| titleOfInvention | A lead-free nickel-free environmental protection glasses copper needle |
| abstract | The invention provides a lead-free and nickel-free environment-friendly copper needle for glasses. The elements of copper, iron, nickel, palladium, molybdenum, tin, manganese, rhodium and zinc are used as special brass materials for manufacturing the copper needle. Molybdenum, tin, manganese and rhodium can improve the strength of brass, so that the copper needle can withstand greater force without plastic deformation. The alloy does not contain lead, so long-term wear will not cause lead poisoning, and the content of nickel is extremely high. Low, does not reach the release amount of nickel, and it will not cause harm to people. The raw materials are melted at high temperature to make bars, and then the bars are extruded through a die, processed by a milling cutter, punched by a pusher, and polished by a polishing machine. , welding machine welding and other machining to make the copper rod into the finished product of the copper needle for glasses, the surface of the finished product is treated by tin-cobalt alloy electroplating, so that the finished product has a bright metal texture, and is not easy to wear, and it will not cause corrosion and rust when worn for a long time. |
