日本研制铝基防震合金日本三菱金属公司研制成功一种特别适合汽车使用的铝基防震合金。该合金采用６０５铝、３３％锌和６％硅压铸而成，密度达到３．４ｇ／ｃｍ３。虽然密度比普通铝合金大一些，但由于液态流动性好，可制成薄壁铸件，因此并不如大铸件自重。而目该合金在... Japan developed aluminum-based shockproof alloy Japan’s Mitsubishi metal company successfully developed a particularly suitable for automotive use aluminum-based shockproof alloy. The alloy is die-cast from 605 aluminum, 33% zinc and 6% silicon with a density of 3.4 g / cm3. Although the density is larger than ordinary aluminum alloy, it is not as heavy as heavy castings due to its good fluidity and thin-walled castings. And the purpose of the alloy in ...
