常见的手电金属材料：
Common flashlight metal materials:
1、铝：铝合金是最常用的手电外壳材料。
1. Aluminum: aluminum alloy is the most commonly used flashlight shell material.
好处：磨光容易，不易锈蚀，重量轻，塑性性好，加工相对容易，在表面进行阳极电镀处理后，能获得良好的耐磨性和颜色。
Advantages: easy polishing, not easy to rust, light weight, good plasticity, relatively easy processing, good wear resistance and color can be obtained after anodic plating on the surface.
缺陷：硬度低，怕碰撞，容易变形。
Defects: low hardness, fear of collision and easy to deform.
多数组装手电都是用AL6061-T6铝合金材料，6061-T6又称航空硬铝，轻而强度高，生产成本高，有良好的可成形性、良好的抗腐蚀性能，氧化效果较好。
Most of the assembled flashlights are made of AL6061-T6 aluminum alloy. 6061-T6, also known as aviation hard aluminum, is light and high strength, high production cost, good formability, good corrosion resistance and good oxidation effect.
2、铜：常用于制作激光手电或限量版手电。
2. Copper: commonly used to make laser flashlight or limited edition flashlight.
优势：具有优异的散热性，延展性好，电阻率极低，是非常耐久的金属外壳材料，可反复循环，不损伤其机械性能。
Advantages: it has excellent heat dissipation, good ductility and very low resistivity. It is a very durable metal shell material, which can be recycled repeatedly without damaging its mechanical properties.
弊端：重量大，氧化容易，表面处理困难，难以获得高硬度，一般以电镀、喷漆或烤漆为主。
Disadvantages: heavy weight, easy oxidation, difficult surface treatment, difficult to obtain high hardness, generally electroplating, painting or baking.
