In the past few decades, YTFX Bimetal Material Technology Group has cooperated with the team of Academician Xie of University of Science and Technology Beijing to successfully realize the inventions of “Copper Aluminum Composite Material Continuous Casting Direct Forming Technology and Process” and “Composite Busbar Efficient Forming Technology and Process” The industrialization of expert achievements, undertaking the national “863 Program” twice, and taking the lead in drafting two national standards and one international standard in the field of continuous casting copper-aluminum composite materials.
Why can YTFX’s copper-aluminum composite materials be selected into China’s national “863 Program” and become a drafter of national and even international standards? What technical advantages does Fuxinda have?
From the perspective of national resource security, China accounts for more than 40% of the world’s annual copper consumption, but 75% is dependent on imports. China`s electric power sector consumes nearly 2 million tons a year. If copper-aluminum composite materials are used for replacement, and aluminum is used to save copper, it can save the country 1.5 million tons of pure copper resources each year, which is of great significance to safeguarding national resource security.
“Our copper-aluminum composite conductor material has a volume conductivity of 75%, and a current carrying capacity of 80% of pure copper of the same specifications. Compared with copper, it reduces weight by 50% and can reduce costs by about 30%. Our core advantage is copper and aluminum. The metallurgical bonding between atoms solves the transition problem of copper-aluminum transition.” YTFX’s CTO explained to Hay Think.

The main feature of YTFX’s copper-aluminum composite material is its lightweight advantage. The product can increase the overall energy-to-weight ratio of the battery pack and increase the cruising range. Take new energy vehicles as an example. At present, the connection of YTFX products on each new energy passenger car is about 5 kg, and each new energy bus uses about 50-70 kg, which saves about 50% of the weight.
The subway and high-speed rail car bodies are made of aluminum alloy materials, and the power distribution system is made of copper materials. The grounding safety connection between copper and aluminum used to be imported from the United Kingdom. Now YTFX’s copper-aluminum composite materials have realized a real import substitution. While lowering the price, it also achieved performance improvements.
In the field of electric power fittings, it is estimated that there will be about 10,000 tons of copper-aluminum transition material demand every year, and the market size will exceed 1 billion yuan. The previous power fittings products used friction welding, and there was a risk of fracture under the painful heat and vibration conditions, and there was a high risk to the safety of the entire power grid and the maintenance of the power grid, and the cost was high. YTFX’s newly developed “new copper-aluminum transition terminal” product (commonly known as wire nose) solves the long-term unreliable service problem caused by direct welding of copper and aluminum in the field of power fittings, and effectively promotes the transformation and upgrading of the power fittings industry and the safe and continuous operation of the power system .
Since YTFX products were introduced to the market in 2012, they have quickly gained market recognition. At present, more than 20 leading domestic and foreign companies such as Goldwind, ABB, Schneider, etc. have adopted the copper-aluminum composite busbars produced by YTFX company instead of pure copper busbars for transmission and distribution. The electrical equipment has been tested and its performance fully meets the requirements for use. The company now has an annual production capacity of 8,000 tons of copper-aluminum composite materials.
