The mechanical properties of tungsten alloy plates can vary based on their composition, which typically includes tungsten along with elements like nickel, iron, or copper. Here are general ranges for some key mechanical properties:
Hardness: Tungsten alloy plates are known for their high hardness, which can range significantly depending on the alloy composition and processing methods. Typical hardness values can range from 25 HRC (Rockwell C scale) for softer alloys to over 40 HRC for harder alloys used in tooling and high-strength applications.
Tensile Strength: Tungsten alloys have excellent tensile strength, typically ranging from 700 MPa (megapascals) to 1200 MPa or higher, depending on the composition and processing. This high tensile strength makes them suitable for structural and high-strength applications.
Elongation: The elongation (or ductility) of tungsten alloys tends to be relatively low compared to other metals, typically ranging from 1% to 10%. This means they are less ductile and more prone to fracturing under tensile stress compared to materials like steel or aluminum.
Yield Strength: The yield strength of tungsten alloys can vary widely depending on the specific alloy composition and heat treatment, but it generally ranges from 500 MPa to 1000 MPa or higher. Yield strength indicates the stress at which a material begins to deform plastically.
Modulus of Elasticity: Tungsten alloys have a high modulus of elasticity, typically around 300 GPa (gigapascals) to 400 GPa. This high modulus indicates their stiffness and ability to resist deformation under applied stress.
Impact Strength: Tungsten alloys are known for their high impact resistance, which is important for applications requiring toughness and durability against sudden loads or impacts.
It's important to note that the mechanical properties of tungsten alloy plates can be tailored through adjustments in alloy composition, heat treatment processes, and manufacturing techniques. Specific properties can also vary among different grades and suppliers, so detailed technical specifications should be obtained from manufacturers or suppliers when selecting tungsten alloy plates for specific applications.
