2025 12 11 The density of tungsten is approximately 19.254 g/cm³, making it one of the heaviest metals used in industry. Its high tungsten metal density allows for compact, durable components ideal for CNC machined parts. By understanding its weight per unit volume and specific gravity, you can optimize design, reduce material waste, and improve performance in demanding applications.

VMT 2025 12 10 Gold does not rust because it doesn’t react with oxygen or moisture. However, gold alloys can tarnish, corrode, or discolor when mixed metals react with sweat, chemicals, or salt water. To keep gold surfaces bright, clean them regularly, avoid harsh chemicals, store them properly, and use protective coatings when needed.

VMT 2025 12 09 Nickel does not rust the way iron does. Instead of forming reddish-brown rust, nickel creates a thin, protective oxide layer. This nickel surface oxidation slows down nickel corrosion and keeps the metal stable. Pure nickel has strong rust resistance, while nickel alloys—like Inconel, Monel, and Hastelloy—offer even better protection. Only nickel-plated steel may rust if the coating gets scratched or worn off.

VMT 2025 12 08 The melting point of bronze usually falls between 850°C and 1,050°C (1,562°F–1,922°F), depending on how much tin, aluminum, or silicon is in the alloy. You often hear terms like bronze melt point, bronze fusion point, or bronze liquefaction point—all referring to the temperature where bronze becomes fully molten and ready for casting, forging, or high-temperature fabrication.

VMT 2025 12 04 The density of bronze usually falls between 7.4 and 8.9 g/cm³, depending on the alloy blend and how it is processed. When you divide the mass of a bronze component by its volume, you get its bronze material density. This helps you estimate bronze weight per cubic centimeter and choose the right alloy for CNC machined bronze parts or bronze castings.

VMT 2025 12 01 If you’re choosing a material for a part's design, will you imagin that the part will maintain its shape under actual working conditions without permanent bending? Or you may think about whether it will deform under load but not break? Or you are worried that it will fail by breaking directly under extreme conditions? To answer these practical questions , you’ll need to learn about the difference between yield strength and tensile strength. This article will guide you through the difference between yield strength and tensile strength from the perspectives of definition, stress-strain curves, and their impact on part structural design. After reading, you will understand why yield strength and tensile strength are two important evaluation references in industry.
