材質(zhì)可以理解為材料質(zhì)量，但是在鋁合金里面材質(zhì)主要指的是合金含量，也就是我們常說(shuō)的5052鋁板，5083鋁板等均是指的材質(zhì)，而在材質(zhì)證明中的材質(zhì)還包括力學(xué)性能這一個(gè)因素，綜合而言我們可以講材質(zhì)理解為兩個(gè)部分，個(gè)部分是化學(xué)成分也就是我們常說(shuō)的合金含量另外一種及時(shí)力學(xué)性能，包括延伸率和抗拉強度兩個(gè)指標。
Material quality can be understood as material quality, but in aluminum alloy, material mainly refers to the alloy content, that is, 5052 aluminum plate and 5083 aluminum plate, which we often refer to, and the material in the material certificate also includes the factor of mechanical properties. Generally speaking, we can understand material as two parts, The first part is the chemical composition, that is, the alloy content, another kind of timely mechanical properties, including elongation and tensile strength.
其實(shí)在常規術(shù)語(yǔ)中我們通常默認材質(zhì)僅僅指的是合金含量，也就是如果要求材質(zhì)是某一種合號那么化學(xué)成分必須能夠滿(mǎn)足該牌號的標準，而力學(xué)性能通常體現在了狀態(tài)方面，比如在標準的鋁板訂單中會(huì )出現5052-H32，其中5052指的是材質(zhì)，而H32指的是力學(xué)性能。
In fact, in conventional terms, we usually default that the material only refers to the alloy content, that is, if the material is required to be an alloy brand, the chemical composition must meet the standard of the brand, and the mechanical properties are usually reflected in the state. For example, 5052-H32 will appear in the standard aluminum plate order, in which 5052 refers to the material and H32 refers to the mechanical properties.

如何來(lái)確認材質(zhì)是否合格：這一點(diǎn)需要的儀器設備才能夠進(jìn)行確認，實(shí)際上很多用戶(hù)都不會(huì )檢驗而銷(xiāo)售商也不敢用其它材質(zhì)替代，所以材質(zhì)往往還是依靠誠信來(lái)保證的，當然如果對于要求較為嚴格或者數量較大的訂單也可以委托第三方檢測結構進(jìn)行材質(zhì)檢測。
How to confirm whether the material is qualified: this can only be confirmed by professional instruments and equipment. In fact, many users will not inspect it, and sellers dare not replace it with other materials, so the material is often guaranteed by integrity, Of course, for orders with strict requirements or large quantities, a third-party testing structure can also be entrusted for material testing.
鋁的熔點(diǎn)低，鑄造性能好。鋁的力學(xué)性能與其純度有很大關(guān)系，工業(yè)鋁板強度低，但鋁和某些合金元素組成的鋁合金，不僅在某種程度上仍保持著(zhù)鋁固有的特點(diǎn)，同時(shí)又顯著(zhù)提高了它的硬度和強度。某些鋁合金用作結構材料時(shí)，其強度可超過(guò)一般結構鋼；別一些鋁合金用作模具材料時(shí)，其使用壽命可超過(guò)一般模具鋼。鋁和多種鋁合金均有的延展性，可以進(jìn)行各種塑性加工。
Aluminum has low melting point and good casting performance. The mechanical properties of aluminum are closely related to its purity. The strength of industrial aluminum plate is low, but the aluminum alloy composed of aluminum and some alloy elements not only maintains the inherent characteristics of aluminum to some extent, but also significantly improves its hardness and strength. When some aluminum alloys are used as structural materials, their strength can exceed that of general structural steel; When some aluminum alloys are used as die materials, their service life can exceed that of general die steel. Aluminum and a variety of aluminum alloys have excellent ductility and can be processed in a variety of plasticity.
任何一種鋁合金的機械加工性能都優(yōu)于鋼和純鋁，但各種變形鋁合金與鑄造合金的機械加工性能能有很大的差別。鋁及鋁合金是屬于容易成形的金屬材料之一，但是鋁合金所容許的形變量受其化學(xué)成份、品級及其熱處理的影響。由于鋁合金的機械強度和加工硬化率均較低，因此與其他金屬的成形性能有所不同。
The machinability of any kind of aluminum alloy is better than that of steel and pure aluminum, but the machinability of various deformed aluminum alloys and cast alloys can be very different. Aluminum and aluminum alloy are one of the most easily formed metal materials, but the allowable deformation of aluminum alloy is affected by its chemical composition, grade and heat treatment. Because the mechanical strength and work hardening rate of aluminum alloy are low, its formability is different from that of other metals.
機械制造業(yè)廣泛用鋁板制造車(chē)輪、滑輪、離心機、通風(fēng)機、起重機及泵的零部件、活塞和發(fā)動(dòng)機氣缸，以及鋁板沖壓件等。
The machinery manufacturing industry widely uses aluminum plates to manufacture wheels, pulleys, centrifuges, ventilators, crane and pump parts, pistons and engine cylinders, as well as aluminum plate stamping parts.
這是由于鋁及鋁合金的特點(diǎn)不僅密度小，而且能具有所要求的強度和硬度，從而能降低機械運轉中的能量消耗，或者在使用相同能量的條件下大大地提高運轉速度，也相對一延長(cháng)了機件的使用壽命。同時(shí)，整個(gè)機器的重量減輕、尺寸減小后，更能適應生產(chǎn)、運輸、安裝和操作。
This is because the characteristics of aluminum and aluminum alloy not only have low density, but also have the required strength and hardness, which can reduce the energy consumption in mechanical operation, or greatly improve the operation speed under the condition of using the same energy, but also relatively prolong the service life of the parts. At the same time, after the weight and size of the whole machine are reduced, it can be more suitable for production, transportation, installation and operation.
歸納起來(lái)，工業(yè)鋁板的用途主要為以下幾個(gè)行業(yè)：建筑工業(yè)、容器包裝、交通運輸、電力工業(yè)、食品工業(yè)、機械設備、耐用消費品行業(yè)以用其他類(lèi)等。近20年來(lái)，建筑、汽車(chē)、包裝用鋁已成為工業(yè)發(fā)達國家的鋁材三大用途。
The following industries are mainly used for industrial and transportation equipment, such as aluminum and other durable goods. In the past 20 years, aluminum for construction, automobile and packaging has become the three major uses of aluminum in industrial developed countries.
