Lead Sheet Metal
Lead sheet provides excellent radiation shielding capability with high density (11.34g/cm³), and 10mm thickness can block more than 99% of X/γ rays. It has excellent ductility (ductility ≥45%), supports cold bending and bonding of complex structures, and is easy to construct. It is resistant to strong acids and alkalis (pH 2-12), has a corrosion resistance life of more than 20 years, and is suitable for chemical corrosion protection scenarios. It is 100% recyclable, meets RoHS environmental protection standards, and has no pollution risk. It has both sound insulation and noise reduction functions (30dB+), and has outstanding comprehensive cost performance, making it a core material for medical and nuclear industry protection.
