making it ideal for applications that are exposed to weathering and salty marine environments. This makes aluminum 5050 alloy an ideal choice for durable, low-maintenance products in multiple industries.

Heat Resistance

UNS A95050 can withstand temperatures up to 300oC for extended periods of time. This is at no cost to its structural integrity and performance. As well as its impressive heat resistance, aluminum 5050 has good oxidation resistance. This adds further value to its use as an industrial alloy.

Due to its ability to withstand oxidation, there is no need for additional coatings on components constructed from this alloy. Moreover, this material property prolongs the lifetime of end products.

Heat Treatment

The wear resistance and strength of aluminum 5050 alloy can be improved using UNS A95050 heat treatment. This method employs high temperatures for a short period of time and is comparable to annealing. The material’s microstructure is changed, enhancing its resistance to fatigue cracking and corrosion.
