Zinc Alloy Slush Metal vs Zinc Anode Alloy
Zinc Alloy · grade comparison
Zinc Alloy Slush Metal and Zinc Anode Alloy are both zinc alloy grades. Slush Metal is the stronger of the two: yield strength 130 MPa (18.9 ksi) against 50 MPa (7.25 ksi) for Zinc Anode Alloy, about 160% more; tensile strength follows at 180 MPa (26.1 ksi) vs 80 MPa (11.6 ksi). In exchange, Zinc Anode Alloy is the more ductile: elongation 8% versus 3% for Slush Metal, and Slush Metal is harder (70 HB vs 38 HB). Slush Metal is lighter (6.6 g/cm³ vs 7.13 g/cm³ for Zinc Anode Alloy) and Zinc Anode Alloy is stiffer (100 GPa vs 85 GPa). On the shop floor, Slush Metal sits in a lower cost tier (standard, $$) than Zinc Anode Alloy (premium, $$$).
Slush MetalChoose it when strength drives the design, or when weight is the constraint.
Zinc Anode AlloyChoose it when the part is bent, formed or impact-loaded.
Slush Metal vs Zinc Anode Alloy: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all zinc alloy grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.
