Expert notes on EN-GJL/ASTM A48 gray iron: damping, thin-wall capability and machinability. We map grades (Class 30–60 ↔ EN-GJL-200/350), show realistic wall thickness (3–6 mm / 0.12–0.24 in, by process) and typical Ra from green/resin/shell molds.
• Ideal for machine bases, housings, stove/boiler parts.
• Drawings: add ISO 8062 CT and machining stock.

Gray cast iron Who this helps: Design Engineers / Buyers selecting gray/grey iron for housings, bases, brake drums, pulleys and other non-pressure parts where NVH damping, machinability and value matter.What you’ll get: a practical gray iron casting guide—process options, ASTM⇆EN⇆ISO grade mapping, surface finish & CT notes, design rules, copy-paste drawing text, and when to…
Cast Iron Vibration Damping Who this helps: Design Engineers / Buyers targeting low-noise, low-vibration (NVH) housings, bases, pump/gearbox frames, and brackets.What you’ll get: clear physics for damping, when gray/grey iron beats ductile iron or steel, grade & microstructure tips, DFM rules that kill ringing, copy-paste drawing notes, and an acceptance test plan you can run…
A practical selection guide for engineering and sourcing teams: ductile iron vs gray iron: ductile (EN-GJS) vs gray iron (EN-GJL) compared across design rules, cost, machinability, leak-tightness, and service life, with ASTM/EN grade maps, realistic wall-thickness/tolerance tables and a PPAP-ready QC checklist. Executive summary: YBmetal helps you to choose each material Choose ductile iron (spheroidal…
