Metal aluminum sheet, which is costly and not tough enough, was not used for construction until the early 20th century = it was mainly used to decorate architectural details, and aluminum began to be used in roofs, waterproof boards, wallboards and spandrels. The first widespread use of aluminum in buildings was that parts of the tower structure and spire were made of aluminum, as well as components such as entrances, elevator doors, decorative panels and more than 6000 window arches.
As a material, aluminum also has an excellent strength to weight ratio, which means that the exterior wall system made of aluminum can be smaller than steel plates. Contemporary aluminum alloys can also support the weight of heavy glass spans to maximize the building's ability to use natural sunlight. The metal and its alloy components are light, matibay, corrosion-resistant and can be recycled indefinitely. According to statistics, roughly 75% of all aluminum products are still in use.
Aluminum is a white light metal with rich resources. The global output of aluminum is second only to steel.
Sa larangan ng application ng mga elektronikong produkto, dahil sa kanyang superior thermal at electrical kondaktibiti at mahusay na anti kalawang function sa pamamagitan ng aluminyo plate oksihenasyon teknolohiya, aluminyo haluang metal ay malawakang ginagamit sa circuit board, Thermal kondaktibo lupon, shell ng baterya, materyal ng lampara, tanso aluminyo composite board, circuit ilalim plate, kapangyarihan baterya shell, motherboard ng computer, tsasis shell, panloob na liner, panloob na partisyon, plug, socket na nga ba, wire, cable, atbp.
Compared with other materials, aluminum alloy is widely used in electronic products because of its advantages.
1. Ang density ng aluminyo ay maliit, alin ang 2.7g/cm, lamang ang 35% ng bakal. Ito ay isang mahusay na magaan na materyal. Ang ibabaw ng aluminyo ay maaaring natural na bumuo ng isang siksik na aluminyo oksido film, which can avoid further oxidation and has excellent antirust function.
2. Ang ibabaw ng aluminyo ay may mataas na kinang, maraming mga proseso ng pangkulay, madaling pangkulay at pagpapaganda.
3. Ang aluminyo ay may mahusay na ilaw at init na pagmumuni muni at mga katangian ng kondaksyon, which can enhance the effect of heating sterilization and low temperature treatment of food cans.
4. Ang mga mekanikal na katangian ng aluminyo ay maaaring manatiling hindi nagbabago sa mababang temperatura, particularly suitable for the packaging of frozen food.
5. The composite film made of aluminum foil is entirely airtight and light tight, which can effectively protect the internal food. Aluminum foil can also enhance the strength of aluminum-plastic composite film.
6. Maaaring i recycle ang basura, na hindi lamang maaaring makatipid ng pagkonsumo ng enerhiya, but also avoid public hazards caused by waste and meet the requirements of environmental protection.
