What are the methods for surface treatment of aluminum bars?（二）

Wire drawing treatment:

Repeatedly use sandpaper to scrape the surface of the aluminum rod, creating a linear texture on its surface.

The brushed aluminum rod has a unique metallic texture, giving people a refined and high-end visual experience.

High gloss cutting:

Using a high-speed rotary carving machine to cut aluminum bars, creating localized bright areas on their surface.

The brightness of the cutting highlight is affected by the speed of the milling drill bit, and the faster the drill bit speed, the brighter the cutting highlight.

Electrophoretic coating, powder coating:

Electrophoretic coating can make the surface of aluminum rods glossy and soft, and can resist the erosion of cement and mortar acid rain.

The characteristics of powder electrostatic spraying profiles are excellent corrosion resistance, acid, alkali, and salt spray resistance, which is much better than oxidation coloring profiles.

In summary, there are various methods for surface treatment of aluminum rods, each with its unique advantages and applicable scope. In practical applications, appropriate surface treatment methods should be selected based on factors such as the specific purpose, usage environment, and cost requirements of the aluminum rod.
