The price of steel and aluminum is continually fluctuating based on global supply and demand, fuel costs and the price and availability of iron and bauxite ore; however steel is generally cheaper (per pound) than aluminum (see galvanized vs stainless for more info on steel). Note that these values are derived from empirical tests and fluctuate based on heat treatment, alloy composition, and other factors.

Since 6061 aluminum’s thermal conductivity is generally higher, it is better suited for heat-dissipative applications (such as heat sinks and heat exchangers) than 7075 aluminum is, though 7075 aluminum’s thermal conductivity is also quite good.

Because 7075 has >1% Cu, it is more affected by caustic environments and does not share the high corrosion resistance which other aluminum alloys have. The hardness of a material is its response to local indentation from a standardized force; in this instance, it is found using a 500g force imparted by a 50mm ball onto the metal.

There are 31 material properties with values for both materials.

We bent each of them 25 degrees and used a gauge on the pressure side of our hydraulic ram setup to record the comparative force required. Type 6061 aluminum is from the 6xxx class of aluminum, which include those alloys that use magnesium and silicon as their primary elements. It is more susceptible to embrittlement than many other aluminium alloys because of microsegregation, but has significantly better corrosion resistance than the 2000 alloys. If one had to be chosen for its hardness, 7075 aluminum should be specified as it is generally harder than type 6061 alloy.
