Methods to Make Copper Forgings

Metals have widespread usage due to their properties. Copper is one of the elements widely used in the industry. That’s because of its characteristics which you can find out about on this site. This metal is suitable for all types of processing.

Copper is a highly ductile metal, and it possesses low thermal conductivity. The heat generated during the process doesn’t radiate out from the metal, which further increases the life of the component. These ductile and antimicrobial elements show resistance to corrosion and external factors too.

There are many copper products in the market. They can be used in various industries, as their range is pretty vast. Some of these are plumbing pipes, tubs for faucets, all kinds of fittings, fixtures like bathtubs and showers, carvings, railway couplings, locks, knobs, valves, and so on.

Another feature that makes copper forgings popular among various industries is that they can exhibit different bending characteristics. Bending features provide different strength levels, and thus various types of products.

About Forging

Forged metal parts are obtained from one piece of metal processed by hands. Forging is the oldest method of material processing.  Nowadays, it’s performed in different ways, depending on the requirements of the final product. Commercial forgers use powerful pressure machines and modern furnaces. 

The metal forging process is a spatial design of metal and can be done in two different methods. Materials are formed by deformation without changing their internal structure. What makes the difference between them is the operating temperature.

Forging methods are cold material deformation and complete thermal deformation (hot forming). Both techniques are commonly used. Each of them has its good sides, depending on desired outputs. The choice will depend on the type of business that needs copper forgings. 

The Art of Forming Metal

The primary difference between cold and hot forging is temperature. Another thing that differs is the method of heating. While hot forging uses thermal energy, cold forming uses mechanical energy. Cold forge steels and bars are heated at room temperature. Hot forging continues the process in a fire.

Using either type of procedure, manufacturers can process any type of metal. Examples of these are stainless steel, aluminum (using austenitizing), and copper. Many things will affect the choice of material and forming method.

Cold Casting

Cold forming is a popular machining process, as it’s less expensive than other methods. It’s preferred when it comes to soft metals like copper. A tooling furnace, used to turn the metal into a large sheet, is usually run at low temperatures. 

The forgers struck a piece of metal with a mallet, causing its solid form more plastic. This processing at ambient temperature has high precision in shape and dimension. It’s doable on smaller surfaces. It’s suitable for automatic production as there’s no need for finishing work.

Cold processing makes improvements in the strength of copper. It also improves reproducibility and material dimensional control. This procedure can be combined with heating, which serves to remove residues after hammering. But even with no finishing, copper forgings made by cold forming are durable, strong, and adapted to any need. 

Hot Metal Forming

Hot forging is an easier and faster method than the cold one. Since heat is used in the process, it leads to consistent results and high-quality outputs. It is the most widely used process for metals and alloys in the entire world.

Materials are hammered at a high temperature. The hot forge method uses heating until the metal becomes rigid. The heat prevents strain hardening of the copper during deformation. The next step is cooling and then forming desirable shapes. 

The major advantage of hot casting is that it allows for a more complex and detailed finish. It allows for increased strength when compared to ordinary forged pieces. Another difference is that the finished copper forgings will have a bit different composition than the raw material. That makes them easier for shaping.

Forging doesn’t change copper’s features too much, but only its shape. But subtypes of metal forming under the heat and pressure improve some of the basic elements of copper. Both cold and hot forging boost the flexibility and strength of this metal.
