AJMRTC Pure Solid Copper Rod, 99.9% High Purity Copper Bar 4mm Diameter 100mm Length, Industrial Brass Copper Solid Round Rod for Metal Craft, DIY Model, Welding, Electrical Conductive Experiment Proj

AJMRTC highpurity solid copper round rod is manufactured from 99.9% pure copper material, featuring remarkable electrical and thermal conductive properties. Each copper rod measures 4mm in diameter and 100mm in length, solid construction without hollow cavity. The surface is smooth with fine workmanship, offering great ductility so you can cut, bend, grind or drill according to your actual project requirements. This pure copper bar is widely applied in multiple scenarios: electrical conduction experiments, DIY model production, metal handicraft making, welding auxiliary material, mechanical part repair and smallscale industrial processing. Please keep the copper rod stored in dry environment to slow down surface oxidation. Minor color darkening caused by oxidation is normal for pure copper and will not affect its core performance. Confirm diameter and length match your project needs before purchasing.
