Common Surface Finishes for china copper cnc machining Parts


1. Copper bright cleaning: The purpose of this surface treatment is to
thoroughly clean the stains, impurities, spots, oil stains and other dirt on
the copper surface, and restore the bright color of the copper itself.

2. Copper passivation: Since copper is an active metal, it is particularly easy
to oxidize and grow spots, and even appear patina in humid or special
environments. Copper passivation can effectively protect the surface of copper
parts.

3. Anodic oxidation: use copper as an anode, and use electrolysis to form an
oxide film on the surface. The oxide film changes the surface state and
performance, such as surface coloring, improves corrosion resistance, enhances
wear resistance and hardness, and protects the surface of copper parts.

4. Electroplating: The purpose of electroplating is to plate a metal coating on
the copper substrate to change the surface properties or dimensions of the
copper substrate. Electroplating can enhance the corrosion resistance of
copper, increase hardness, prevent wear, improve electrical conductivity,
smoothness, heat resistance and beautiful surface.

5. Copper chemical polishing: Soak the copper parts directly in the copper
chemical polishing solution, so that it can quickly reach a bright and
beautiful color, and at the same time quickly remove surface oxides. The
surface size will change accordingly, but it can be controlled artificially .
Copper parts after chemical polishing need to be passivated as soon as possible
to prevent them from being oxidized and discolored again.

CNC Machining Copper Properties and Advantages

Copper is a reddish, highly malleable metal. In CNC metal processing, pure
copper is difficult to machine due to its high plasticity and toughness, while
most copper alloys with other elements such as aluminum and zinc have improved
or even better machinability. It has become a popular material for cnc
machining parts. Copper has unique advantages such as excellent corrosion
resistance, ductility, thermal and electrical conductivity that make it an
excellent material for CNC machining and a variety of uses. CNC copper
machining produces precision parts to ensure high consistency and precise
dimension.

Types of Copper Alloys in copper machining

There are two types of copper alloys widely used for CNC machined parts. These
materials have good electrical and thermal conductivity. CNC copper parts are
widely used in automobiles, electronic products, medical products, home
appliances, security products, aerospace, power industry and many other
industries.

Copper C101: C101 is named for its purple-red color. Red copper is industrial
pure copper with a melting point of 1083°C, no allotropic transformation, and
a relative density of 8.9, which is five times that of magnesium. About 15%
heavier than ordinary steel. It has a rose red color and is purple after an
oxide film is formed on the surface, so it is generally called red copper. It
is copper that contains some oxygen, so it is also called oxygen-containing
copper. C101 has good electrical conductivity, thermal conductivity, corrosion
resistance and processability, and can be welded and brazed. Contains less
impurities that reduce electrical conductivity and thermal conductivity, and
trace oxygen has little effect on electrical conductivity, thermal conductivity
and processing properties, but it is easy to cause "hydrogen disease", so it is
not suitable for processing (annealing, welding, etc.) and use.

Copper C101 is mainly used as conductive, thermally conductive and corrosion-
resistant components, such as wires and cables, conductive screws, shells and
various conduits and aviation industry

C110 Copper: Copper C110 is a certified very high purity oxygen-free copper
grade suitable for electronic type applications. The material is made of pure
cathode copper and cast in a protective gas atmosphere. It has a minimum copper
content of 99.99% and a minimum electrical conductivity of 101.5% IACS.

It combines the highest thermal and electrical conductivity values, excellent
formability, adherent oxide film and excellent joining/soldering properties and
can also be used in the electrical and high vacuum industries.
