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同，價格也隨之波動。因此，在選購的時候，我們應該根據自己的實際情況來選擇。

　　首先，我們來看一下在市面上常見的外殼材質。成品外殼主要包括鋁合金、不銹鋼、塑料和玻璃等。考慮到其價格、質量、使用壽命等因素，不銹鋼外殼絕對是上乘之選。不銹鋼外殼不但耐腐蝕、表面光滑、無異味，而且比較輕便、易于清潔，更重要的是外殼壽命較長，使用壽命達10年以上。鋁合金外殼相對較輕，同時具有良好的散熱性。但是鋁合金外殼受潮易生銹，不耐腐蝕，容易變形，使用壽命很短。因此，我們應該根據自己的實際情況來選擇。

　　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，零件與外殼緊密吻合，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.
