What is Aluminum Composite Panel (ACM) PE Core?
Aluminum Composite Panel (ACM) PE Core is Aluminum Composite Panel (ACM) in the PE Core condition — economy build for signage, enclosures and interior panels; combustible core, not for fire-rated façades. Aluminum Composite Panel (ACM) PE Core has a yield strength of 100 MPa (14.5 ksi) and a tensile strength of 130 MPa (18.9 ksi) — weaker than 74% of composite grades. Elongation at break is 5% and the elastic modulus is 70 GPa (10.2 Msi). Aluminum Composite Panel (ACM) PE Core has a density of 1.35 g/cm³ (0.0488 lb/in³), lighter than 75% of composite grades.
Advantages

Working with Aluminum Composite Panel (ACM) PE Core
Is Aluminum Composite Panel (ACM) easy to machine?
Route, saw or shear with carbide tooling; single-flute or O-flute router bits at high spindle speed give a clean edge without melting the core. Drill with sharp twist drills and back the panel to avoid skin burr. Waterjet also cuts it well; laser is not used (the PE core burns and the paint scorches).
Can Aluminum Composite Panel (ACM) be welded?
Not weldable. Join with rivets, self-clinching hardware, adhesive tapes or structural adhesive, or with the folded-return-and-rivet detail used on cladding cassettes.
Can Aluminum Composite Panel (ACM) be formed, bent or molded?
Fold along a 90–110° V-groove routed through the back skin and core, leaving the face skin as the hinge (minimum inside radius about the skin thickness); do not press-brake the full panel because the core delaminates. Gentle roll-curving of the whole panel is possible down to roughly 300 mm radius.
What surface finishes work on Aluminum Composite Panel (ACM)?
Supplied factory-finished (PVDF or polyester coil coat on the face, mill or primer on the back) with a peel-off protective film; keep the film on through routing. Cut edges expose the core and are usually capped with extrusions, folded returns or edge sealant. Field painting and anodizing are not applicable; printing and vinyl application take well on the coated face.
Aluminum Composite Panel (ACM) PE Core — frequently asked
What is Aluminum Composite Panel (ACM) PE Core used for?
Aluminum Composite Panel (ACM) PE Core is typically used for façade and rainscreen cladding, signage and display panels, equipment and electrical enclosures, solar and telecom tower skins, trade-show and retail fixtures and vehicle and trailer body panels. In short: flat, stiff and light; routes and V-groove folds cleanly; PVDF factory finish; core choice sets the fire rating.
What is the yield strength of Aluminum Composite Panel (ACM) PE Core?
Aluminum Composite Panel (ACM) PE Core has a typical yield strength of 100 MPa (14.5 ksi) and a tensile strength of 130 MPa (18.9 ksi) — weaker than 74% of composite grades. Strength varies by condition: see the 3 listed tempers.
Is Aluminum Composite Panel (ACM) PE Core easy to machine?
Yes — machinability is rated very good (80/100, better than 85% of composite grades). Route, saw or shear with carbide tooling; single-flute or O-flute router bits at high spindle speed give a clean edge without melting the core. Drill with sharp twist drills and back the panel to avoid skin burr. Waterjet also cuts it well; laser is not used (the PE core burns and the paint scorches).
Can Aluminum Composite Panel (ACM) PE Core be welded?
Not readily — weldability is rated not recommended (5/100). Not weldable. Join with rivets, self-clinching hardware, adhesive tapes or structural adhesive, or with the folded-return-and-rivet detail used on cladding cassettes.
What surface finishes work on Aluminum Composite Panel (ACM) PE Core?
Supplied factory-finished (PVDF or polyester coil coat on the face, mill or primer on the back) with a peel-off protective film; keep the film on through routing. Cut edges expose the core and are usually capped with extrusions, folded returns or edge sealant.

What is the maximum service temperature of Aluminum Composite Panel (ACM) PE Core?
Aluminum Composite Panel (ACM) PE Core is rated for continuous use to about 80°C (176 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
Can FabDigit make parts in Aluminum Composite Panel (ACM) PE Core?
