 Copper nuts are defined as nuts made of copper (usually lead brass, such as H59, H62). The main copper nuts we come into contact with are hexagonal nuts or other copper nuts matching bolts.

  So why use copper nuts in daily production activities? Because copper nuts are not easy to rust, anti-corrosion, easy to heat conduction and strong electrical conductivity, they are generally used in rust-proof, high temperature, electric conductivity, heat conduction and other use environments, such as taps, valves, electrical switches and so on.

  Another major use of copper nuts is injection moulding, which is heated and embedded in plastic parts or directly moulded.

  Brass has good thermal conductivity. If copper nuts are embedded after heating, on the one hand, copper nuts can quickly heat up and speed up work efficiency; on the other hand, copper nuts after heating can quickly transmit heat to plastic parts, so that the periphery of plastic holes becomes soft, which is conducive to pressing into holes; then, if injection moulding is used. What's the effect? As we all know, the melting point of PA/NYLOY/PET is above 200 C. The temperature of copper nut increases rapidly when it is melted into plastic parts. After injection moulding, the plastic body cools rapidly and crystallizes and hardens. If the temperature of copper nut is still high, what will be the result? Clever you must have guessed, the result is that the place where the copper nut contacts the plastic parts is loosened or cracked. So copper nuts are used in injection moulding instead of steel nuts.
