This is an A2017 aluminum round bar. φ20mm (2 cm) with a length of approximately 125mm (12.5 cm), 5 pieces in total. The tip has some remaining machining marks. There are variations in length. These are scrap aluminum materials. There may be dents or pressure marks. If you have a lathe, how about using these to create parts? We are not responsible for any damages or accidents that may occur from using this material. Please understand. This is a Cu-based alloy with high strength and excellent machinability, often referred to as duralumin. However, it has poor weldability and corrosion resistance, so please choose accordingly. The price is for the 5 pieces shown in the image. The surface is unfinished. There are some scratches and dents. Also, the cut surfaces have not been deburred, please understand. We are not a business, so we do not sell cut pieces. There are no material certificates. Please purchase only if you understand this. Shipping is planned via Yu-Packet Post Mini. Due to thickness restrictions, we will secure the items with masking tape on cardboard.
