Comparison of the state and properties of tungsten and tungsten alloy materials
| Material Status | Process Description | Typical Performance Characteristics |
| Sintered | The powder is pressed into a compact shape and then sintered at high temperature, representing the most basic form. | It has a relatively high density (typically reaching 92-98% of the theoretical value) and high hardness, but contains residual pores internally, resulting in low plasticity and toughness, and limited strength and ductility. |
| Forged | The sintered blank is subjected to plastic deformation processing at high temperatures. | It significantly improves density (approaching 100%), refines grain size, and substantially enhances tensile strength, toughness, and impact resistance, exhibiting pronounced anisotropy. |
| Rolled | Directional deformation is achieved through rolling mills (commonly used for sheets and rods). | Higher strength and hardness (due to work hardening), exhibiting distinct directional properties (longitudinal properties are superior to transverse properties), and a good surface finish. |
| Annealed | The cold-worked material is heat-treated under a protective atmosphere. | This process eliminates internal stress, reduces hardness, improves plasticity and toughness, restores some ductility, facilitates subsequent cutting or forming processes, but sacrifices some strength. |
If you are unsure how to select the appropriate material condition, please provide your application scenario, loading conditions, subsequent processing techniques, and performance priorities (e.g., strength vs. machinability). Our technical team can recommend the best conditions for you and develop the corresponding heat treatment and machining process route.
