CNC Machining Brass: What are the Best Alloys

Are you looking for a material with good mechanical properties, strong corrosion resistance, good malleability, high conductivity, and even good acoustic characteristics? If so, you should consider brass because this remarkable metal has all those properties in one.Get more news about brass cnc machined parts wholesaler,you can vist our website!

Brass is an alloy of copper and zinc, the proportions of which can be varied to achieve different properties for the overall alloy. For that reason, brass is widely used in various industries and for applications ranging from musical and electrical to germicidal and antimicrobial.

This article will not only introduce you to the pros and cons of brass as a CNC machining material, but it will also help you to determine the best brass grades for use in your next project.
As we mentioned before, brass provides advantageous properties that make it an ideal option for a variety of applications. Why is that? When it comes to CNC machining, there are a few fundamental properties that make this material phenomenal.

The first one is the overall machinability. In simple terms, this property refers to how easy it is for the material to be machined. Brass is one of the easiest materials to machine. While many consider free machining steels the comparison baseline for machinability, brass alloys generally have better machinability.

The strength and hardness properties of brass are also useful for a wide range of applications. Although brass has good strength, it is relatively soft compared to other materials such as steel alloys and titanium and is generally weaker than them.

However, this contributes in part to its much better machinability over those materials. So for applications that do not require the very high strength and hardness of steels or titanium, brass can be a worthwhile materials selection.

Brass alloys exhibit the same favorable strength and hardness characteristics you would expect from various aluminum alloys. They also boast remarkable corrosion resistance, especially when alloyed with small amounts of aluminum.

While they do see use in some electronics — thanks to good overall conductivity — one of the significant considerations for brass over aluminum tends to be how visually appealing brass is without the need for additional coatings.

Best Brass Grades for CNC Machining
Brass, in its simplest form, is a combination of copper and zinc. However, alloying brass with combinations of other metals such as tin, aluminum, lead, and iron can produce brass alloys with unique characteristics.

Even in small proportions (<0.05%), the addition of those elements can also result in enhanced properties. For instance, a small amount of tin provides a brass alloy with exceptional resistance to seawater corrosion. Numerous brass alloys are used in CNC machining, with a wide variety of properties, and they are useful for distinct industries. The table below shows 10 of the most important brass alloys for you to consider for CNC machining projects:
