Driven by consumer upgrades, consumer electronics secondary and multiple consumption become mainstream. In this environment, companies are paying more and more attention to the material technology of products, especially the concept of green environmental protection, and want to use this to improve user experience and brand. Image. Therefore, aluminum alloy profiles are more and more widely used in the home appliance industry. Many white goods use aluminum alloy parts instead of plastic parts to meet modern consumer concepts and aesthetic standards.
At present, the mainstream televisions on the market are basically assembled with aluminum alloy middle frames. In air conditioners, aluminum accounts for about one-tenth of its cost structure; in refrigerators, aluminum accounts for one-twentieth of the cost structure. And with the gradual rise of the current "aluminum copper", the proportion of aluminum in white appliances has continued to increase, driving the widespread use of aluminum in the mass consumer electronics field.
"Aluminium replaces copper" advantage highlights the aluminum boom in consumer electronics
In this regard, Lan Wenhui, deputy general manager of the China Academy of Electrical Sciences / Guangzhou Qingtian Industrial Co., Ltd. has his own views. He believes that "the key to the rise of 'aluminium for copper' lies in cost. At present, the price of aluminum is only about the price of copper. 1/5, the direct benefit brought by the "aluminum copper replacement" to enterprises is the cost reduction. "
In addition, he believes that "aluminium replaces copper" is given a longer-term meaning: "Since China is a copper-poor and aluminum-rich country, the copper used in white goods consumption relies heavily on imports, and the global copper resources are only sufficient for 40 years. From the perspective of energy saving and environmental protection, "aluminum replaces copper" has a broad space for development. Therefore, the development of aluminum alternative raw materials has become one of the industry's priorities in the future. Due to the continuous progress of aluminum processing technology, aluminum has a variety of performances. Meeting the standards of white goods, aluminum consumption continues to grow. "
The consumer electronics market has grown rapidly in recent years, and many consumer electronics products have become shorter and shorter. In addition to the technological innovation of products, the outer packaging of various products is gradually changing from plastic materials to metal materials. Mr. Lan believes that the reason is that the cost of metals is declining, and the products are more lightweight, environmentally friendly, practical and beautiful. Therefore, the collective "shell change" of consumer electronics manufacturers has become a boom.
Based on this, in addition to meeting the performance requirements of electronic products, special attention must be paid to the surface treatment of aluminum alloy processing. There are many surface treatment methods for aluminum alloy, such as: oxidation, coloring, electrophoresis, sandblasting, wire drawing, dyeing, spraying, Electroplating, etc., can be colorful, beautiful and practical, and meet the needs of users and the times to the greatest extent.
Mr. Lan specifically mentioned that the polychromatic inorganic coloring process technology was introduced to China more than ten years ago, but because the reproducibility of coloring is difficult to meet domestic decoration needs, it has not been promoted on a large scale. Secondly, aluminum alloy workpieces in consumer electronics are small and the surface treatment process is easy to control. Furthermore, aluminum alloys in consumer electronics are less sensitive to color dispersion. The weather resistance of inorganic multi-coloring is much better than the organic coloring of dyeing. It is especially suitable for coloring aluminum alloy surfaces such as automobile decoration parts and outdoor or semi-outdoors. It can meet the personalization of electronic products with rich colors and good weather resistance. Demand.
