Aluminum Alloys

Start with 6061-T6 — it covers most structural and enclosure work at the best machining cost. Step up to 7075 only when FEA demands aircraft-grade strength, choose 6063 when anodized cosmetics matter most, 5052/5083 for welded or marine assemblies, 2024 for fatigue-critical aerostructure, and MIC-6 cast plate when flatness and dimensional stability beat strength.

6xxx Series (Mg-Si)

Aluminum 6061-T6

The default CNC aluminum: strong enough for most jobs, machines fast, anodizes well.

310 MPa · 95 HB

Machinability

Aluminum 6063-T5

The cosmetic-finish aluminum: silky anodized surfaces for consumer-facing parts.

186 MPa · 60 HB

Machinability

7xxx Series (Zn)

Aluminum 7075-T6

Aircraft-grade aluminum: steel-level strength at a third of the weight.

572 MPa · 150 HB

Machinability

2xxx Series (Cu)

Aluminum 2024-T351

The aerospace fatigue specialist: damage-tolerant alloy for cyclically loaded structures.

470 MPa · 120 HB

Machinability

5xxx Series (Mg)

Aluminum 5052-H32

Marine-grade and weldable: for parts joined to sheet-metal assemblies or facing salt spray.

228 MPa · 60 HB

Machinability

Aluminum 5083-H111

The shipbuilding aluminum: highest-strength weldable 5xxx for marine and cryogenic structure.

290–320 MPa · ~75 HB

Machinability

Cast Tooling Plate

MIC-6 Cast Aluminum Plate

The flatness specialist: stress-relieved cast plate that will not move when you machine it.

~166 MPa · ~65 HB

Machinability
