Tungsten Rhenium Alloy Features
- High Melting Point: Tungsten rhenium alloy has a very high melting point, suitable for use at extremely high temperatures.
- High Strength and Hardness: Tungsten rhenium alloy can still maintain excellent mechanical strength and hardness under a high-temperature environment.
- High Plasticity: Compared with pure tungsten, tungsten rhenium alloy has better ductility and processing performance.
- High Recrystallization Temperature: Tungsten rhenium alloy has a high recrystallization temperature and can maintain a stable crystal structure at high temperatures.
- Low Toughness and Brittle Transition Temperature: Tungsten rhenium alloy can still maintain good toughness at low temperatures, and is not easy to brittle crack.
Tungsten Rhenium Alloy Production Process
- Mixing: The tungsten powder is mixed with rhenium in the desired proportions.
- Pressing: The mixed powder is pressed into the desired preliminary shape, such as cylinders, blocks, etc.
- Frittage: The pressed parts are sintered at high temperatures, forming a dense solid material.
- Recuit: The sintered products undergo an annealing process to remove internal stresses and improve toughness and ductility.
- Machining: Precision machining processes, such as turning, milling, and grinding, are applied to the sintered parts to achieve final dimensions and shapes.
- Traitement thermique: The alloy undergoes additional heat treatment to optimize properties such as hardness, strength, or other physical characteristics.
- Traitement de surface: If required, surface treatments (such as coating, passivation, etc.) are applied to enhance corrosion resistance, hardness, or other properties.
