电动车公社·2025-12-15 16:05Core Viewpoint - The automotive industry is experiencing intensified competition, leading to concerns about potential compromises in quality as prices decrease [1][2]. Group 1: Material Development and Innovation - The company hosted a Material Technology Day to address concerns about quality amidst competitive pricing [2][3]. - During the event, the company showcased two fuel tank samples, one made from their self-developed stainless steel "UFHS-X" and the other from commonly used 304L stainless steel, highlighting the differences in durability [19][24]. - The development of the UFHS-X material involved significant investment, with over 1,000 tons of steel consumed and more than 300 puncture tests conducted over four years, resulting in a cost of over 10 million yuan [27][25]. Group 2: Safety and Material Strength - The company emphasizes that higher material strength does not directly equate to higher safety, as seen in their findings regarding the use of 2000MPa hot-formed steel, which posed safety risks due to its brittleness [31][36]. - A new high-toughness high-strength steel "2000IH" was developed in collaboration with Tsinghua University and Ma'anshan Steel, balancing strength and ductility for better energy absorption during collisions [44][49]. Group 3: Collaboration and Industry Contribution - The company collaborates with leading material firms, such as Novelis, to optimize aluminum alloys for battery protection, resulting in the development of "LeS6 Ultra" aluminum alloy, which enhances puncture resistance and reduces deformation [55][59]. - The company is open to sharing its self-developed materials with competitors, contributing to the overall safety development of the new energy vehicle industry [29][30]. Group 4: Comprehensive Material Science Approach - The company is also focusing on interior materials, utilizing self-lubricating POM materials and collaborating with companies to reduce formaldehyde emissions in vehicle interiors [62][65]. - The ongoing exploration of material science is seen as crucial for the automotive industry's growth and innovation, pushing beyond existing limitations [69].
