# Half-Hard Nickel Alloy 600

Half-hard nickel 600 is nickel 600 in the half-hard temper. The graph bars on the material properties cards below compare half-hard nickel 600 to: wrought nickels (top), all nickel alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
