In order to reduce costs, washing machine companies have been trying to make aluminum wire motors achieve the same effect. However, the relevant test results show that compared with copper wire motors, the temperature of aluminum wire motors is higher during use, which will affect the service life. Aluminum wire motors have only appeared in the past five or six years. In recent years, the price of copper has continued to rise, while the price of aluminum has basically remained at about one-fifth of the price of copper. However, the washing machine motor standard does not limit the materials used in the product, and the impact of aluminum wire motors on performance is currently within the national standard pass line.
As the main raw material for the upstream of home appliances, the rise in copper prices is putting a lot of pressure on companies. How to replace copper with new materials has become an urgent task for enterprises. In the first half of 2011, the domestic copper price basically remained above 70,000 yuan / ton, up 9% from the same period in 2010 and 60% higher than the same period in 2009. The dispute between copper and aluminum on air-conditioning and gas water heater products has been settled, and relevant tests have shown that the use of aluminum alloy components will not affect the use of the product, or even improve the performance of the product. However, the current use in washing machines There is no technical breakthrough in aluminum wire motors. Industry insiders generally believe that copper prices will remain high in the second half of the year, and that China is a copper-poor and aluminum-rich country. Copper used in the production of home appliances relies heavily on imports. Therefore, the development of aluminum alternative raw materials will become the focus of the future. In the washing machine industry, aluminum wire motors instead of copper wire motors are gradually being used in low-end products by some small enterprises in Jiangsu and Zhejiang and some large enterprises. Taking a two-cylinder washing machine as an example, the use of aluminum wire motors can save more than ten yuan in cost than copper wire motors. This part may be the profit of the enterprise.
