| 1) Remark: The material GD-ZnAl4, material NR. 2.4140, characteristic Z 400, one uses for diecastings. If there are high requirements to the accuracy to size of the products produced by diecasting, this alloy should be preferred. The material is substantially more ductile than the other high quality casting alloys. These characteristics however bought by somewhat worse physical properties and a somewhat smaller corrosion resistance in relation to intergranular corrosion in the comparison to Z 410. The casting temperature is about 425 °C (max. 450 °C) amounted to, the form temperature (pressure pouring) is on approximately 180 to max. to adjust 250 °C. |
