Titanium ZTC4 vs Titanium Grade 1 vs Titanium Grade 2 vs Titanium Grade 3
Side-by-side benchmark of 4 titanium grades.
PropertiesHow to read this table
- The best value in each row is in bold.
- Values are typical room-temperature figures for the default condition (temper / grade as listed).
- Relative cost is a market tier, not a price — it moves with region and volume.
- Confirm against the certified mill / resin datasheet before design release.
