Wear-resistant copper nut, environmental recyclable copper nut. Using excellent electrolytic copper as matrix, tin ingot and lead ingot are mixed according to the national standard proportion to form high wear-resistant self-lubricating copper alloy material. In the absence of lubricants and water lubricants, it exhibits excellent sliding and self-lubricating properties. Under the load of high-speed rotation and rocking motion, the impact load is up to40MPaIt shows excellent flexibility and is the first choice for medium and low speed operation machinery.
