[Carbon Neutral Processing Case] Development of Processing Technology for Duralumin

[Carbon Neutral Initiatives - Specific Examples] Achieved a 60% weight reduction through the development of processing technology for duralumin!

【Carbon Neutrality Case Study】 Replacing parts originally made of high-tensile strength steel (590 material) with high-strength aluminum for carbon neutrality: A challenge towards weight reduction. This results in a 60% weight reduction compared to high-tensile materials. If processed at room temperature, the material would crack and be unprocessable. However, by focusing on the aging characteristics of duralumin, a processing method was developed that improves formability while maintaining material strength, successfully allowing for product processing. Nonetheless, there are still many challenges, such as determining the processing limits for each method, and evaluating the precision and strength of the products, especially since cracks can occur during bending if the bending radius is too small.
