Cast iron aluminum pipe wrenches are essential elements for any professional or DIY plumber. The secret to good plumbing is choosing the perfect pipe wrench, which is determined by mostly what it is made out of.
A pipe wrench is a tool used to grip, loosen, and tighten, as the name suggests, pipes and fittings. Pipe wrenches take the design of Stillson, who patented the first pipe wrench back in 1896. They have adjustable upper jaws which grip a pipe’s surface.
Due to innovation, the traditional steel pipe wrenches have now been improved to pipe wrenches made out of aluminum and cast iron. Each of these wrenches has its advantages over the other one. Therefore, in this article, we will critique whether to go for the aluminum or cast iron pipe wrench.
Overview Of Aluminum Pipe Wrench
It may be difficult to distinguish one pipe wrench from another. But when you take a closer look, you can identify the materials used to make them and their various sizes. There are three types of pipe wrenches; the straight pipe wrench, the end pipe wrench, and the offset pipe wrench.
The cast iron aluminum pipe wrench is what we will focus on. An aluminum pipe wrench is a current improvement that has been established in the plumbing world. The traditional pipe wrenches were and still are very heavy and bulky; for example, the cast iron pipe wrench.
The primary distinguishing feature of an aluminum pipe wrench is its lightweight. It is forty percent lighter than a cast iron pipe wrench which is a remarkable weight difference. And it still does the same work as any other pipe wrench.
This makes it very convenient to carry around and comfortable to use especially for people like plumbers who have to use it now and then.
It has two serrated jaws where the upper jaw is adjustable to fit various sizes of a pipe. Its teeth will only hold when the wrench is turned in one direction. It also has a long pipe wrench handle.
The jaws enable the wrench to grab the pipe’s surface and provide the required grip. The pipe wrench handle provides stability for turning particularly tight fittings. The pipe wrench handles are cushioned or covered with rubber for comfort. The longer the pipe wrench handle, the greater the leverage.
The jaws and teeth are made out of steel to provide a reliable grip and maximum durability, while the rest of the body is made out of aluminum. The aluminum body makes them light and easy to move around with.
They are available in sizes ranging from 9 to 60 inches in length of the pipe wrench handle. They are very easy to use because they have self-cleaning threads and easily and instantly changeable hook and heel jaws.
In terms of price, the aluminum pipe wrench is quite expensive compared to the cast iron pipe wrench. On the other hand, it weighs only 3 lbs which makes it very much lighter than cast iron pipe wrench.
One is left to decide on whether to consider weight over price i.e. aluminum or cast iron pipe wrench or vice versa.

Overview Of Cast Iron Pipe Wrench
The cast iron wrench is one of the traditional types of pipe wrenches. It is made out of iron all around except for its jaws and teeth, which are galvanized with steel to provide enough grip.
Cast iron wrenches are very heavy, weighing twice as much as aluminum pipe wrenches. They offer the needed torque and durability for heavy-duty plumbing jobs where aluminum pipe wrenches can not be used due to wear and tear.
They are much stronger and stiffer than aluminum pipe wrenches. The jaws adjust from 1.5 to 5 inches. They can withstand deformation, and this makes them very durable and long-lasting. The head has a flat surface, and the pipe wrench handles are covered in plastic sheaths for comfort.
The cast iron pipe wrenches are preferred in smaller sizes due to their heavy weight. For larger sizes, aluminum wrenches are the most suitable.
