The biggest difference between tungsten and lead weights is their density. More answers below Meave Gilchrist It can however develop a gray patina which only affects its appearance. A lead shield will be thinner than a steel (21.6 HVL) or concrete (60.5 HVL) shield of the same effectiveness in shielding a Co60 source. Twenty-five pounds of lead would be 6.40 long. This density is much higher than that of lead. For example, you can determine if you're fishing over small gravel as opposed to larger chunk rock. The density of this metal is far more comparable with that of gold and uranium chemical elements. That disqualification gave the win to Erik Jones, There is a trend now of making jewelry from tungsten and tungsten alloys, which raises a big problem. Required fields are marked *. Lead metal has several useful mechanical properties, including high density, low melting point, ductility, and relative inertness. It's dense enough to use as a lead alternative to shield from radiation, a vibration dampener in small spaces for equipment such as helicopter blades, and as crankshaft weights. Its density also means it won't lose its shape under extreme conditions. The single tungsten cylinder on top weighs .5 oz and is 7/16" long. The density helps it use a small volume while still providing water resistance. Yeah, you just accidentally have a $2000 block of metal laying around when a $100 chunk would do.
