Materials used in CNC machining and their characteristics (Aluminium ,copper and brass)


Precision high quality aluminum alloy parts CNC machining

Aluminium alloy 6061

6061 aluminum alloy is a high quality aluminum alloy produced by heat treatment pre-stretching process. Although its strength cannot compare with that of 2XXX series or 7XXX series, it has more characteristics of magnesium and silicon alloy.

Material advantages:

It has excellent machining performance, excellent welding characteristics and electroplating properties, good corrosion resistance, high toughness and no deformation after processing, easy polishing, easy coloring, excellent oxidation effect and other excellent characteristics.
7075 aluminum alloy

7075 aluminum alloy is a cold treated forging alloy, high strength, far better than mild steel.The 7075 is one of the most powerful alloys commercially available.

Material advantages:

General corrosion resistance, good mechanical properties and anodic reaction.Better deep drilling performance, enhanced wear resistance of tools, better thread rolling system.


Precision high quality copper parts CNC machining

Pure copper (also known as red copper) is a metal with excellent electrical conductivity and toughness, and has a rosy red surface.But it is not pure copper, it contains 99.9% copper, and some other elements are added to improve the surface and performance.

Material advantages:

It has good electrical conductivity, thermal conductivity, ductility and corrosion resistance.

Copper conductivity and thermal conductivity is second only to silver, widely used in making conductive and thermal equipment.Copper has good corrosion resistance in the atmosphere, seawater and some non-oxidizing acids (hydrochloric acid, dilute sulfuric acid), alkali, salt solution and a variety of organic acids (acetic acid, citric acid). It is used in chemical industry.

It has good weldability and can be processed into various semi-finished products and finished products by cold and thermoplastic processing.In the 1970s, the output of red copper exceeded that of all other copper alloys.

Precision high quality brass parts CNC machining

Brass is an alloy of copper and zinc.Brass consisting of copper and zinc

Material advantages:

It has high strength, high hardness and strong chemical corrosion resistance.The mechanical properties of cutting are also better.

Brass has strong wear resistance.Brass is also called special brass, it is high strength, hardness, strong chemical corrosion resistance.The mechanical properties of cutting are also higher.Made of brass seamless copper pipe, soft, strong wear resistance.
