Common density detection methods include weighing method, specific gravity cup method, Archimedes' principle method, buoyancy method and drainage method, etc. When detecting the density, the zinc alloy or aluminum alloy material is weighed and then immersed in water. The error in the measurement will lead to density error and misjudgment of the density value. The measurement error makes it difficult to distinguish the density values ​​of two materials that were originally close, which may lead to material identification errors. Slight density differences may determine the type of material and its economic value. Incorrect density judgment may lead to waste of resources or economic losses.
