Practical applications

When discussing practical applications, it's important to differentiate between full-mold applications and partial (insert) usage. Mold Inserts: Rather than making entire molds from tungsten block, manufacturers often use tungsten alloy inserts at high-wear or high-temperature zones within steel molds. This hybrid approach combines the cost-effectiveness of steel with the durability of tungsten where it matters most. Core Pins and Sleeves: In parts of the die that experience the most thermal shock, like core pins, sleeves, and sprue bushings, tungsten heavy alloys show exceptional performance, reducing wear and heat checking. Prototype Molds: Although costlier than traditional mold materials, tungsten bricks can be invaluable for short-run, high-precision projects where mold performance is critical. Specialized Die Casting Applications: For highly corrosive metals or parts requiring ultra-tight tolerances, tungsten-based molds offer unmatched performance.
