Products Description
Tungsten Machined Parts refers to tungsten metal components manufactured through high-precision machining processes according to customers' specific requirements. Tungsten is a rare metal known for its extremely high melting point (3422°C), density (19.3 g/cm³), and strength, making it indispensable in many industrial fields. These custom parts can be produced using various machining methods, including electrical discharge machining (EDM), laser cutting, waterjet cutting, CNC milling, turning, drilling, and grinding. The machined tungsten components can achieve exceptionally high precision, typically with tolerances within ±0.0005 inches. Additionally, surface treatment processes (such as polishing, coating, etc.) can further enhance their performance and service life.
