This is an A2017 aluminum round bar. φ60mm (6 cm) with a length of approximately 175mm, there are 3 pieces. Plus or minus 5mm. This is a high-strength, free-cutting Cu-based alloy, often referred to as duralumin. However, it has poor weldability and corrosion resistance, so please choose accordingly. The price is for the three pieces shown in the image. The surface is unfinished. There are some scratches and dents. Also, the cut surfaces have not been deburred, please be aware of this. I am not a business, so I do not sell cut pieces. There are no material certificates. Please bid only if you understand this. Shipping is planned via宅配便 (courier service). I will use cushioning material and recycled cardboard boxes for shipping. Thank you for your understanding.
