The maximum working temperature of aluminum rivets depends on the type and material of aluminum alloy. Generally speaking, aluminum rivets have good strength, hardness and toughness at low temperature, but they are easy to soften and deform or lose strength at high temperature. According to relevant data, the melting point of ordinary aluminum alloy is usually around 500℃, while the loosening temperature of aluminum rivets is generally below 200℃. Therefore, the maximum working temperature of aluminum rivets should generally not exceed 200℃, otherwise it will cause looseness, cracks or other damage. It should be noted that the use of aluminum rivets in high temperature environment is affected by many factors, such as gas, pressure, vibration, cyclic thermal expansion and cold contraction, and the specific maximum working temperature needs to be evaluated and confirmed according to the actual situation.
