Summary of Conference Call on JinTian Co., Ltd. and Aluminum-Copper Substitution Trend Industry Overview - **Aluminum-Copper Substitution Trend**: The price ratio of copper to aluminum has expanded to nearly 1:5, indicating a shift from concept to practical application, particularly in the air conditioning industry. Domestic and international companies are actively exploring this transition [2][3]. - **Air Conditioning Industry Application**: Major overseas companies like Daikin are leading in microchannel flat tubes and parallel flow heat exchanger technologies. In contrast, domestic companies are focusing on using internally threaded round aluminum tubes to replace copper tubes, although issues related to corrosion resistance, heat exchange, and drainage still need to be addressed [2][4]. Key Points and Arguments - **Challenges of Aluminum-Copper Substitution**: Downstream manufacturers face significant equipment modification costs, and consumer misconceptions about aluminum being inferior could hinder acceptance. Companies like Midea and Xiaomi are collaborating to promote this change [2][6]. - **Prospects for Internally Threaded Aluminum Tubes**: It is expected that the replacement of copper tubes with aluminum tubes will gradually occur over the next few years, with potential completion in two to three years if all parties collaborate effectively. National policies are supporting this shift to reduce reliance on imported resources [2][7]. - **Impact of Copper-Aluminum Price Ratio**: The domestic copper-aluminum price ratio has reached a historical high of 4.3, significantly affecting cost control. Replacing copper with aluminum in air conditioning units can reduce costs by approximately 400 RMB per unit, making it more attractive in the mid-to-low-end market [2][12]. Additional Insights - **Long-term Copper Price Trends**: Short-term copper prices are unlikely to decline significantly, which encourages companies to consider aluminum as a cost-effective alternative, potentially leading to a demand loss of two to five million tons of copper in the long run [4][17]. - **Current Production Capacities**: Monthly copper tube production is around 25,000 tons, while the largest aluminum tube manufacturers produce only a few hundred tons per month, indicating a significant disparity in production scales [23]. - **Technological Innovations**: JinTian Co., Ltd. has developed advanced aluminum tube production technologies, including zinc plating to enhance corrosion resistance. These innovations are expected to meet national energy efficiency standards and ensure good weldability [10][33]. Future Outlook - **Market Penetration of Aluminum-Copper Solutions**: The penetration rate of aluminum solutions in the air conditioning market is expected to increase gradually, with significant growth anticipated if major manufacturers like Midea undertake large-scale production line modifications [14][21]. - **Company Strategies**: JinTian Co., Ltd. is focusing on high-standard aluminum tube production lines and enhancing collaboration with downstream customers to promote market acceptance and consumer education [4][9]. The company is also diversifying into high-margin sectors like electric vehicles and semiconductors [4][31]. This summary encapsulates the key discussions and insights from the conference call regarding the aluminum-copper substitution trend and its implications for the air conditioning industry and JinTian Co., Ltd.

Summary of Conference Call on JinTian Co., Ltd. and Aluminum-Copper Substitution in the Air Conditioning Industry Industry Overview - The air conditioning industry is experiencing a shift from copper to aluminum due to high copper prices, with aluminum offering significant cost advantages. For instance, a 1.5 HP air conditioner can save over 300 yuan by using aluminum instead of copper [2][6]. - The current usage of aluminum in the air conditioning sector is minimal, with projections indicating that by 2025, aluminum pipes will account for less than 5% of the market [2][9]. Key Points and Arguments - **Technological Challenges**: The transition to aluminum is hindered by technical barriers such as corrosion resistance, weldability, and energy efficiency. These issues need to be addressed for widespread adoption [3][6]. - **Production Line Transition**: Switching production lines from copper to aluminum typically takes 12 to 16 months, resulting in a 40%-50% reduction in capacity during the transition [10]. This aligns with the expected decrease in aluminum usage per air conditioner [10]. - **Market Acceptance**: While manufacturers are optimistic about aluminum, consumer acceptance remains a critical factor. There is a perception that aluminum may be seen as a cost-cutting measure, necessitating industry-wide efforts to mitigate brand damage [6][7]. - **Future Projections**: If market acceptance increases and technology matures, it is anticipated that within 3-5 years, 1/3 to 1/2 of copper pipes will be replaced by aluminum pipes [2][16]. Company Initiatives - **JinTian Co., Ltd. Plans**: The company plans to build a state-of-the-art fully automated production line for internal threaded aluminum pipes in Guangdong and convert some existing copper pipe production lines to aluminum [5][17]. - **Production Capacity**: The first new production line is expected to be operational by the end of 2026, with a capacity of 10,000 tons [17]. However, the industry as a whole is cautious about large-scale aluminum production due to uncertainties in market transition [17]. Market Dynamics - **Commercial vs. Domestic Markets**: The commercial and overseas markets are advancing faster in adopting aluminum materials compared to the domestic household market, where consumer psychology and competition slow down the transition [14]. - **Current Production Statistics**: In 2025, the estimated production of internal threaded aluminum pipes will be less than 10,000 tons, while copper pipe production is projected at 2 million tons [8]. Additional Insights - **Welding and Reliability**: Welding issues have largely been resolved, allowing for better integration of aluminum in air conditioning systems. Collaborative efforts with clients have addressed surface treatment and corrosion resistance [20]. - **Certification Processes**: The certification process for manufacturers varies, with overseas firms facing longer timelines compared to domestic ones. However, established relationships with manufacturers can expedite this process [22]. Conclusion The air conditioning industry is on the brink of a significant material shift from copper to aluminum, driven by cost considerations and technological advancements. JinTian Co., Ltd. is positioning itself to capitalize on this trend through strategic investments in production capabilities, although challenges related to consumer acceptance and production transition remain critical factors for success.
