Aluminum sheet metal is a total crowd-pleaser in tons of industries. It’s bendy, tough, and super light. A big thing to wrap your head around is its gauge and thickness. This guide walks you through what gauges are, how they connect to thickness, the different thickness options out there, and the tools you can grab to measure them just right.
What’s This Gauge Thing?
What Gauge Is
Gauge is just a quick way to say how thick a metal sheet is. For aluminum, a bigger gauge number means a thinner sheet. It’s a simple system that helps folks making or buying sheets pick the perfect size for their projects.
Take the 1050 aluminum sheet—it’s got over 99.5% aluminum, so it bends like a dream and doesn’t rust. It’s also awesome at carrying heat and electricity. That makes it great for jobs where you need something thin but strong.
How Gauge Links to Thickness
Gauge numbers aren’t the same for every metal, you know? For aluminum, each gauge tells you how thick it is. That thickness is listed in inches or millimeters.
Take a 16-gauge sheet: it’s about 0.0508 inches thick. Or in metric, roughly 1.29 mm. A 20-gauge sheet? Thinner – around 0.032 inches or 0.81 mm.
Aluminum sheets come in all kinds of thicknesses. It really depends what you need for your project. Think about 1350 aluminum coils. They can be crazy thin, like 0.1 mm. Or super thick – up to 500 mm. That’s why they’re useful for so many things.
Thickness Options You’ll Find
Aluminum sheets come in a whole range of thicknesses to fit whatever you’re working on:
- Thin Sheets: These are really slim, from 0.1 mm to 2 mm. They’re perfect for electronics, packaging, or decorative stuff.
- Medium Sheets: These are a bit beefier, from 2 mm to 6 mm. You’ll spot them in construction or transportation projects.
- Thick Sheets: These are the heavy hitters, over 6 mm and sometimes up to 500 mm. They’re awesome for big stuff like ships or airplane parts.
The 5251 aluminum sheet, for instance, goes from 0.1 mm to 500 mm. It’s often used for structural bits in trains or aerospace gear.
Tools to Measure Thickness
Getting the thickness of a sheet spot-on is super important to make sure it works for your project. Here’s what you can use:
- Micrometers: These are fantastic for super precise measurements.
- Calipers: They come in digital or manual versions. They’re great for checking outside and inside sizes.
- Ultrasonic Gauges: These use sound waves to measure thickness without messing up the sheet.
- Gauge Charts: These are handy tables that show what gauge number equals what thickness.
Each tool shines in different situations, depending on how exact you need to be or what you’re working on.
The 5059 aluminum sheet is a great example. It's strong yet surprisingly lightweight. This comes from having just the right thickness. You'll find it used in important applications. Think LNG tanks, gas cylinders, ships, and tank trucks. Understanding gauge and thickness helps a lot. It lets you choose the best material for your projects.
What Aluminum Sheets Are Used For
Thin Sheets
Cars and Airplanes
Thin sheets, from 0.1 mm to 2 mm, are a big deal for cars and airplanes. They’re light but tough as nails. The 5182/6016 aluminum plates are used for car doors because they’re strong and don’t rust. In airplanes, thin sheets make parts where keeping weight low is a must, but safety can’t take a hit.
Electronics and Lightweight Things
Electronics folks love thin sheets for phone casings, circuit boards, or heat sinks. The 5252 aluminum sheet is a go-to for phone casings since it’s easy to shape and looks sharp. Thin sheets also pop up in lightweight stuff like signs, packaging, or decorative panels.
Medium Thickness Sheets
Building Projects
Medium sheets, from 2 mm to 6 mm, are super useful in construction. They’re used for building exteriors, roofs, or window frames because they stand up to weather like champs. The 1350 aluminum sheet coils are great for electrical stuff in buildings—they carry electricity well and don’t rust.
Appliances
Things like fridges, ovens, and washing machines often use medium-thickness sheets. They’re strong but easy to work with, so they’re perfect for making tough, lightweight parts. They fit all sorts of designs while staying practical.
Thick Sheets for Big Jobs
Industrial Gear
Thick sheets, over 6 mm, are a must for industrial equipment and machine parts. The 5059 aluminum sheet is super strong but still light enough to handle. It’s used in stuff like LNG tanks, gas cylinders, and tank trucks. These sheets can take on heavy loads and high pressure without blinking.
Ships and Military Gear
For ships, thick sheets are used because they don’t rust in salty water. The 5083 alloy is a favorite for container-grade sheets—they’re light but tough enough for rough seas. In the military, thick sheets go into armored vehicles or protective barriers where strength is everything.

FAQ
Q: What does "gauge" mean for aluminum sheets?
A: Think of gauge as just a way to measure how thick aluminum sheets are. Here's the tricky part: a higher gauge number means thinner metal. Like, 16-gauge is thicker than 20-gauge. It's super helpful when you need the perfect thickness for your work.
Q: How do I figure out thickness from the gauge number?
A: Every gauge number equals a specific thickness. For example:
- 16-gauge aluminum? That's about 0.0508 inches
- Or roughly 1.29 mm
- 20-gauge comes out thinner – around 0.032 inches
- That's about 0.81 mm
Just check a gauge chart. It'll show exact measurements for any number.
Q: Where would I use 1050 aluminum sheet?
A: 1050 sheet is mostly pure aluminum – over 99.5%. Because of this:
- It bends easily
- Won't rust easily
- Carries heat and electricity well
People grab this when they need thin but sturdy stuff. You'll see it in electronics or decorative pieces.
