Original-supplier branded Castadur-30 / AlZn3Mg3Cr, not generic AlZn3Mg3Cr. The 2015 overview, 2016 handbook, technical sheet and current product page are one issuer. The detailed 2016 p. 48 Fe and Cr values differ from the 2015 overview/2016 summary; neither element is published. A process-sheet maximum Si content of 0.14% is not substituted for the p. 48 ingot limit of 0.15%. The T1 mechanical row has no reported wall thickness or ageing duration. The p. 104 ageing diagram remains undigitized.

가공 특성

출처가 보고한 비교이며 인증된 한계값이 아닙니다.

물성보고된 값
post melting temperature limitAfter melting down: maximum 820 °C; supplier instructs temperature check.
refining start temperatureWhen impeller or gas-flushing lance treatment is used, the supplier recommends a starting temperature strictly above 780 °C to account for cooling.
rotor refiningQuick-running gas rotor: argon or nitrogen 7–10 L/min for 3–6 min.
refining qualityWith effective refining the supplier says density index DI <1 can be achieved and maintained; this is guidance, not a test result for each casting.
sand pouring temperatureApproximate sand-casting pour 720–760 °C, with 730 °C recommended; depends on design, size and wall thickness.
gravity pouring temperatureApproximate gravity die-casting pour 730–760 °C, with 750 °C recommended; depends on design, size and wall thickness.
model design shrinkageSupplier model-design shrinkage allowance: 1.0–1.3%; this is not substituted for measured linear shrinkage in the physical table.
gravity die temperatureGravity die temperature 250–400 °C depending on casting; supplier recommends 350 °C to reduce cracking.
grain refiner after holdingAfter long holding with high return use, a small grain-refiner addition such as AlTi5B1 wire 0.5 kg/t is recommended just before pouring; not a composition limit.
cast removalCastings are still soft when removed from sand mould or gravity die; dimensionally critical castings require careful removal.
self ageing contextThe general technical chapter names Castadur-30 among self-ageing high-zinc alloys and says strength increase is normally complete eight days after mould removal; this is not assigned as the precise duration of the T1 mechanical specimen row.
ageing figure provenanceThe handbook p. 104 Figure 9 plots Castadur-30 French gravity-die test-piece properties versus days after casting; curves have not been digitized into numerical claims.
