Copper and Brass Extrusions: How Are They Manufactured?


There are a number of methods to work a metal into different forms. One of the most widely used methods is extrusion. This involves pressing a workpiece into a die to obtain a material with a certain desired cross-section. Builders and suppliers prefer extrusion to other techniques because it is quicker and the output is much denser and smoother.

How Extrusion Works

The process starts with the preparation of the workpiece, which is a metal block of standard size. Depending on the desired result, the workpiece is either heated or kept at room temperature before being fed into the die. As soon as the billet is fitted inside the container, the plunger is placed on the opposite end and made ready to push the billet towards the die. The compressive force used to press the billet is enough to extrude the billet by way too low to affect the whole container.

Unlike casting, which involves smelting the metal, pouring it into a mold, and cooling to cure, the product of extrusion is virtually ready for use, unless further heat treatment is required to improve its mechanical properties. Sometimes, the output is stretched to adjust its dimension with the actual desired size and shape. Read more from this article:


How Brass Extrusions Are Made: The Metalworking Process Explained


There are many ways metal can be worked to form a desired shape. You can anneal it, cast it, or even chase it depending on how quickly you want to produce results. When it comes to forming detailed cross-sections, however, the most popular method is extrusion, and it’s easy to understand why.

Continuous. Other methods will require multiple processes, such as formwork construction, melting, and curing to produce a tube. Whereas, extrusion can perform all of those processes continuously. When metal requires hot-working, it is hot-worked right before being fed into the die, and as soon as it comes out of the die, the output becomes almost ready for use.

High production. Because the process is continuous, production is also expected to be high. In effect, you can save tremendous amount of time and money in the long run. Plus, you can double or triple your income in a short span as opposed to the few days of work when you use a more complex metalworking method. Read more from this article:

The Different Techniques for Making Brass Extrusions


Extrusion is a metalworking process that involves forcing a metal inside a die with a different cross section. Due to the compression and force applied onto the inlet, the metal is deformed as it is fed and the different shapes of the brass extrusions are formed. Most people already know the gist of the extrusion manufacturing, but what many don’t know is the different types of extrusion processing. Here are the four major types of extrusion and how each of them works:

Direct Extrusions. Also known as the forward extrusion, this process involves having the billet move in the same direction as the ram and punch. A lot of friction is created between the container and the billet because the billet slides against a stationary wall. This method requires a lot of force to make the final product. To prevent oxidation, a dummy block with a slightly smaller diameter is used during hot extrusion. This process is best used for creating solid circular and non-circular extrusions as well as hollowed tubes and cups.

Indirect Extrusion. Also known as backward extrusion, indirect extrusion occurs when the punch moves in the opposite direction of the billet. There is less friction because no relative motion between the billet and container happens. This also means that less force is required during the manufacturing of extrusions. Although indirect extrusion uses less energy, the process cannot produce long extrusions. Many manufacturers actually combine both direct and indirect extrusion to create final products of the best quality. Read more from this article:

Pieces of Newly Formed Brass Extrusions and Other Metal Extrusio

Brass has a classy and elegant look that not many other alloys can come close to. Ever since its amazing properties were discovered, this metal has been used for various applications. Everything from coins to architecture, you’ll find traces of brass. This is mainly because apart from being strikingly appealing, brass is also durable and malleable. It has all the necessary qualities for aesthetic and practical uses.

Most brass pieces in the past were only available in plain sheets, tubes, or pipes. With the invention of new metal forming techniques and other advances in metallurgy, most complex designs for brass pieces are already achievable. Whether you need a super-thin sheets or exceedingly complex brass extrusions, you’re very likely to achieve your goal.

What is extrusion?

Extrusion is a metal working process in which a metal, in this case brass, is melted and then pushed through a certain die to create a fixed, cross-sectional profile. A lot of metalworkers are choosing this process because it’s much faster and it is capable of making the most complex cross-section designs while using very brittle materials. Plus, the resulting extrusions usually have a beautiful smooth surface finish that is valued from a design point of view. Read more from this article:

Metal Extrusions for Aesthetic Enhancement and Industrial Applications

Most metals used for industrial purposes are dense and hard. They are mined as ore, melted and refined to remove impurities, and solidified to achieve the hardness required by their intended applications. Sometimes, they are alloyed with other metals to create even stronger and more durable materials. How they are manufactured into bars, sheets, and modified shapes, however, is a completely different process, called metal forming.

Different Metal Forming Methods

Metal forming is the process of shaping metal through mechanical deformation. It doesn’t involve the use of chemicals, only high loads and stresses. There are two main categories: one is compressive forming in which the primary means of deformation is uniaxial or multiaxial compressive loading, and the other is tensile forming, which relies on pulling forces. Some specialized metalworking processes require a combination of both, while others require different versions of the force applied on them, including bending and shearing.

Of the two categories, compressive forming is the more commonly used one, as it can be performed in many ways, including rolling, extrusion, die forming, forging, and indenting. All of these techniques involve pressing metal with a heavy load to turn it into specific shapes. Among these compressive forming techniques, the most unique and particularly efficient is extrusion. Manufacturers in need of high production volumes in the shortest time possible should opt for this option. Read more from this article:

Brass Extrusions: Understanding How Extrusion Works and Why It Is a Lucrative Molding Option

Brass Extrusions Produce the Best Tubes, Pipes, and Machine Parts

Before the metal parts in your car engine, plumbing system, or even the device where you’re reading this from became the intricate construct that they are now, they first underwent a series of arduous processes. Perhaps the most critical of these is molding, as it is in this stage where a metal’s final form is decided.

There are numerous methods for molding metal but arguably the most efficient is extrusion. This method involves forcing a piece of metal (also called “work piece”, at least in metalworking) into a die, a tool that has holes with cross sections smaller than the work piece. The portion of the work piece that is allowed to pass through the die becomes the final product, called extrusion.

Benefits of Extrusion

Molding metals is an expensive business. Casting (one of the costliest methods), for instance, involves melting metal and pouring it into a mold. To achieve this, tremendous amounts of fuel are required to keep the blaze in the furnace going, and there’s a constant need for a new mold. Extrusion, on the other hand, reduces if not completely eliminates the need for both metal melting and mold production. No extreme heat is needed; just enough heat to force the metal into the die, and a special kind of compressor. The die is pretty much reusable so manufacturers don’t have to keep making new ones.

Brass Extrusions—When Casting and Other Methods Just Won’t Work for You

Brass Extrusions Are Made with Precise and Accurate Cross-Sections

Metal products, such as tubes and shafts, can be manufactured in a number of ways. Perhaps the most popular method is casting, which involves pouring liquid metal into a form that contains a hollow cavity. Although effective, this method can be costly and time-consuming since it consists of several processes, including melting and curing.

Those who are looking for ways to cut down on manufacturing cost should consider a method that produces results fast. One in particular is extrusion. This method involves pushing a metal through a die of a desired cross-section. There’s no melting, curing, and other extra processes that need to be done. Once the extrusion comes out of the other end of the machine, it’s ready for use. Read more from this article:
