작은 비중으로, 쉬운 가공 및 높은 기계적 강도, 알루미늄 시트는 문에서 수년 동안 널리 사용되었습니다., 창문, 건물의 외벽 및 기타 제품. 알루미늄은 은빛 광택을 지닌 비교적 활동적인 경금속입니다., 내식성에는 다음과 같은 두 가지 특성이 있습니다..

순도가 높을수록, 더 나은 내식성, mainly because pure aluminum acts with oxygen in the air to produce a very thin layer of dense natural oxide film on the surface of aluminum, which is faster and much thicker than other metal oxide films generated, thus preventing further corrosion by harmful gases and moisture in the air and playing a protective role.

The mechanical strength of aluminum sheet is high, but the corrosion resistance is low. Although the corrosion resistance of pure aluminum is good, but the mechanical strength is poor, which to a certain extent restricts the application of aluminum, for this reason, people add the right amount of magnesium, 구리, zinc and other metals in aluminum to make various types of aluminum alloys, so that the mechanical strength of aluminum is greatly improved, and the application range is greatly expanded, but the corrosion resistance is worse than pure aluminum, so there is a possibility of corrosion due to oxidation. This requires powder coating to protect the aluminum alloy profile.

In addition to high corrosion resistance, the 알루미늄 시트 분말 코팅 also has many advantages, such as diversified colors and good surface texture, which can be echoed with various colors of building exterior paint to adapt to different building styles.
