What active elements are affected by spot corrosion of LED aluminum profiles

The zinc solid dissolved in the LED aluminum profiles accelerates grain corrosion in a "dissolution-redeposition" manner. The zinc or iron deposited on the alloy(LED aluminum profiles) surface as well as cathodic particles such as high-potential desolvation products FeSiAl and free silicon can act a......

Analysis on the formation mechanism of spot corrosion of LED aluminum profiles

6063 is an Al-Mg-Si alloy, and Mg2Si is the only aging strengthening phase. In order to improve the strength of LED aluminum profile alloys, the Si element content is often excessive during production, and free Si and FeSiAl phase particles are formed from the excess Si.

Analysis of the causes of spot corrosion of LED aluminum profiles

The main factors that affect the spot corrosion of LED aluminum profiles include the alkali cleaning temperature and alkali cleaning time during the pretreatment process, the Zn, Fe, and Si element contents in the alloy composition and the extrusion state of the alloy.

Analysis of the nature of spot corrosion of LED aluminum profiles

It can be seen from the composition of the 6063 LED aluminum profile used that in order to ensure that the Mg element fully forms the strengthening phase Mg2Si, an appropriate amount of Si element is generally artificially excessive when formulating the alloy composition.

Will LED aluminum profiles corrode

6063 LED aluminum profiles have good corrosion resistance and decorative properties after anodization.

What is the difference between LED mosquito killer lamp and ordinary mosquito killer lamp

terms of lighting principles, energy-saving effects, lifespan, price, luminous quality, safety, etc. Since they are too professional, I won’t explain too much here. Let’s briefly talk about the LED light sources used in mosquito killer lamps.
