Two entries need a caution, not a tidy number. Published thermal conductivity spreads across roughly 16 to 22 W\/m·K by source and temperature basis, and electrical resistivity shows the same spread, so sizing should use the figure your design code supports. Hardness is the common trap: neither B265 nor B348 has a hardness column, so a hardness value cannot be rejected against those standards and needs a supplementary test on the order.
