Due to its versatile nature, aluminum is widely used in metalworking industries. It comes in various thicknesses, which are measured in gauges. So, among various thicknesses, how thick is 22 gauge aluminum? This question confuses many people. As a result, they cannot decide whether this thickness is suitable for their project or not.
Remember, when the thickness of aluminum is changed, its properties also change. So, knowing the exact thickness of any aluminum sheet is very crucial. Do you also get confused about 22 gauge aluminum thickness? Fret not! In this article, I will reveal the truth about the thickness of 22-gauge aluminum. So let’s get started!
What is a Gauge in Metal Working?
A gauge is a unique measuring unit in metalworking. It represents the thickness of any metal. However, you may be surprised to know that the value of the gauge is inversely proportional to thickness. How? Let me explain. Suppose you buy two aluminum sheets. One is 30 gauge thick, and the other is 24 gauge thick.
Which one is thicker? A 24-gauge plate is thicker than a 30-gauge plate. So, when you need a thinner metal plate, you should go for one with more gauge value. After learning the gauge concept, you may wonder why metal thickness is measured in gauges. Why is it not measured in inches or millimeters? Right?
There are several reasons behind its use. The first significant cause is its convenience in industries. Measuring in millimeters or inches requires calculating decimals, which is not easy. However, a gauge is a simple measuring unit that makes it easy for professionals to measure thickness.
Another reason is that the gauge clarifies the comparison between different metals.
For example, an 18-gauge aluminum sheet is thinner than an 18-gauge stainless steel sheet. So always remember that gauge value varies from material to material. A 14-gauge copper plate will have a thickness different from a 14-gauge stainless steel plate.
How Thick is 22 Gauge Aluminum?
22 gauge aluminum is 0.025 inches thick and 0.64 millimeters thick. These values in inches or millimeters are not exact. They can vary slightly with manufacturing standards. This thickness level of aluminum is considered lightweight. Due to this, it is used where flexibility and easy handling are significant concerns.
A 22-gauge aluminum plate or sheet is easy to handle and cut. However, due to its thinness, you may worry about its functionality. But remember, although the 22-gauge aluminum is thinner still, it does not compromise its properties. You can find all the properties of aluminum, such as corrosion resistance, thermal conductivity, and shine.
As I said above, gauges are inversely proportional to thickness. So, if you are looking for a thinner option than 22-gauge aluminum, 24-gauge aluminum is better suited. Do not mix this thickness with other materials. In the case of other materials, 22-gauge will have different thickness levels.
Tools to Measure 22 Gauge Aluminum Thickness
How does someone know that aluminum is 22 gauge thick? Here, some special tools come into sight. These tools accurately measure the thickness and ensure you get an aluminum sheet with the right thickness. Let’s discuss those tools in the section below.
1- Micrometer
Micrometers are the most accurate tool. It can measure up to thousandths of an inch. Therefore, it is the best tool for measuring a 22-gauge aluminum sheet. It consists of a spindle and an anvil. When the aluminum sheet is kept between the spindle and the anvil, it provides readings on the digital screen.
2- Calipers
Caliper is another tool for measuring the thickness of 22-gauge aluminum. It may have a simple design that works manually or a digital system. It consists of two jaws. When a metal plate is placed between these jaws, it measures the thickness. But keep in mind that it is less accurate than a micrometer.
3- Gauge Thickness Chart or Tool
It is a quick tool that confirms the thickness of any metal in gauge. It consists of pre-set slots. If you want to verify that your aluminum plate is 22 gauge, put your plate in this tool. It will show you whether or not your aluminum plate has a 22-gauge thickness.
Quick Highlight: The above-mentioned tools vary in terms of how they work. However, their functionality remains the same: measuring the thickness of aluminum sheets. You can use any of them to measure the thickness of the sheet.
Properties of 22 Gauge Aluminum
Knowing the properties of 22 gauge aluminum before you buy it is crucial. After learning its properties, it will be easy to decide on its selection. So, let’s take a short glimpse at its properties.
1- Lightweight
At gauge scale, 22 gauge is lightweight. So, this property of 22 aluminum makes it stand out. Its lightweight is beneficial in many fields. For example, in automotive parts, electronics, and aerospace industries, 22 gauge aluminum is widely used. However, its lightweight does not make it weak. It is strong enough for everyday uses.
2- Corrosion Resistance
As you know, aluminum is naturally corrosion-resistant. This is due to the formation of its oxide layer. When aluminum is exposed to oxygen, it forms an oxide layer. This oxide layer prevents it from further corrosion. So, this property is also retained in the 22 gauge aluminum plates. You can use these plates in a moist environment.
3- Malleability and Flexibility
22 gauge aluminum is highly malleable. Its tensile strength is very high. It can be easily bent and changed into wires or sheets without breaking. This property makes its usability familiar for automotive and construction. Moreover, its flexible nature allows you to handle it easily. Its fabrication becomes very easy due to this property.
4- Aesthetic Appearance
22 gauge aluminum has naturally gained its shine, making it suitable for decoration pieces. Moreover, aluminum can be anodized, further enhancing its aesthetic appearance. Due to its smooth and delicate surface, it is widely used in craftwork, appliance casing, and artwork.
Is 22 Gauge Aluminum Right for Your Project?
The answer is: it depends! If your project needs lightweight and flexibility, this is best suited. Moreover, you can also use it in outdoor spaces due to its corrosion resistance. In particular, if your project demands smoothness, you should not ignore 22-gauge aluminum.
But remember, there are always two sides to a picture. So before choosing this option, you should also consider its flaws. For example, it is less strong due to its lightweight. Therefore, it can be challenging to manage heavy projects. Furthermore, its shine and smooth surface can also prove a challenge.
If you use it in outdoor crowded and traffic-rich places, it will lose its shine. Due to its delicate nature, there is a higher chance of dents. Lastly, I recommend using it in your project if it does not require heavy-duty performance. For gentle usage, the 22 gauge aluminum sheet offers optimal performance.
Frequently Asked Questions
How does 22-gauge aluminum compare to steel of the same gauge?
22 gauge aluminum is thinner and lighter than 22 gauge steel. This is due to the nature of metal. However, 22-gauge aluminum is not suitable for heavy-duty operations. At the same time, 22 gauge steel can efficiently perform those duties.
Can 22-gauge aluminum be easily worked with?
Yes, 22 gauge aluminum is easy to work with due to its lightweight. Moreover, due to its malleable and flexible nature, it can be easily bent and cut.
Can 22-gauge aluminum withstand high temperatures?
Although 22 gauge aluminum is thermally conductive, it cannot withstand high temperatures. This is due to its low melting point, which is about 660°C.
Conclusion
In short, gauge is a term used for measuring the thickness of metal sheets. Remember, metal sheets can have different gauge thicknesses. In this article, I have discussed the thickness of 22-gauge aluminum. In inches, it is 0.025 inches thick, and in millimeters, it is 0.64 mm thick.
Therefore, it is used where flexibility and lightweight matter. However, other properties of 22 gauge aluminum are corrosion resistance, malleability, and smoothness. Due to these properties, it is used for decorative purposes and other industries such as automotive. Lastly, you should select this thickness according to the nature of your project.
