| As-machined (Non-surface treatment ) | Surface roughness 3.2 μm (126 μin) | All materials | Nature color | Stain |
| Sand Blasting | Sand blasting with powerfully propelling high pressure, a stream of blast media against a surface to remove unwanted coating layers and surface impurities | Aluminum, Steel, Stainless Steel, Brass, Copper | Natrue color | Matte |
| Anodizing | Keeping parts in the long term, anodizing process resists corrosion and wear. It’s also an ideal surface treatment for painting and priming, and it looks great | Aluminum | Clear, black, grey, red, blue, gold | Smooth, matte finish |
| Electroplating | Electroplated coating preserves the surface rusts and decay by applying electric currents to reduce metal cations. | Aluminum, steel, stainless steel | Gold, silver, nickel, copper, brass | Smooth, glossy finish |
| Polishing | Ranging from Ra 0.8~Ra0.1, polishing processes use an abrasive material to rub the part’s surface to make them shine more less shiny, depending on your requirements. | All materials | Natrue color | Smooth, glossy finish |
| Powder Coating | Using corona discharge, we make the powder coating adsorbed to the part, creating a more wear-resistant layer with a typical thickness ranging from 50 μm up to 150 μm. | All metal materials | Customized color | Glossy |
| Brushing | Brushing is a surface treatment process in which abrasive belts are used to draw traces on the surface of a material, usually for aesthetic purposes. | ABS, Aluminum, Brass, Stainless Steel, Steel | Natrue color | Satin |
| Painting | Painting involves spraying a layer of paint onto the surface of the part. Colors can be matched to a Pantone color number of the customer’s choosing, while finishes range from matte to gloss to metallic. | Aluminum, Stainless Steel, Steel | Customized color | Gloss, semi-gloss, flat, metallic, textured |
| Black Oxide | Black oxide is a conversion coating similar to Alodine that is used for steel and stainless steel. It is used mainly for appearance and for mild corrosion resistance. | Steel, Stainless Steel | Black | Smooth, matte |
| Alodine | Chromate conversion coating, known as Alodine, is a chemical coating that passivates and protects aluminum from corrosion. It is also used as a base layer before priming and painting parts. | Aluminum | Clear, Gold | Same as before |
| Silk Print | Part marking is a cost-effective way to add logos or custom lettering to your designs and is often used for custom part tagging during full-scale production. | All materials | Customized color | Non |
Our customized aluminum parts offer a range of benefits to various industries, including aerospace, automotive, and construction. These custom machined metal parts are designed and manufactured based on specific client requirements, making them a perfect fit for their intended applications. Here are the reasons why you chose our CNC billet aluminum machined parts.
Highly resistant to corrosion. Aluminum is naturally resistant to corrosion, and our aluminium custom parts are treated with special coatings to prevent rust, oxidation, and other forms of damage. This makes them ideal for use in harsh environments or structures where durability is required.
Light Weight. Our custom billet parts are also beneficial due to their lightweight nature. Aluminum is significantly lighter than other metals, making it an ideal choice for applications such as aerospace, where weight is critical. This makes our aluminium custom parts an excellent choice for clients looking to reduce material weight and enhance the performance of their products.

HSJ is a trustworthy metal cnc parts supplier, and with our expertise and understanding of different coatings, we can recommend the most suitable options that align with the client's specific needs. Whether it's a particular color, texture, or resistance to weather or corrosion, we can provide the ideal finish that suits your aluminium custom parts.
Typically, aluminum is classified and categorized based on its function and falls into eight series:
One series (1050, 1070, 1080, 1085, 1100)
These aluminum alloys are characterized by a purity of 99.00% or more. They offer good formability and have a good surface finish, with higher corrosion resistance. However, their strength is low, and the higher the purity, the lower the strength. They are commonly used in mobile phones, extrusion processes (not bending), and decorative or interior parts. Specifically, 1050 and 1100 can be chemically sanded to achieve a glossy, matte, or normal effect, while 1080 and 1085 can be mirror-finished with a bright word or matte effect, with no obvious material pattern.
Two series (2024, 2A16, 2A02)
This category of aluminum alloys has a higher hardness but poor corrosion resistance, with the highest copper content (3% to 5%). The 2000 series aluminum alloys include 2024, 2A16, and 2A02. They are used in aerospace areas and construction for rods.
Three series (3003, 3105, 3A21)
These aluminum alloys are mainly made of manganese (1.0 to 1.5) and provide good rust resistance. The 3000 series aluminum alloys include 3003, 3105, and 3A21. They are commonly used in tanks and jars for liquid products, construction, tools, various lamp parts, pressure vessels, and pipes for thin plate processing. They offer good formability, solubility, and corrosion resistance.
Four series (4A01)
This category of aluminum alloys has a silicon content of 4.5% to 6.0%, providing higher strength. The 4000 series aluminum bar is represented by 4A01 and has good soup flow, less solidification shrinkage, and is used for building materials, mechanical parts, forging materials, welding materials. They have a low melting point and good corrosion resistance, with heat and wear resistance characteristics.
Five series (5052, 5005, 5083, 5A05)
These aluminum alloys are used in the alloy aluminum sheet series and contain magnesium as the main element (3% to 5%). The 5000 series aluminum alloys include 5052, 5005, 5083, and 5A05. They are called aluminum-magnesium alloys with low density, high tensile strength, and high elongation. They are suitable for sandblasting processes, have medium strength, good corrosion resistance, solubility, and formability, and have high fatigue strength and good resistance to seawater. They are mainly used in casting molding methods but not suitable for extrusion molding.
Six series (6061, 6063)
These aluminum alloys belong to the 6000 series and contain mainly magnesium and silicon, combining the advantages of the 4000 and 5000 series. They are easy to work with, easy to coat, and have good machinability. The 6000 series aluminum alloys include 6061 and 6063. They are more commonly used in mobile phones, with 6061 being stronger than 6063. They are used for casting and forming and can be cast in more complex structures, and can be used for parts with snaps, such as battery covers.
Seven series (7075)
The 7000 series aluminum alloy represents 7075, which also belongs to the aerospace series and is an aluminum-magnesium-zinc-copper alloy. Currently, it is mainly imported, and the production process in China.
The cost of CNC aluminum parts customization depends on the complexity and size of the part and the type of Aluminum. These variables will affect the type of machine that is required, the time it takes to produce the part and the cost of the raw material.
Aluminum parts fabrication is the process of creating custom-made components using aluminum as the base material. This process involves several steps such as designing, cutting, bending, welding, and assembly to produce high-quality aluminum parts that meet specific client requirements.
First, start by doing thorough research on potential factories, including their reputation within the industry and any customer reviews. Additionally, make sure to ask for samples of their work to ensure their product quality meets your standards. You should also inquire about their manufacturing process and their experience in producing customized aluminum parts for your specific application. It is also important to verify their certifications and compliance with industry standards.
