Leading aluminum machining manufacturer specializing in anodized metals and custom metal punch services.

In modern manufacturing, aluminium machining manufacturers play a vital role in producing high-precision components for industries like aerospace, automotive, and electronics. Combining advanced techniques such as custom metal punch fabrication with anodized metals ensures durability, corrosion resistance, and superior performance.

Anodizing Types

While there are some specialized anodizing types available for more niche purposes (i.e., phosphoric acid or titanium), there are three main types of anodizing that are chosen based on the application, material, and desired end result:

Type I

• Electrolyte: Chromic acid

• Layer thickness: 0.00002 to 0.0001 inches (0.5 to 2.5 microns)

• Properties: Good adhesion, non-conductive, electrically insulating, minimal dimensional impact, compatible with complex shapes

• Applications: Adhesive applications, paint and coating primers, aerospace components, weldments

Chromic acid anodizing forms the thinnest of the three oxide layers, but if properly sealed, it provides the same corrosion resistance as the other two. This coating absorbs less dye, typically resulting in a gray appearance, limiting its use in decorative applications.

However, chromic acid anodizing can be dyed black, making it ideal for optical component housings requiring both protection and light absorption. This characteristic makes chromic acid anodizing valuable in certain high-performance and specialized applications.

Processing	CNC Turning, CNC Milling, Laser Cutting, Bending, Spinning, Wire Cutting, Stamping, Electric Discharge Machining (EDM), Injection Molding
Materials	Aluminum: 2000 series, 6000 series, 7075, 5052, etc.
	Stainless steel: SUS303, SUS304, SS316, SS316L, 17-4PH, etc.
	Steel: 1214L/1215/1045/4140/SCM440/40CrMo, etc.
	Brass: 260, C360, H59, H60, H62, H63, H65, H68, H70, Bronze, Copper
	Titanium: Grade F1-F5
	Plastic: Acetal/POM/PA/Nylon/PC/PMMA/PVC/PU/Acrylic/ABS/PTFE/PEEK etc.
Surface Treatment	Anodized, Bead Blasted, Silk Screen, PVD Plating, Zinc/Nickel/Chrome/Titanium Plating, Brushing, Painting, Powder Coated, Passivation, Electrophoresis, Electro Polishing, Knurl, Laser/Etch/Engrave etc.
Tolerance	±0.002 ~ ±0.005mm
Surface Roughness	Min Ra 0.1~3.2

2.Complete produce equipment and test equipment. Independent Engineer team, to check drawings, provide quotation, write machining process, guide production.

3.Independent PMC department, to make production plan and manage delivery time.
4.Quick proofing, short delivery time, usually is 3-15 days

5 .The company has gathered a rich group of technologicallyadvanced modern talents, which has laid a stable foundationfor the long-term development of the company.

6.Complex and difficult surface and functional structureof the hand plate model, We can all mold quickly.xxx

Type II

• Electrolyte: Sulfuric acid

• Layer thickness: 0.0002 to 0.001 inches (5 to 25 microns)

• Properties: Highly porous, hard, wear- and corrosion-resistant, more affordable, compatible with a wider range of aluminum alloys

• Applications: Optical and electronic components, hydraulic valve bodies, electronic and computer housings

Sulfuric acid anodizing is the most widely used type of anodizing. It produces a harder coating than chromic acid anodizing and is more economical than the other two methods because it requires less energy, time, and chemicals. Furthermore, waste disposal from sulfuric acid anodizing is simpler and less expensive than that from chromic acid anodizing.

The porous layer of sulfuric acid anodizing effectively absorbs dyes before sealing, offering a wide variety of color shades. For frequently used applications, sealing after dyeing can minimize color fading, but it should be noted that this treatment does not completely prevent fading over time.The final look is clear and natural, making it an excellent base for dyeing, but it can also be left uncolored.
