The Ultimate Tungsten Buyer's Guide
Tungsten is a metal of extremes. Whether you are a scientist, a welder, or a collector, understanding these properties is key to your purchase.
1. Density vs. Hardness
One of the most common mistakes is confusing Pure Tungsten with Tungsten Carbide.
- Pure Tungsten: Best for weight (19.3 g/cm³). Ideal for cubes and spheres.
- Tungsten Carbide: A composite used for industrial hardness. It is harder than steel but roughly 25% less dense than the pure metal.
2. The "Kilo" Standard
The 1kg Cube is the industry favorite for desktop displays. Despite its massive weight, it measures only about 1.5 inches, creating a unique sensory "mind-flip" when you pick it up.
3. Industrial Rods & Wire
Industrial rods are typically 99.95% pure and used for machining precision parts. For welding, ensure you look for color-coded TIG Electrodes. Tungsten wire is specialized for high-heat environments like vacuum evaporation due to its 3,422°C melting point.
