Wude alloy consists of 50% bismuth, 25% lead, 12.5% tin and 12.5% cadmium. Wude alloy, also known as wood alloy, is a gray and shiny metal, with bismuth as the main component and low melting point. When the current in the circuit is too large and the temperature is too high, it will fuse and protect the electrical equipment.
Wude alloy is a low melting point alloy based on metallic bismuth. The strength of Wude alloy is not high, only 30MPa at room temperature, 3% elongation and very low hardness, only HBS25.
Brief introduction of Wude alloy
Wude alloy is made of 50% bismuth, 25% lead, 12.5% tin and 12.5% cadmium. Its melting point is 70℃, which is lower than that of all metals that are solid under standard conditions.
Spanish Uroa and Wu De discovered that platinum mainly exists in free state and alloy state in 1935 and 194 1 year respectively. Therefore, in order to commemorate wood, people named this special alloy wood alloy.
Wood alloy is used to make circuit fuses, automatic fire extinguishing and explosion-proof safety devices.
