Working with A1N30-H14
Is A1N30 easy to machine?
Rarely machined; very soft and gummy — use sharp polished high-rake carbide, high speed, generous lubricant, and expect burrs on any slitting or die-cutting operation.
Can A1N30 be welded?
Excellent GTAW/GMAW/ultrasonic weldability with 1100 or 1188 filler in thicker gauges; in foil gauges joining is normally ultrasonic, resistance or adhesive lamination since fusion welding burns through.
Can A1N30 be formed, bent or molded?
Outstanding cold formability in O/H22 tempers (deep-draw pouch foil); hard H18/H19 foil work-hardens fast and should be interannealed at 300–380 °C if further forming is needed.
What surface finishes work on A1N30?
Takes clear anodizing, chemical conversion (chromate-free passivation) and PET/PP/nylon lamination well; degrease and remove rolling oil before coating, and etch (DC/AC) for capacitor foil surface area.

A1N30-H14 — frequently asked
What is A1N30-H14 used for?
A1N30-H14 is typically used for electrolytic capacitor foil, precision foil stock, laminated pouch and barrier foil, etched anode foil blanks, thin-gauge electrical strip and foil for heat exchanger fin stock. In short: JIS precision foil grade; 1230-class purity band; formability 98, weldability 90.
What is the yield strength of A1N30-H14?
A1N30-H14 has a typical yield strength of 95 MPa (13.8 ksi) and a tensile strength of 110 MPa (16 ksi) — weaker than 86% of aluminum grades. Strength varies by condition: see the 10 listed tempers.
Is A1N30-H14 easy to machine?
Not especially — machinability is rated fair (35/100, worse than 86% of aluminum grades). Rarely machined; very soft and gummy — use sharp polished high-rake carbide, high speed, generous lubricant, and expect burrs on any slitting or die-cutting operation.
Can A1N30-H14 be welded?
Yes — weldability is rated excellent (85/100). Excellent GTAW/GMAW/ultrasonic weldability with 1100 or 1188 filler in thicker gauges; in foil gauges joining is normally ultrasonic, resistance or adhesive lamination since fusion welding burns through.
What surface finishes work on A1N30-H14?
Takes clear anodizing, chemical conversion (chromate-free passivation) and PET/PP/nylon lamination well; degrease and remove rolling oil before coating, and etch (DC/AC) for capacitor foil surface area.
Can A1N30-H14 be formed, bent or molded?
Outstanding cold formability in O/H22 tempers (deep-draw pouch foil); hard H18/H19 foil work-hardens fast and should be interannealed at 300–380 °C if further forming is needed.
What is the maximum service temperature of A1N30-H14?
A1N30-H14 is rated for continuous use to about 110°C (230 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between A1N30-O and A1N30-H19?
O is the default condition — default soft condition for laminate/pouch foil, deep-drawn packaging and formable foil where maximum elongation is needed. H19: maximum cold work, used for very thin high-tension foil runs and etched capacitor foil substrates. Yield strength is 30 MPa in O versus 150 MPa in H19.
