Important Technical Notes
- All data is based on MPIF Standard 35 and typical production parameters.
- Density values are minimum typical values, and actual density depends on processing conditions.
- HT suffix indicates heat-treated condition, typically quench and temper.
- Tensile strength and elongation vary with density and processing route.
- Custom alloy compositions are available upon request.
