Proprietary Gränges DISPAL S220 powder-metallurgy product, not an AA/EN grade equivalence. The issuer portfolio calls its nominal composition AlSi35; no certified chemical limits are published. Manufacturer mechanical numbers are preliminary minimums for Ø30 mm specimens and reference values for other geometries. Density carries the printed ±5% tolerance.
Physical and thermal properties
| Property | Reported value | Unit | Condition |
|---|---|---|---|
| density | 2.54 | g/cm³ | At 20°C; manufacturer reports ±5% |
| thermal conductivity | 152.4 | W/(m·K) | Thermal conductivity at 30°C |
Additional property data
Source-reported values, specification intervals, minimums and strict bounds; an average is labeled only when the source reports it. Compare conditions before use.
| Property | Value | Condition |
|---|---|---|
| ultimate tensile strength | ≥ 165 MPa | F state, Ø30 mm specimen, tensile test at 20°C; preliminary minimum defined as mean minus 3 sigma; other geometries reference only |
