화학 조성

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

Supplier-branded Silafont-20 / AlSi11Mg, not every generic AlSi11Mg casting and not the separately named Silafont-20 dv. The 2015 overview, 2016 handbook, technical PDF and current product page are one issuer, not independent votes. Main F/T6 performance rows do not specify wall thickness, specimen size, test temperature or exact treatment of each specimen. Parenthetical casting minima apply only to walls ≤20 mm. Fatigue intervals lack cycle count and stress ratio. The handbook physical summary density 2.64 kg/dm³ and technical PDF 20 °C density 2.65 g/cm³ differ after unit normalization; both are withheld. REACH ingredient disclosures are not ingot composition limits.

검토 중인 데이터

밀도 보류: Original-supplier 2016 physical summary p. 80 and 2015 overview p. 5 give approximate 2.64 kg/dm³; its 2015 version 2 REACH technical PDF p. 4 gives 2.65 g/cm³ at 20 °C. These units are numerically equivalent after conversion but the values differ by 0.01. Temperature/measurement/revision applicability is unresolved; neither density is published.
