What is CNC Machining Brass?

Brass is an alloy composed of copper and zinc, name for its yellow color. The content for cooper is 56% to 68% and melting point of 934 to 967°. Brass has good mechanical properties and wear resistance, and can be used to manufacture precision instruments, marine parts, and shells of guns. Generally, they are widely used for auto parts, medical parts, and electrical parts.Due to the content of lead, making brass become one of the most favorable materials for CNC machining.



What are the benefits of CNC Machining Brass?

Due to its low friction, good machinability and excellent electrical conductivity, brass material is widely used in electronics, medical industries which requires the parts with very precision dimension.CNC machining brass could meet such high requirements. Compared with other metal materials, brass has the following advantages:

1) Brass has high strength, good plasticity, can withstand cold and hot pressure well, and has good welding and corrosion resistance properties.

2) Good cutting performance, easy to weld, and stable to general corrosion.

3) Cheap material cost but withstand pressure in hot temperature,

4) Good mechanical properties

5) Good toughness, anti-friction properties, high corrosion resistance in the atmosphere and sea water.

Justin, CEO of a lighting company

I inspected the top two pieces of all five boxes. Everything is beautiful! BEAUTIFUL! You remove so much stress from my shoulders. I know that when we pay you to manufacture a product, it will be made perfectly. The glass bead blasting and anodizing is always beautiful. I am so very happy! You make it easier for us to run our business. There is no trouble! With most factories, I have a moment of fear before I open their boxes. Will the components be made correctly? Do they care about quality? It is often a war. And Dennis has to fight the war, treating most factories like small children! But, not your company. You’re company is world-class. You make beautiful components!Thank you very much for your hard work. We will work together for many lifetimes!

David, General manager for a family owned business

I’ve been working with Chinese manufacturers since 2004 and had some really unfortunate partnerships until 2012 when we partnered with Worthy Hardware. At first,we only gave them small orders to test and make the start. However,their response speed was very fast ,and their engineers help us improved our designs more simple, this helped us reduce a lot of cost.Our cooperate is more and more stable! We trust Worthy Hardware always ,very responsible. Your guys are great! .Worthy Hardware is by far my favorite, because of the way they handle business and the quality of what they make.If you are from USA and would like to know more about Worthy Hardware,i would be very happy to be as an endorsement.


CNC Machining Brass FAQ

1.What is the difference between brass and copper in CNC machining?

Generally speaking, the machining performance of brass is better than copper (copper is easy to stick to the knife); However ,copper has less resistance to deformation and is easier to form.

2.Do you have the ability to machine other kinds of brass material by CNC machining?

From the above article we just listed the frequently used brass material for CNC machining,if you have other brand brass material,just send them to us for quote and produce,all the material we supplied is real and qualified. We will supply the material certificate, SGS report and RoHS report.

3.How to machine the brass with very shiny surface?

Normally the cutting speed for brass is 280 turns/minute,so if you want to make more shiny surface,increase the speed of rotation, while cooling with coolant.
