Benefits of CNC Aluminum Parts
High strength but light weight
Aluminum's density is only about one-third that of steel, that’s why aluminum products lighter and save machining cost, Also after alloying and heat treating, its strength can be greatly increased to meet the mechanical strength requirements of a wide range of applications. This high strength-to-weight ratio is particularly important in the aerospace and automotive industries.
Easy Machining
Aluminum is easier to work with than other metals, and it can be easily stamping, folding, and drilling to create a variety of precise and complex parts in a variety of shapes. Aluminum CNC machining uses less energy and produces parts faster than steel machining.
Corrosion Resistance, Low Temperatures Resistance
Aluminum forms an oxide layer when exposed to air, protecting the metal from corrosion and chemical attack. Aluminum has different corrosion resistance depending on the grade of the material, and the most commonly used in aluminum CNC machining is 6061, which is usually used for automotive parts, sporting goods, some aircraft parts, etc.
Aluminum material is resistant to low temperatures, compared with other metals, aluminum is easier to process at low temperatures.
Variety Of Surface Treatments
Aluminum CNC parts with a variety of surface finishing, such as Anodized, ,Laser carving,plating, painting, etc. Aluminum alloy surface treatment have their unique advantages, and different surface treatment should be selected according to specific usage scenarios. Consider factors such as wear resistance, corrosion resistance, and decorative properties when selecting, in order to ultimately achieve the best treatment effect.

Why choose Aluminum for CNC Machining?
CNC aluminum parts are usually less expensive
because they can be machined within a short period compared to other metals like steel. They also do not need extra finishes. Small quantities of zinc, magnesium, copper and other materials are added for strength because the pure aluminum metal is usually soft. When exposed to the atmosphere, a thin protective layer is formed which makes it resistant to corrosion and reduces the chances of it catching rust on the surface. It is resistant to chemicals, easy machining capabilities, and also has a lot of strength compared to its weight.
Aluminum weighs about a third as much as steel.
It also conducts heat and electricity easily which makes it the perfect material for steel sinks. Aluminum reflects heat and light, is malleable and non-magnetic. Some companies specialize in the production of custom CNC aluminum parts. This is mostly because they are economical and lightweight. Aluminum CNC parts are usually less expensive because they can be machined within a short period compared to other materials like brass and steel. It does not also require new finishes.

CNC Machining Surface Finishes
CNC machining surface treatment refers to a series of physical or chemical treatment processes on the workpiece surface after the part is cut by a CNC machine tool (Computer Numerical Control). The main purpose of these treatments is to improve the appearance, function or durability of the parts to meet design requirements and practical application needs.
As Machined
The surface of the parts formed after processing will have clear processing lines, and usually there will be surface treatments such as deburring and sharp edge removal.
Anodizing
It is the process of forming an oxide film on the metal surface by electrolysis.
Powder coating
The powder coating is sprayed onto the aluminum surface by electrostatic adsorption and cured at high temperature to form a coating.
Black Oxidation
Refers to the process of forming a dense, uniform, microporous black oxide film on the surface of aluminum through electrolysis.
Plating
The process of depositing a layer of metal or alloy on the surface of aluminum by electrolysis to improve conductivity, wear resistance, decorative properties or corrosion resistance.
Sandblasting
It is a pretreatment performed before metal surface preparation, metal priming, painting surfaces or bonding.
Heat Treatment
An important metal processing technology that changes the internal structure of metal parts by heating and cooling, thereby significantly improving their material properties.
Polishing
Chemical or electrolytic polishing to obtain mirror effect, often used for high-gloss parts.
Brushed Finish
A surface treatment method that uses a flat-pressed abrasive belt and a non-woven roller brush to form lines on the workpiece surface to achieve a decorative effect.
Electrophoresis
The electric field is used to deposit charged paint particles on the aluminum surface to form a uniform coating.
Passivation treatment
A surface treatment technology designed to enhance the corrosion resistance of stainless steel and other specific metal materials.
Milling/Grinding
Specific textures or geometric structures are formed by CNC machining or belt sanding.
