Drawing method of an aluminum tube drawing lubricant and aluminum tube

摘要

PROBLEM TO BE SOLVED: To provide an aluminum pipe-drawing lubricating oil having excellent lubricity and capable of conducting draw processing at a low cost, and to provide a method for drawing the aluminum pipe.;SOLUTION: This aluminum pipe-drawing lubricating oil is used in the draw processing of the aluminum pipe. The method for drawing the aluminum pipe uses the lubricating oil. The aluminum pipe drawing lubricating oil contains a base oil and carnauba. The base oil comprises one or more kinds selected from a mineral oil, an unhydrogenated or hydrogenated polyisobutylene, and an isoparaffin. The aluminum pipe-drawing lubricating oil contains the carnauba in an amount of 0.05-5.0 wt.%. Further, the aluminum pipe-drawing lubricating oil has dynamic viscosity of 5-50,000 mm²/s at a temperature of 40°C.;COPYRIGHT: (C)2006,JPO&NCIPI
