Classification of materials
Materials for manufactured parts or machines have such diversified properties that even when performance and cost are considered, it is often difficult to decide the proper material for a given purpose. One material may have higher strength , another better corrosion properties ，and yet another may be more economical. Hence, most choices are a compromise among a number of materials using the best engineering data and judgment available. Copper, for example, may be alloyed in hundreds of ways to produce materials with special properties.
In general, materials may be classified as follows
Table 1-2 shows the principal meals used in manufacturing processes and a few of their important physical properties. The values indicate the approximate range of properties that can be expected depending on alloying and heat treatment. Other important commercial metals include tin, silver, platinum, manganese, vanadium, and titanium. Because special properti

材料分类
材料制造的部件或机器等多种性能，即使在性能和成本的考虑，往往难以作出决定的适当材料某一目的。一个材料可能有更高的强度，又更好的防腐性能，并且又可以更经济。因此，大多数选择的是一个相互妥协的一些材料使用最好的工程数据和判断提供。铜，例如，可能是合金数以百计的方式生产材料的特殊性能。
一般情况下，材料可分类如下
表1-2显示的主要膳食用于制造过程和一些重要的物理特性。值的大致范围说明的特性，可以预期取决于合金化和热处理。其他重要的商业金属包括锡，银，铂，锰，钒，钛。由于特殊的性质可以得到合金，很少有纯金属广泛使用。
有色金属普遍低劣的实力，但在耐腐蚀性能优于相比有色金属材料，而且大多数是更加昂贵。
非金属材料（表1-3 ）被列为有机如果它们包含动物或植物细胞（死的或活的）或碳化合物皮革和木材的木材都是例证。材料被列为无机如果他们以外的其他动物，植物，或碳轴承。
有根本分歧有机和无机材料。有机材料通常会溶于有机液体，如酒精或四氯化碳，但他们不会在水中溶解的无机材料往往溶于水。一般来说，无机材料抗热比更有效的有机物质。
一些材料是必要的，制造成品。选择金属和非金属之间的有机和无机材料是一种折衷的服务特点和成本。为了提高汽油里程数，提供的材料最重的一部分已获得青睐。
