What is ACP 5080?
ACP 5080 is a continuously cast, precision double-side milled aluminum tooling plate from Aleris/Novelis in the same class as MIC-6, Alca 5 and K100-S, based on an Al-Mg (5083-type) composition. Its value is very low internal stress, isotropic free machining and tight flatness and thickness tolerance, typically ±0.13 mm, so parts stay flat after heavy stock removal — hence its use for fixtures, gauges, vacuum chucks, mould bases and machine base plates. Strength and elongation are well below 6061-T651 rolled plate, it cannot be cold formed, welds pick up porosity, and anodizing looks dark and mottled, so it is not a structural or cosmetic material. ACP 5080 has a density of 2.8 g/cm³ (0.101 lb/in³), heavier than 81% of aluminum grades. It melts at 570°C (1,058 °F). ACP 5080 has a yield strength of 110 MPa (16 ksi) and a tensile strength of 172 MPa (24.9 ksi) — weaker than 81% of aluminum grades. Elongation at break is 3% and the elastic modulus is 71 GPa (10.3 Msi).

Physical3
ACP 5080 has a density of 2.8 g/cm³ (0.101 lb/in³), heavier than 81% of aluminum grades. It melts at 570°C (1,058 °F).
Mechanical11
ACP 5080 has a yield strength of 110 MPa (16 ksi) and a tensile strength of 172 MPa (24.9 ksi) — weaker than 81% of aluminum grades. Elongation at break is 3% and the elastic modulus is 71 GPa (10.3 Msi).
Thermal6
ACP 5080 is rated for continuous service to 150°C (302 °F). It conducts heat at 142 W/m·K (82 BTU/hr·ft·°F), better than 51% of aluminum grades. Thermal expansion is 23.4 µm/m·K (13 µin/in·°F).
Electrical3
ACP 5080 conducts electricity at 36 % IACS, better than 55% of aluminum grades.
Chemical & Environmental3
Corrosion resistance is good (55/100), worse than 51% of aluminum grades.
Sustainability4
Producing a kilogram of ACP 5080 takes about 210 MJ of energy and emits 12 kg of CO₂ — more than 88% of aluminum grades. Typical recycled content is 80%.
Manufacturability8
ACP 5080's machinability is excellent (92/100, better than 98% of aluminum grades); weldability fair (45/100); formability not recommended (12/100).

Working with ACP 5080
Is ACP 5080 easy to machine?
Machines very freely and chip-breaks well at high speed with polished-flute carbide; because it is nearly stress-free, thin ribs and large flat plates hold size after heavy stock removal.
Can ACP 5080 be welded?
TIG/MIG possible with 4043/5356 for repair only — cast porosity causes gas pickup and the HAZ loses the stress-relieved stability that makes the product worthwhile.
Can ACP 5080 be formed, bent or molded?
Not a forming alloy: with ~3 % elongation it cracks on bending or rolling; design for machined, bolted or doweled assemblies.
Manufacturability
The process limits FabDigit applies to ACP 5080. Every ACP 5080 part is priced by an engineer; design inside these and the quote comes back without a redesign loop.

What surface finishes work on ACP 5080?
Accepts primer/paint and chemical conversion coating well; anodize (especially hard-coat) is acceptable for wear but appears dark and mottled, and high-polish mirror finishes are limited by micro-porosity.

What is the yield strength of ACP 5080?
ACP 5080 has a typical yield strength of 110 MPa (16 ksi) and a tensile strength of 172 MPa (24.9 ksi) — weaker than 81% of aluminum grades.
Is ACP 5080 easy to machine?

Can ACP 5080 be welded?
With care — weldability is rated fair (45/100). TIG/MIG possible with 4043/5356 for repair only — cast porosity causes gas pickup and the HAZ loses the stress-relieved stability that makes the product worthwhile.
