Supplier-branded Silafont-70 / AlSi12CuNiMg / 48 000, not every generic AlSi12CuNiMg casting. The 2015 overview, 2016 handbook, safety data sheet and current product page are one issuer, not independent votes. Main F/T5/T6 performance ranges do not specify wall thickness, specimen size, test temperature or exact treatment of each specimen; the p. 83 high-temperature curve is not digitized. Parenthetical casting minima apply only to walls ≤20 mm. Detailed p. 36 gravity-die T6 hardness minimum 135 HBW conflicts with summary p. 78 and overview p. 2 minimum 130 HBW; neither minimum is published. The main hardness interval 135–160 HBW agrees. Summary fatigue ranges lack cycle count and stress ratio. Safety-sheet ingredient disclosures and component toxicology are not ingot composition limits or current alloy-specific hazard conclusions.

물성보고된 값
elevated temperature behaviorSupplier qualitatively describes good mechanical properties at higher temperatures; the p. 83 curve is not digitized into numerical data.
절삭성Supplier describes good machining characteristics; no cutting protocol or numeric acceptance criterion in the grade description.
내식성Supplier describes reduced corrosion resistance; no exposure protocol or numeric corrosion rate.
wear slidingSupplier describes good running and sliding properties and wear resistance; no quantified tribology test.
t6 heat treatmentSupplier general table: solution 520–530 °C for 5–10 h, quench water 20–80 °C, age 165–185 °C for 5–8 h. Guidance, not the measured specimen history for every T6 range.
t5 heat treatmentSupplier general table: no solution step, air cooling, age 210–220 °C for 10–12 h. Guidance, not the measured specimen history for every T5 range.
temperature yield figureHandbook p. 83 plots 0.2% 24 h yield strength versus test temperature for several alloys; Silafont-70 is curve d, stabilised T5 gravity-die casting. Curve not digitized into tabular material values.
machining figureHandbook p. 114 Figure 3 compares cutting distance for Silafont-70 granular and permanently modified microstructures versus cutting speed. Curves are not digitized.
water solubilityManufacturer 2015 safety data sheet states water insoluble; this is not a corrosion-rate or compatibility test.

검토 중인 데이터

브리넬 경도 보류: Original-supplier detailed handbook p. 36 and current product page report 135 HBW for the parenthetical gravity-die T6 casting minimum, while the same handbook mechanical summary p. 78 and 2015 overview p. 2 report 130 HBW. Neither minimum is selected pending issuer clarification. The separate performance range 135–160 HBW agrees.
