Characteristics Of Brass
1. Strong processing ability
Brass is one of the metals with high machinability, which is due to the presence of lead in its composition. Brass has processing characteristics such as high feed rate, good ductility, and strong flexibility.
2. Corrosion resistance
One of the characteristics that brass is suitable for processing is its corrosion resistance, which is one of the reasons for the long service life of brass components. In addition, it also makes parts made of brass material suitable for use in liquid environments, but their corrosion resistance depends on the amount of components such as iron and aluminum.
3. Ductility
Brass has extremely high ductility due to its copper content. However, the ductility of this metal is even better than copper. The high ductility of brass makes it the preferred choice for machining projects, as machinists can easily machine this metal into different shapes.
4. Strength and hardness
Brass is not only easy to process, but also has high strength. Although its strength is not as strong as steel, it is also quite durable.
5. Aesthetics
One of the main considerations for mechanical processing is the aesthetics of the finished product. Brass has a bright golden color, and its natural surface means that brass machined parts can be used without the need for additional surface treatment.
Brass Suitable For CNC Machining
1. Brass C360
Mechanists usually refer to this alloy as free machining brass, which is the most commonly used brass grade in machining and is known for its high machinability and tensile strength. Its high machinability is attributed to its approximately 3% lead content in its composition. Manufacturers use it to process brass custom parts, such as electrical equipment, connectors, or screws.
advantage
Easy to process;
Corrosion resistance;
Good tensile strength.
shortcoming
If used for medical purposes, lead content may cause problems,
Easily affected by acid.
2. Brass C230
Mechanists refer to this grade of brass as red brass or Nordic brass, which has moderate strength and good rust resistance. C230 is also popular due to its weather resistance and resistance to zinc removal. It is suitable for customized parts such as rotor rods, J-shaped bends, etc.
● advantage
Anti zinc removal;
Moderate tensile strength;
Corrosion resistance.
● shortcoming
May not be able to withstand corrosion in harsh environments.
3. Brass C220
Mechanists refer to this alloy as commercial bronze. Although it bears a similar name to bronze, its composition still belongs to brass alloy due to its high copper content. It has good machining performance, strength, and ductility.
advantage
Excellent corrosion resistance;
Good machining performance;
High ductility and strength.
shortcoming
Additional annealing treatment may be required after exposure to harsh environments.
