Original-supplier 2016 handbook p. 22 names the branded grade AlSi7Mg0.3 / EN 42100. Its p. 22 detailed and pp. 76–81 summary tables are one issuer and one document. Mn has contradictory limits between the detailed and summary chemistry rows. Sand/T6 yield performance lower limits also conflict, so that complete mechanical condition is withheld. Matching UTS, elongation, hardness and wall-qualified casting minima are separate observations. Main mechanical ranges have no reported wall thickness. Bracketed values apply to castings at wall ≤20 mm (p. 75). Fatigue protocol is absent. Other-column Na/Sr indicates modification options, not quantified composition limits. No variant equivalence to Anticorodal-78dv is inferred.

물성보고된 값
rapid meltingMelt promptly in powerful furnaces; replenish preheated ingots and returns in small volumes to limit magnesium loss, gas absorption, oxidation, segregation and entrapped oxides.
salt treatmentSupplier says salt treatment is not needed when melting Anticorodal-70.
magnesium melting lossNormally about 0.05 mass % magnesium melting loss per fusion; this is processing guidance, not an ingot specification.
magnesium correction thresholdFor an Anticorodal-70/-70dv melt with Mg below 0.25 mass %, supplier recommends correction using AlMg master/casting alloy or pure Mg.
post melting skimmingSkim after melting down.
post melting temperature limitAfter melting down, supplier maximum is 780 °C with temperature checking.
rotor degassingFast rotor refining: argon or nitrogen 7–10 L/min for 6–10 min.
nitrogen tablet refiningAlternative flushing tablet: 150–350 L nitrogen per kg tablet using a bell plunger.
granular grain refinementFor granular Anticorodal-70 after skimming: TiB master alloy or tableted flux to nucleation state KF ≥9, corresponding to grain area <2.5 mm².
strontium remodificationFor permanently modified ingots, remodify only after Sr falls below 0.015 mass %; supplier prefers AlSr master alloy containing 5% Sr.
sand sodium modificationSand-casting Na modification alternatives as mass % of charge: 0.03–0.04 vacuum-packed Na, 0.2–0.3 exothermic tablets, or 0.05–0.2 salt granulate. These are alternatives, not simultaneous additions.
thick gravity sodium modificationFor thick-walled gravity die castings or gravity dies with sand cores, Na modification alternatives as mass % of charge: 0.015–0.025 vacuum-packed Na, 0.1–0.2 exothermic tablets, or 0.05–0.2 salt granulate. No numeric wall threshold is stated.
integrated rotor refiningSupplier prefers gas treatment with a rotor, including integrated melt processing while adding sodium-salt granulate.
unmodified pouring temperatureApproximate pouring temperature 720–760 °C for the unmodified route; depends on design, casting size and wall thickness.
permanently modified pouring temperatureApproximate pouring temperature 740–780 °C for the permanently modified route; depends on design, casting size and wall thickness.
gravity die temperatureGravity die temperature 300–400 °C depending on the casting.
standard solution treatmentProcess-sheet standard solution treatment 520–535 °C for 6–10 h, excluding heat-up time.
special component solution treatmentProcess-sheet special-component alternative solution treatment 535–545 °C for 24 h, excluding heat-up time; not assigned to all components.
solution quenchAfter process-sheet solution treatment, quench in 10–40 °C water without delay where possible.
ageing delay if trimmingOnly when trimming is needed, delay before artificial ageing is at most 12 h.
partial ageing t64Process-sheet T64 partial ageing 150–160 °C for 2–3 h for high elongation.
full ageing t6Process-sheet T6 full artificial ageing 155–165 °C for 6–8 h for high strength.
stabilisation thermal loadingFor castings with thermal loading, stabilisation anneal at 210–230 °C for 6–8 h, then air-cool to room temperature.
T6 general heat treatmentGeneral heat-treatment summary: solution 520–545 °C for 4–10 h; water quench at 20 °C; age 155–165 °C for 6–8 h. This is separate from the p. 67 standard/special component process-sheet guidance.
T64 general heat treatmentGeneral heat-treatment summary: solution 520–545 °C for 4–10 h; water quench at 20 °C; age 150–160 °C for 2–3 h. This is separate from the p. 67 process-sheet guidance.
supplier qualitative characteristicsSupplier calls the grade highly corrosion-resistant, weldable and machinable; no standardized corrosion rating, welding test or cutting condition is stated in this paragraph.

anticorodal-70-sand-t6-yts 보류: The original supplier handbook p. 22 gives sand/T6 yield 200–280 MPa, while its p. 78 summary gives 220–280 MPa. The current product page repeats the p. 22 row but is the same issuer. No complete sand/T6 mechanical condition or chart region is published until the issuer resolves the discrepancy.
