Copper nut

High lead tin bronze nut, wear-resistant copper nut, environmentally friendly recyclable copper nut. This product takes the excellent electrolytic copper as the matrix, mixes the tin ingot and the lead ingot according to the national standard proportion, forms the 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 to50MPaIt shows excellent flexibility and is the first choice for high-speed running machinery.
