This is an A2017 aluminum round bar. φ40mm (4 cm) with a length of approximately 160mm, 6 pieces. There may be a variance of plus or minus 5mm. This is a high-strength, Cu-based alloy with excellent machinability, often referred to as duralumin. However, it has poor weldability and corrosion resistance, so please choose accordingly. The price is for the six pieces shown in the image. The surface is unfinished. There are some minor 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 will be via Takkyubin Compact. ⭐︎ General-purpose lathe, NC lathe, machining center DIY, crafting, cutting, original product creation Aluminum, aluminum round bar, aluminum rod #aluminumroundbar #aluminum #A2017B #17S #roundbar #DIY #material #scrap #roundbar #machineparts #lathe #machining #duralumin
