Aluminum Angle – The Ultimate FAQ Guide

How To Cut Aluminum Angle?

You can follow the given steps to cut aluminum angle in no time:

  • To cut aluminum angle, you have to measure the length you want to cut, then mark it. Use a T-square for accuracy as you measure the length.
  • Next, you lubricate the blade to prevent it from attaching to debris and grabbing the aluminum angle as you cut it.

This can lead to severe injuries, such as losing your finger. Also, lubricating prevents overheating of the blade.

  • Use safety goggles to prevent small pieces from entering your eye when cutting aluminum angles.
  • Next, you could use different cutting saw as the miter saw, chop saw, or band saw to cut your aluminum angle.
  • After cutting the aluminum angle, you use a sanding disk to sand off any excess length.

What To Use To Cut Aluminum Angle?

  •    Use a Chop Saw:

A chop saw is a type of circular blade. A chop saw is used precisely to make straight cuts on aluminum angles.

To cut aluminum angle with a chop saw, you start by preparing the chop saw blade.

It would be best to use a metal cutting blade made for non-ferrous metals.

Next, you lubricate the blade so it doesn’t grab the aluminum angle, leading to serious injury.

Next, you clamp the aluminum angle to hold it in place while cutting it.

 Now, slowly lower the chop saw on the aluminum angle to cut it.

Remember to use a face shield to prevent aluminum pieces from entering your eyes or nose.

  • Use a Bandsaw:

To cut aluminum angles using a band saw, you start by measuring and marking the length you want to cut. Do this for both legs of the aluminum angle.

Use a T-square to make your measurements accurate.

Also, when cutting aluminum angles with a band saw, you should cut outside the line to avoid cutting into the part you want to use by mistake.

Next, you run the aluminum angle through the band saw to cut it.

Finally, take the aluminum angle to a sanding disk to remove excess length. Use a T-square to position your aluminum angle in place while you sand it.

  • Use a Miter saw:

cutting aluminum angle with a miter saw

cutting aluminum angle with a miter saw

A miter saw is used precisely for angled and beveled cuts.

To cut the aluminum angle with a miter saw, you start by preparing the blade. Use a carbide-tipped blade.

Not all carbide-tipped blades are suitable for cutting metal, so pick a non-ferrous blade suitable for cutting metal.

Next, use a C clamp to secure the aluminum angle while being cut.

Next, lubricate the blade and the aluminum angle part to be cut.

Lubricating will help prevent the blade from grabbing the aluminum angle, which is dangerous.

Finally, lower the miter saw slowly on the aluminum angle to cut it.

You should always follow safety guidelines when operating a miter saw.

Always use a face shield to protect them from the small pieces of aluminum.

What Sizes Does Aluminum Angle Come In?

Aluminum angle comes in a variety of sizes. For example, the length of both legs of the aluminum angle can range from 3/4, 1, 1 1/4, 1 1/2, 1 3/4, 2, 2 1/2, 3, 4, 5, 6, and 8.

The thickness of the aluminum angle ranges from 1/2,1/4,3/8,1/8, 3/16, and 5/16.

Different sizes of aluminum angle

Different sizes of aluminum angle

The overall size and weight will be different for aluminum angle, because the length and thickness for produced aluminum are various.

How Do You Measure Aluminum Angles?

All aluminum angles have two legs. You measure aluminum angles by measuring the length of both legs and their thickness.

For example, you measure the width of each leg, then their overall length and thickness.

How Is Aluminum Angle Made?

When extruding aluminum, let them form angle-like shape with tow legs, call aluminum angle. It is also referred to as angle aluminum or L angle aluminum.

In general, there are two kinds of aluminum angle mainly like below:

  • Architectural aluminum angle

Architectural aluminum angle is a 6063 series aluminum alloy. It is made of Silicon (0.2% †“0.6%) and Magnesium (0.45% †“0.9%) as the main elements of the alloy.  

Architectural aluminum angle has a 90 degrees angle on both the inside and outside of the angle.

The architectural aluminum angle can be used for window constructions and furniture constructions. It can also be used for architectural trims.

How Thick Is The 11 Gauge Aluminum Angle?

An 11 gauge aluminum angle has a thickness of 0.091″ for 2.31 mm. It also has a thickness tolerance of ± 0.0045″.  

How Much Weight Can Aluminum Angle Hold?

Aluminum angle’s weight carrying capacity depends on factors such as the metal’s length and thickness and the location and type of both load and support.

For example, if the supports are fixed at both ends, then the weight of the load will be concentrated at the center.

On average, it is estimated that aluminum angle can hold up to 10,000 to 75,000 pounds.

Also, the weight carrying capacity of the aluminum angle depends on the series of aluminum used to make it.

The thickness of the diameter of the aluminum angle also affects the amount of weight it can carry.

How Strong Is Aluminum Angle?

The strength of an aluminum angle mostly depends on the metal it was made from.

But, other factors like length and thickness can affect the strength of an aluminum angle.

But in general, aluminum angles have a tensile strength between 10,000 to 75,000 psi. This strength makes aluminum angles strong enough for many heavy load applications.

How To Bend Aluminum Angle?

Aluminum angles can be bent into different shapes for different applications.

For example, roll bending of aluminum angle is used to bend the metal in a circular shape. This can be used for applications such as handrails.

Roll bending is a type of bending method that uses three rollers to bend the aluminum angle.

Also, aluminum angles can be bent to 90 degrees for applications such as window frames.

These angle bends are created by cutting or notching a part of the aluminum angle before bending it to its desired shape.

For example, a 6061 aluminum angle with a density of 2.72, a length of 600mm, a width of 10mm, a height of 10mm, and a thickness of 5mm will weigh 0.082 kg (81.6g).

How To Cut 45 Degree Angles In Aluminum Angle?

The best way to cut 45 degrees angles in aluminum angle is to use a miter saw.

Follow these steps to cut 45 degrees angles:

  • First, you must select the right blade for cutting the aluminum angle. Use a non-ferrous blade cutter.
  • After picking the right blade, you must hold the aluminum angle in place with a C clamp.

The C clamp prevents the aluminum angle from shaking while you cut it.

If the aluminum angle is shaking as you cut it, you might miss the 45-degree angle or get bad cuts.

  • Next, you lubricate the blade and the area you want to cut. Lubricating reduces friction stops the blade from grabbing the aluminum angle.
  • Next, slowly lower the blade on the aluminum angle to cut it.
  • After cutting it, you can use sandpaper or a file to remove sharp edges and burrs from the aluminum angle.

You can also use a hack saw or a band saw to cut aluminum angles.

But the miter saw is the best to use because it offers a clean and straight angular cut.

Remember not to cut aluminum angle when standing on both legs in a V shape; instead, cut it when standing on one of its sides in an L shape.

You must also wear a face shield to protect your eyes, nose, and mouth from small aluminum pieces when you are cutting it.

How To Cut Aluminum Angle With Chop Saw?

A chop saw is a circular blade used to make precise straight cuts on an aluminum angle.
