Commonly Perforated Aluminium Types
This commercially pure, low-strength alloy has excellent corrosion resistance and satisfactory anodising and coating finishes. It is unmatched by any other commercial aluminium alloy for workability.
A widely used general-purpose alloy because of its good corrosion resistance, moderate strength, formability, and weldability. This alloy may show some slight discolouration when anodised, but reacts well to other coating finishes.
Comparable to AlMn1 in strength and formability, this alloy has superior finishing characteristics making it much better for anodising.
A versatile high-strength alloy with good forming characteristics and excellent corrosion resistance. Although easily welded, it is not recommended for brazing and soldering applications. Anodised coatings may take on a yellowish tint if applied too thickly.
If an aluminum type is not specified, Europerf companies will use Al99.5 which is the most commonly perforated alloy for pricing and production.
