Experience Sharing! What should be paid attention to for aluminum alloy prototype oxidation

oxidation is a process that is often encountered during the prototype processing of aluminum alloy. Natural oxidation will cause the surface of aluminum alloy prototype to be difficult to see, so artificial oxidation is needed. When the aluminum alloy is oxidized, there are many precautions. Let's introduce them to you.

1. Before the oxidation of the aluminum alloy prototype, sand blasting is usually performed to make the prototype surface more beautiful, the impact of high-speed sand flow is used to reduce the roughness of the surface and form a grain, so that the oxidized aluminum alloy prototype is very exquisite. However, if the customer requires true color oxidation, no sand blasting is needed. The prototype of the aluminum alloy box as shown in the following figure is the true color oxidation.

2. Sandblasting should be uniform: the sandblasting pressure should be consistent, the nozzle should move smoothly, the injection angle should be consistent, and the gun should not be fired on the part. The nozzle is consistent with the workpiece distance.

3. Under normal circumstances, stainless steel and copper cannot be oxidized, only aluminum alloy can be oxidized, but different aluminum alloy materials have different oxidation effects. The oxidation effect of aluminum alloy 7075 is not good because its composition contains copper, aluminum alloy, which usually starts with 5 and 6, can be oxidized, while aluminum alloy 6061-The oxidation effect of T6 is better.

Therefore, when the aluminum alloy prototype is oxidized, it is necessary to pay attention to the customer's needs, the uniformity of sandblasting and the oxidized materials.
