Aluminum ACP 5080-STD
Properties of the STD condition, compared with the other ACP 5080 tempers.
The only commercial condition: use for jigs, fixtures, vacuum plates and mould bases where post-machining stability matters more than strength.
What is ACP 5080-STD?
ACP 5080-STD is ACP 5080 in the STD condition — the only commercial condition: use for jigs, fixtures, vacuum plates and mould bases where post-machining stability matters more than strength. ACP 5080-STD 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). ACP 5080-STD 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).
Advantages
- Easy to machine — 92/100, better than 99% of aluminum grades
Limitations
- Hard to polish — 35/100, worse than 98% of aluminum grades
- Low strength — 110 MPa (16 ksi), worse than 81% of aluminum grades
- Limited ductility — 3%, worse than 79% of aluminum grades

Working with ACP 5080-STD
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.
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.

ACP 5080-STD — frequently asked
What is ACP 5080-STD used for?
ACP 5080-STD is typically used for machining fixtures and jig plates, vacuum forming tools and vacuum chucks, injection mould bases and frames, inspection and check fixtures, automation and packaging machine base plates and flat gauge and index plates. In short: cast 5083 mold plate.
What is the yield strength of ACP 5080-STD?
ACP 5080-STD 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-STD easy to machine?
Yes — machinability is rated excellent (92/100, better than 99% of aluminum grades). 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-STD 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.
What surface finishes work on ACP 5080-STD?
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.
Can ACP 5080-STD 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.
What is the maximum service temperature of ACP 5080-STD?
ACP 5080-STD is rated for continuous use to about 150°C (302 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
