The mechanical properties of tungsten alloys refer to the mechanical characteristics of alloy materials under various external loads in different environments and are the main basis for determining various engineering design parameters, mainly including hardness, brittleness, plasticity, toughness, and tensile strength. Strength, Yield Strength, Elasticity, Ductility, Rigidity, etc.
1. Hardness
It refers to the ability of the alloy material to locally resist the pressing of hard objects into its surface. It is an important mechanical performance index to measure the softness and hardness of the material. It can be measured by methods such as Brinell hardness, Rockwell hardness, Vickers hardness, and microhardness. The hardness of tungsten alloy is generally 24~35HRC.
2. Brittleness
It refers to a characteristic of material fracture and damage under the action of external force. It is contrary to toughness and plasticity and is related to factors such as material composition, raw material ratio, and organizational structure. For tungsten-nickel-iron alloy or tungsten-copper alloy, generally with the increase of tungsten content or the decrease of binder metal (such as nickel, iron, copper) content, the brittleness of the alloy will also increase.
3. Toughness
It refers to the ability of a material to absorb energy during plastic deformation and fracture and refers to the resistance of a material to fracture when it is subjected to a force that causes it to deform. It is the opposite of brittleness. In tungsten-based alloys, the binder phase mainly provides toughness, so under certain conditions, the higher the binder phase content, the better the toughness of the alloy, and the lower the possibility of brittle fracture.
Baoji Yusheng Metal Technology Co., Ltd. believes that no matter what kind of mechanical properties, they are affected by factors such as material composition, raw material ratio, organizational structure, production process, and post-processing.
