How does the hardness of aluminum compare to cast iron for Outdoor Square Tables?

When choosing materials for outdoor square tables, understanding the hardness of aluminum versus cast iron is crucial for durability and performance. Aluminum is known for its lightweight nature and resistance to corrosion, making it a popular choice for outdoor furniture. However, its hardness is significantly lower than that of cast iron. On the Brinell hardness scale, aluminum typically ranges between 15 and 120 HB, depending on the alloy, while cast iron can range from 150 to 350 HB.

Cast iron's higher hardness makes it more resistant to scratches and dents, which is ideal for high-traffic outdoor settings. However, its weight and susceptibility to rust can be drawbacks. Aluminum, though softer, offers excellent weather resistance and is easier to maintain. For outdoor square tables, the choice between aluminum and cast iron ultimately depends on the desired balance between hardness, weight, and maintenance requirements.
