ASTM B631 Class B vs. Grade 705C Zirconium
Both ASTM B631 class B and grade 705C zirconium are otherwise unclassified metals. There are 12 material properties with values for both materials. Properties with values for just one material (15, 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 ASTM B631 class B and the bottom bar is grade 705C zirconium.
