VMT 2024 07 04 The melting point, the fixed temperature at which a substance transitions from a solid to a liquid state, is a fundamental concept in materials science. For metallic materials, the melting point is directly related to machining difficulty, operating temperature range, and thermal stability. As an alloy of copper and zinc, the melting point of brass varies depending on its composition.

VMT 2024 07 03 Brass, an alloy of copper and zinc, has distinct physical and chemical properties compared to pure copper or zinc. Importantly, brass does not contain iron, meaning it does not rust in the same way iron does (i.e., forming iron oxide). However, brass can undergo a chemical process called "oxidation" under certain conditions, leading to a change in surface color and the formation of a dark yellow or greenish oxide layer, often mistaken for rust.
