화학 조성

검토를 마친 질량 백분율(wt%) 한계만 표시합니다. 비어 있는 한계는 다른 쪽 한계만 보고되었다는 뜻입니다.

Unifont-90 is a supplier-branded grade, not a generic AlZn10Si8Mg equivalence. Unifont-90 and -94 have distinct composition limits and casting routes despite the same chemical denomination. The 2015 overview, 2016 handbook, technical PDF and current product page are one issuer, not independent votes. The T1 mechanical rows do not give wall thickness, test temperature, specimen size or exact ageing duration. Parenthetical casting minima, where printed, apply only to walls up to 20 mm. Fatigue cycle count and stress ratio are not reported. REACH ingredient disclosures are not ingot limits. The detailed 2016 Si interval 8.5–9.5% conflicts with the 2015 overview and 2016 summary at 8.5–9.3%; Si is withheld.

물성보고된 값
copper impurity avoidanceSupplier says even 0.05 mass % Cu impurity in the melt should be avoided; process guidance, not a second ingot specification.
magnesium makeup thresholdSupplier recommends Mg compensation if total melt Mg falls below 0.25 mass %, using Mg master alloy or pure magnesium.
post melting temperature limitAfter melting, keep at or below 780 °C and check temperature.
rotor refiningQuick-running gas rotor: argon or nitrogen 7–10 L/min for 6–10 min.
sand pouring temperatureApproximate sand-casting pour 710–740 °C; depends on casting method, design, size and wall thickness.
gravity pouring temperatureApproximate gravity die-casting pour 720–750 °C; depends on casting method, design, size and wall thickness.
gravity die temperatureGravity die temperature 300–400 °C depending on casting.
expedited ageingOnly if the cast is used straight away, supplier recommends ageing at 100–120 °C for 10–16 h; not assigned to the published T1 test specimens.
temperature figure provenanceHandbook p. 83 plots Unifont-90 T1 24 h yield strength versus test temperature; curve values have not been digitized or assigned to the room-temperature performance row.
