Custom CNC Machining Brass Parts & Copper Parts

HKAA-professional custom CNC machining parts manufacturer with quality CNC machining centers

Custom CNC machining brass parts

Custom CNC machining brass parts is a common process in manufacturing. Brass is a popular material due to its excellent machinability, corrosion resistance, and aesthetic appeal. Generally speaking, most CNC copper parts have good machinability, ductility and impact strength. They also have high thermal conductivity, electrical conductivity, corrosion resistance and wear resistance. Therefore, copper is of great value in a variety of industrial applications. CNC copper machining is a precision machining technology used in various industries to manufacture copper parts. However,

some skills are also required in the processing of copper parts.

CNC makes copper processing easier

Computer Numerical Control (CNC) is one of the most popular manufacturing technologies for machining applications, thanks to the high speed, precision, precision and compatibility of CNC machine tools with a variety of materials. In addition, the use of CNC machining to process various materials into required parts has become very common, and copper is no exception. Previously, processing copper was very cumbersome due to its high elasticity and toughness. However, CNC machining technology has made the processing of copper parts much more manageable, all thanks to the

automated process in machining, known as CNC.

Product advantages

Copper is one of the major categories of commercial metals, and you'll find different grades of copper available for copper parts processing. In addition, they have different properties suitable for specific machining projects.

Pure copper

Pure copper is usually soft and ductile, and diluted grades of pure copper contain small amounts of various alloying elements. This therefore helps in changing one or more of the basic properties of pure copper into the desired properties. Likewise, adding other alloying elements to pure copper will also increase its toughness. Commercially pure copper contains approximately 0.7% impurities in its composition. Their UNS numbers are C10100 to C13000, depending on the added elements and impurity content. Pure copper is best used in making electrical equipment, including wires and motors. Additionally, this copper is suitable for use in industrial machinery such as heat exchangers.

Electrolytic copper

Electrolytic copper is derived from cathode copper, which refers to copper refined by electrolysis. Generally speaking, the process involves injecting a copper compound into a solution and then applying enough electrical energy to help purify the copper material. Therefore, most electrolytic copper has lower impurity levels than other grades of copper.
C11000, the most common of all electrolytic coppers, typically contains less than 50 parts per million of metallic impurities, including sulfur. In addition, they are highly conductive, up to 100% IACS (International Annealed Copper Standard). Its excellent ductility makes it suitable for electrical applications including windings, cables, wires and busbars.

Oxygen-free copper

Compared to other copper species, oxygen-free copper contains almost no oxygen. In most cases, oxygen-free copper grades include many highly conductive electrical copper components. However, C10100 and C10200 are the most common. C10100, known as Oxygen-Free Electronic Copper (OFE), is a pure copper containing approximately 0.0005% oxygen. Additionally, it is also the most expensive of these copper grades. In addition, C10200 is also called oxygen-free copper (OF), with an oxygen content of about 0.001%, and its electrical conductivity is also very high. These oxygen-free copper materials are manufactured by induction melting using high-quality cathode copper. During the production process, the copper cathode is melted under non-oxidizing conditions covered by a graphite bath. Oxygen-free copper is highly conductive and is best suited for use in high-vacuum electronics, including launch tubes and glass-to-metal seals.

Free cutting copper

This copper material is composed of various alloying elements. Major elements include nickel, tin, phosphorus and zinc. The presence of these elements helps improve the machinability of this copper material.
