Aluminum bronze
Copper has excellent electrical and thermal conductivity, ranking the highest of all engineering metal materials, which is the main basis for its pivotal role in the current generation electrification and electronic information society. Copper There are many excellent performance: its atmosphere, water, soil, and many chemical mediators have strong corrosion resistance; it is used in the structural hardness with softness, elasticity, friction, wear-resistant; it has a colorful The appearance is that people loved, simple and elegant symbol. In addition to the numerous performance, but it also has a good range of machining, casting, welding, cutting and other process performance, so that it gained economic and widely used.
