2025 12 17 Lead does not rust because rust is specific to iron. However, lead does corrode and oxidize when exposed to air, moisture, acids, or sulfur compounds. This lead oxidation process forms a thin protective layer that slows further damage, giving lead relatively high lead corrosion resistance compared to many other metals.

VMT 2025 12 17 When you plan to manufacture metal parts with thinner walls and higher machining difficulty, there are usually two common manufacturing methods to consider: CNC machining and thin-wall casting. So, to deal with different materials, wall thicknesses, precision requirements, and applications, how would you choose between CNC machining and thin-wall casting? But like any manufacturing process, you need to learn a lot before deciding which process works best for your parts. This article will guide you through CNC machining and thin-wall casting, including their definitions, pros and cons, recommended wall thickness ranges, typical applications, as well as cost factors, helping you clarify whether they are the right processes for your project.

VMT 2025 12 16 The melting point of magnesium is approximately 650°C (1,202°F). This magnesium melting temperature is lower than many structural metals, making magnesium easy to melt but sensitive to heat. In CNC machining, careful thermal control is required to prevent deformation, oxidation, or ignition.
