盡管成品鋁合金外殼價格普遍較貴，但購買數量不少。根據市場上的實際情況，成品鋁合金外殼的質量不(bu)同，價格也隨之(zhi)波動。因此，在選購的時候，我(wo)們應(ying)該根據自己的實際情況來選擇(ze)。

　　首(shou)先，我(wo)們(men)來(lai)看一下在市面(mian)(mian)上常見的外(wai)殼材質。成品外(wai)殼主要包括鋁合(he)金(jin)、不(bu)銹鋼、塑料和(he)玻璃等。考慮到其價格(ge)、質量、使(shi)用壽(shou)(shou)命等因素(su)，不(bu)銹鋼外(wai)殼絕對(dui)(dui)是(shi)上乘之(zhi)選(xuan)。不(bu)銹鋼外(wai)殼不(bu)但耐腐(fu)蝕、表(biao)面(mian)(mian)光(guang)滑、無異味，而(er)且比較輕(qing)(qing)便、易于(yu)清(qing)潔，更重要的是(shi)外(wai)殼壽(shou)(shou)命較長，使(shi)用壽(shou)(shou)命達10年以上。鋁合(he)金(jin)外(wai)殼相對(dui)(dui)較輕(qing)(qing)，同時具(ju)有良好的散(san)熱(re)性。但是(shi)鋁合(he)金(jin)外(wai)殼受潮易生(sheng)銹，不(bu)耐腐(fu)蝕，容(rong)易變形(xing)，使(shi)用壽(shou)(shou)命很(hen)短。因此，我(wo)們(men)應該根據自己(ji)的實際(ji)情(qing)況來(lai)選(xuan)擇。

　　另外，在選擇外殼的時候，還要注意它的做工精良，外殼表面平滑光滑。好的外殼，不僅外觀上好看，而且表面光滑，整體結構緊湊，表面無錯誤。檢查外殼表面無毛刺、磨損、腐蝕，零件與(yu)外殼緊(jin)密吻合(he)，無掉角、掉漆現象。

　　上述是關于成品鋁合金外殼的選擇要點，希望能夠對大家的選擇提供幫助。

　　Although the price of finished aluminum alloy housings is generally more expensive, the number of purchases is not small. According to the actual situation in the market, the quality of finished aluminum alloy housings is different, and the price fluctuates accordingly. Therefore, when choosing, we should choose according to our actual situation.

　　First of all, let's take a look at the common housing materials on the market. Finished housings mainly include aluminum alloy, stainless steel, plastic and glass. Considering the price, quality, service life and other factors, stainless steel housings are absolutely the best choice. Stainless steel housings are not only corrosion resistant, smooth surface, no odor, but also relatively lightweight, easy to clean, more importantly, the life of the housing is long, the service life is more than 10 years. Aluminum alloy housings are relatively light, but also have good heat dissipation. However, the aluminum alloy housing is prone to rust, non-corrosion, easy deformation, and the service life is short. Therefore, we should choose according to our actual situation.

　　In addition, when choosing the housing, we should also pay attention to its fine workmanship, the surface of the housing is smooth and smooth. A good housing not only looks good in appearance, but also has a smooth surface, compact structure, and no surface errors. Check that the surface of the housing has no burrs, wear, corrosion, parts and housing fit snugly, no corner, paint shedding.

　　The above is about the key points of choosing finished aluminum alloy housings. I hope it can help you with your choice.
