무엇인가 1, 2, 3, 4, 5, 6, 7, 8 series aluminum alloys？

What does the number number of the aluminum alloy represent? 일반적인 알루미늄 합금 모델은 무엇입니까? 지난 기사에서, 알루미늄의 의미와 공통 제품 모델을 공유했습니다. 1000 시리즈와 2000 시리즈 알루미늄 금속 번호. 오늘, we continue to share the digital meanings and common aluminum alloy models of 3, 4, 그리고 5 series aluminum alloy products.

Ⅰ: 3 series aluminum products

그만큼 3000 series alloy is mainly composed of Mn (content in the range of 1.0-1.5) + Al metal. 그중, the representative alloy models are 3003 3004 3A21. 3 series aluminum alloys are commonly used in household appliances, body frames, 등. It has the characteristics of good corrosion resistance and rust resistance. The price is higher than the first series.

Ⅱ: 4 시리즈 알루미늄 합금.

그만큼 4000 series aluminum alloy is mainly Al+Si (content is 4.5-6.0%) metal, and the silicon content is relatively high. 그중, the representative models of 4 series aluminum metal are 4A01, 4006, 4007, 4015, 4047. 4 series aluminum products are mostly used in architectural scenes and belong to building materials. It is also commonly used in mechanical parts, welding materials, 재활용 가능; it has the characteristics of low melting point and good corrosion resistance.

Ⅲ: 5 series aluminum products.

5000 series is a relatively common type of aluminum alloy. It uses Mg (with magnesium content between 3-5%) as the main alloy and has the characteristics of low density and super tensile strength. Common 5-series alloy models represent the 5052.5005.5083.5A05 series.
The elongation of 5-series alloys is very good, and they are mostly used in aerospace materials, such as aircraft chassis.
In China, 그만큼 5000 series aluminum alloy is one of the more mature aluminum alloy product series.
