Lead Semicircular Cross Section, Rounded Ends Bar

Goodfellow’s Lead Bar has a unique semicircular cross-section and rounded ends. With its exceptional purity of up to 99.999%, it’s perfect for applications requiring high precision and reliability. Lead is a soft, silvery white or grayish metal, that’s very malleable, ductile and dense. It is also a poor conductor of electricity while being highly resistant to corrosion. These properties make it good for radiation shielding, as well as for vibration dampening and other applications.
