SAE-AISI 1049 Steel vs. AWS BAu-6

SAE-AISI 1049 steel belongs to the iron alloys classification, while AWS BAu-6 belongs to the otherwise unclassified metals. There are 15 material properties with values for both materials. Properties with values for just one material (18, in this case) are not shown. Please note that the two materials have significantly dissimilar densities. This means that additional care is required when interpreting the data, because some material properties are based on units of mass, while others are based on units of area or volume.

For each property being compared, the top bar is SAE-AISI 1049 steel and the bottom bar is AWS BAu-6.
