0.063 Aluminum Sheet

Why .063 Is a Popular Choice

0.063 Aluminum Sheet in Different Units

Buyers sometimes need this thickness converted for international orders or spec sheets.

Unit	Value
Inches	0.063
Millimeters	1.6
Gauge (approx.)	14 gauge
Micrometers	1600

Note that gauge numbers can shift slightly depending on the standard used, so millimeter or decimal inch measurements are the safest way to confirm an exact match.

Alloy Options at 0.063 Thickness

Alloy choice changes strength, corrosion resistance, and cost, even when the thickness stays the same.

Alloy	Temper	Best For
3003	H14	General fabrication, trim, tanks
5052	H32	Marine parts, fuel tanks, higher strength panels
6061	T6	Structural brackets, machined parts
1100	H14	Budget fabrication, reflective panels
5083	H32	Heavy-duty marine and structural use

3003 in H14 temper is the most commonly stocked option at .063 thickness, since it balances cost and formability for general shop work.

Weight of 0.063 Aluminum Sheet

Weight helps with shipping estimates and structural load calculations.

Alloy	Weight (lb/sq ft)	Weight (kg/m²)
3003	0.90	4.39
5052	0.91	4.44
6061	0.90	4.39
1100	0.90	4.39

Weight stays fairly close across alloys at the same thickness, since aluminum density does not change much between common grades.

Standard Sheet Sizes

.063 aluminum sheet ships in several standard sizes, with custom cuts available on request.

Width (in)	Length (in)
24	48
36	96
48	96
48	120

Coil Option

Coil form is also available at .063 thickness for buyers running slitting or roll-forming lines, sold by coil weight rather than sheet count.

Product Types

.063 aluminum sheet comes in several finish and form variations, suited to different jobs.

Mill Finish 0.063 Sheet

Painted 0.063 Aluminum Sheet

Coated with a baked-on paint finish, often PE or polyester-based.

• Wide color range for trim, panels, and signage
• Added UV protection over bare mill finish
• Slightly higher cost than mill finish

Diamond Plate 0.063 Sheet

Perforated 0.063 Sheet

0.063 Aluminum Coil

Continuous roll form for roll-forming and slitting operations.

• Sold by coil weight, not sheet count
• Common alloy and temper range matches flat sheet
• Suited to high-volume fabrication lines

.063 vs .050 vs .080 Aluminum Sheet

Thickness comparisons help buyers pick the right gauge for their project.

Thickness (in)	Rigidity	Common Use
.050	Lower	Light panels, covers
.063	Moderate	General fabrication, brackets, panels
.080	Higher	Structural parts, heavier equipment panels

.063 sits between these two options, giving more strength than .050 without the added weight and cost of .080. It is often the default choice when a part needs to hold its shape under moderate stress.

Choosing the Right Thickness

→ Building a lightweight cover or panel? .050 keeps weight and cost down. → Making a general-purpose bracket or panel? .063 offers the best balance of strength and weight. → Need extra rigidity for structural parts? Step up to .080 or thicker. → Working with saltwater or marine exposure? Choose 5052 alloy regardless of thickness.

3003 vs 5052 at 0.063 Thickness 0.063 Aluminum Sheet

These two alloys are the most common comparison at this gauge.

Factor	3003 (.063)	5052 (.063)
Strength	Moderate	Higher
Corrosion resistance	Good	Excellent, including saltwater
Formability	Very good	Good
Typical cost	Lower	Slightly higher
Common use	General fabrication	Marine parts, fuel tanks

5052 wins where higher strength or saltwater exposure matters. 3003 remains the more cost-effective pick for general shop fabrication at this thickness.

Applications

Why Fabricators Choose 0.063 Sheet

Easy to Work With Standard Tools

Shears, brakes, and drills handle .063 sheet without needing heavy-duty equipment.

Balanced Strength-to-Weight Ratio

Thick enough to resist denting and flexing in light-duty use, without adding unnecessary weight.

Wide Alloy Availability

Most alloys, from 3003 to 6061, are stocked at this thickness, giving fabricators flexibility to match material to the job.

Common Stock Size

Because .063 is a standard gauge, lead times stay short and pricing stays competitive compared to less common thicknesses.

Packaging and Delivery

Technical Conversion & Decimal Equivalencies

Understanding 0.063 inch thickness in standard measurement units helps buyers match blueprint callouts with global mill standards:

Imperial (Decimal)	Fractional (Approx.)	Metric (mm)	Gauge Standard (Brown & Sharpe / AWG)	Approximate Unit Weight
0.0630′′	1/16′′	1.60 mm (Nominal)	14 Gauge	≈0.887 lbs/ft2 (4.33 kg/m2)

Forming, Bending & Minimum Bend Radius Parameters

At 0.063′′ thickness, bend performance depends directly on alloy choice and temper condition. Using an incorrect inside bend radius (R) causes orange peel or cracking along the bend line.

5052-H32	1.0t−1.5t (0.063′′−0.095′′)	Very Good	Preferred structural grade; align bend perpendicular to rolling grain.
6061-T6	2.5t−3.5t (0.156′′−0.220′′)	Fair / Moderate	Requires larger bend radii; anneal or warm up if tight bend is needed.
