In the past 20 years, with the rise of China's manufacturing industry and the transfer of the world's manufacturing center, China has become the world's manufacturing center, and the global winding wire market has gradually shifted to China; the output of winding wire has surpassed that of the United States and Japan, and become the world's largest producer and consumer; the output of winding wire has exceeded that of the United States and Japan, and become the world's largest producer and consumer;
 
In recent years, China's winding wire manufacturers have expanded their production scale through investment and asset restructuring
 
In the trend of international economic integration, China's advantage of low-cost manufacturing has attracted the transfer of foreign manufacturing industry to China, so the supporting winding manufacturing industry has also begun to transfer to China; foreign companies have been expanding their manufacturing scale in China; foreign companies have been building factories in China, and the manufacturing scale has been expanding.



The main advantages of aluminum winding wire are low cost, low price, abundant resources, low cost, low price, abundant resources, low logistics cost; the main disadvantages are aluminum winding line production technology, low tensile strength, easy to break in the process of drawing, the main disadvantages are aluminum winding wire Production process problems, low tensile strength, easy to break during drawing; in addition, hardness and wear-resistant properties are not as good as copper, and the surface is easy to be scratched. There are many bright spots, beads and aluminum spots on the surface of the coating line; too many pinholes on the surface of aluminum paint will cause motor bright spots, beads and aluminum spots; too many pinholes on the surface of aluminum paint will cause motor temperature rise, which is serious It will lead to the failure of the motor; the adjustment of equipment, tooling, process and other problems will lead to the difficulty of processing; the problems of follow-up products, lead joints are difficult to weld; the resistivity of aluminum is higher than that of copper, so in the design of motor and electrical appliances, to achieve the same output rate and efficiency as copper, the section and length of aluminum wire must be increased, resulting in the increase of the volume of follow-up products, and the increase of other supporting materials More importantly, the increase of resistivity also increases the energy consumption, so the long-time operation of slide 22 increases, more importantly, the increase of resistivity also increases the energy consumption, so the use of aluminum winding wires for long-time operation of motors and electrical appliances is limited;
 
Driving factors: cost driving of downstream customers, pressure of price competition and capital pressure; enthusiasm for downstream industries that are highly sensitive to cost; enthusiasm for downstream industries that are highly sensitive to cost; relatively inadequate competition for aluminum winding manufacturers; small capital occupation and low financial cost; high investment intention; substitution level of about 60-100kt The scale is about 120 ~ 200kt, the scale is about 60 ~ 100kt, the scale is about 120 ~ 200kt, the potential space is large;

All or part of the alternative fields have been replaced, mainly focusing on the occasions with less consideration of energy consumption and short-term use, such as microwave transformer and reactor, microwave transformer and reactor, TV degaussing coil, industrial fan motor, industrial sewing machine motor, industrial sewing machine motor, ups and power supply, small household motor (such as bottle opener, juice blender Mixer, water pump motor, fan Changer) • for household fan motor, air conditioner motor, SP motor, washing induction motor, lighting ballast, power transformer / power adapter, ring transformer, reactor, electroacoustic device, electroacoustic device, welding machine, cover pole motor, power transformer (auxiliary transformer has been adopted) slide 24, power transformer (auxiliary transformer has been adopted), freezer compressor, air conditioner Compressor and refrigerator compressor (tracking verification)
