Tungsten needles are relatively inflexible compared to some other materials due to their high tensile strength and hardness. However, their flexibility can be increased by decreasing the diameter of the needle or by increasing the length-to-diameter ratio. In general, materials with lower tensile strength and hardness, such as some metals and polymers, can be more flexible than tungsten needles. However, these materials may not be as suitable for certain applications where high strength and hardness are necessary.
