How to forge brass

Are you aware that the forging prowess of blacksmiths is not limited to steel alone? Let’s find out how to forge a brass, which is one of the most common materials blacksmiths use for projects.

Blacksmiths are capable of forging several other materials aside from steel. Brass is also one of the crucial materials usually forged by blacksmiths. Brass is an alloy of copper and zinc.

As much as the necessary forging procedures of blacksmiths are similar, the technique can slightly vary with different materials. The difference in the physical and chemical properties of these materials accounts for the variation. These properties include boiling and melting points, elasticity, resistance, tensile strength, and so on. 

The knowledge of these materials and their properties provides the basis for the suitable technique for their forging process. Brass is not a strange material to blacksmiths. They often employ it in the creation of some of their most beautiful arts. 

However, the forging procedure of brass is slightly different for that of steel. The difference is as a result of the dynamic properties of brass. These properties include high strength, thermal elasticity, melting and boiling points, and so on. 

If you are a professional blacksmith or are aiming to forge brass for the first time, you don’t have any reason to worry. The following step can serve as a guide to the forging procedures of brass.

Essentials

The essential materials for forging brass can vary slightly depending on specific projects. Nevertheless, some specific tools are crucial for the general procedures of forming brass. These essentials include;

Forge/heat source

Hammer

Anvil

Tongs

Cutter

Instructions on How to forge brass

Step 1: Get Your Materials

First off, you should understand that the material in this concept is brass. The materials you are getting are dependent on the aim of the project. You can either make a single brass stock [finer product] from scarps or pieces. 

Alternatively, you might want to forge brass into supplies for other uses such as knives and other tools. Regardless of your intention, ensure that you are getting the right material for your project.

Step 2: Slug Heating

Slug heating is a very crucial part of the forging process of brass. Slug heating aims to improve the quality of the material as well as the possible outcome. However, this step must be done carefully by ensuring adequate regulation of the temperature.

Note:

  • Ensure that the brass material is not too cold to avoid overfilling the die cavity. 
  • Also, it should not be too hot to avoid coming up with a porous surface.

Step 3: Forging

 Now it is time to go to the forging process properly. This step aims at heating the material to a workable temperature where you can create what you have in mind. You should be aware that the technicality of this part is dependent on what you intend to forge. 

Also, you can get to improve the mechanical and physical properties of the materials. You can either make the materials into the final supplies you want at this stage or transform it into suitable material for other processes.

Quick Steps

  • Heat the material to a suitable temperature. The appropriate temperature might vary with the intended purpose of the material. The temperature range is usually between 1,300-1,500℃.
  • You should expect it to be malleable at this temperature. Move on to forge what you intend using suitable techniques. If you want to make brass material that can be useful for further processes, then compress it. 
  • The latter is mostly an industrial process. Therefore, you can consider any open die forging, close die forging, or ring rolling forging techniques. 
  • You might have to re-heat the brass as the forging process proceeds. But if you are quick enough, there might be no need.

Step 4: Trimming

You are just fine-tuning whatever you made in step 3 above and cutting off all excesses. However, it would be best if you were careful not to have too many extras. Too many excesses will only mean you are creating a higher amount of scrap.

Step 5: Finishing

There is usually no big deal on the finishing process for brass. A good brass has an appealing outlook on its own. And if you carry out the above steps correctly, the need for specialized finishing should be mitigated. 

However, the critical primary finishing is getting rid of the surface oxides. It is usually done by immersing the parts of the brass several times in unique solutions.

FAQs on How to forge brass

Question

What are the advantages of forging brass?

First off, you must be aware that brass is mostly useful for decorative purposes. They are suitable for this purpose because they have appealing outlook and malleable properties. They are also valuable for the production of several other tools and supplies.

Question

What are the critical properties of brass?

Brass contains copper and zinc. Just like every other material, brass also has properties that make it dynamic and useful. These properties include resistance and dimensional tolerance, high strength, thermal adaptability, and so on.

Question

What are the components of brass?

Brass is primarily composed of two different materials. Each of these materials can vary in percentage; thus, having a significant impact on the brass’s eventual properties. The two dominant materials in brass are copper and zinc. 
These two components can be combined differently to give hybrid properties to suit the intended purpose.

Question

Is brass a pure metal?

No. Brass is not a pure metal. It belongs to a group of metal known as alloys. The metal alloy is the resultant metal from the combination of two metals. In this case, brass is an alloy of zinc and copper.

Precautions

Precautions are one of those things you should never neglect while forging brass. These precautions will improve your output and mitigate the possibility of accidents. These precautions include; 

  • Ensure proper ventilation of your workplace.
  • Pay attention to the temperature of the materials throughout the forging process. 
  • Use gloves, eyeglasses, and other blacksmithing safety gear.
