Ordinary LEGO bricks are made from molded plastic. For something with more substance, check out these cool metal building blocks from ScrappersOutpost. The CNC-machined bricks interlock just like the real deal too. They come in aluminum, brass, or copper, and there are discounts for buying multiples. They also make a keychain version.
