Aluminum alloy is the general term for aluminum-based alloys. The main alloying elements are copper, silicon, magnesium, zinc, and manganese, and the secondary alloying elements are nickel, iron, titanium, chromium, lithium and so on.
Some people think that aluminum alloy is a metal composite sheet, but it is not. So what is the difference between metal composite sheet and aluminum alloy?
Let me talk about the conceptual difference between the two first. The metal composite sheet is a single layer of metal and then covered with a single layer of metal. According to its classification, it can be divided into titanium steel composite sheet, stainless steel composite sheet, steel copper composite sheet, and steel composite sheet. and many more.
Aluminum alloy is a metal material synthesized by dissolving aluminum and adding other metals. It is an organically combined state. According to its classification, it can be divided into aluminum-manganese alloy, aluminum-magnesium alloy, aluminum-zinc alloy, aluminum-copper alloy, etc. Wait. #Stainless steel#
Furthermore, the processing technology and usage scenarios of the two are different. The processing technology of metal composite sheet includes rolling composite, explosive composite, comprehensive composite, etc., which are mostly used in anti-corrosion engineering, container manufacturing, construction, petrochemical, medical, automotive and other industries.
The processing technology of aluminum alloy includes sandblasting, polishing, wire drawing, high-gloss cutting, anodizing, etc. Because of its light weight, it is mostly used in aerospace, machinery manufacturing, marine and automotive industries, and it is also commonly used in construction engineering, doors and windows. application.
Aluminum alloy has low density, but relatively high strength, which is close to or exceeds that of high-quality steel. It has good plasticity and can be processed into various profiles. It has excellent electrical conductivity, thermal conductivity and corrosion resistance. It is widely used in industry and its usage is second only to steel. .
Aluminum alloys are divided into two categories: cast aluminum alloys, which are used in the as-cast state; deformed aluminum alloys, which can withstand pressure processing and have higher mechanical properties than the as-cast state. It can be processed into various shapes and specifications of aluminum alloy materials. Mainly used in the manufacture of aviation equipment, daily necessities, doors and windows for construction, etc.
