Monel alloy bar, tube and wire material cold drawing lubricant composition

Abstract

The invention discloses a monel alloy bar, tube and wire material cold drawing lubricant composition. The monel alloy bar, tube and wire material cold drawing lubricant composition adopts HVIW 650 base oil as base oil which is matched with multiple additives such as an antiwear agent, an extreme pressure agent, an oiliness agent, a friction modifier, an antioxidant, an antioxidation preservative, an anti-foaming agent and an auxiliary agent. The monel alloy bar, tube and wire material cold drawing lubricant composition can be directly used in the lubricating process of monel alloy bar, tube and wire material cold drawing and has the advantages that the good lubricity, cooling property, wettability, liquidity and anti-rust property are achieved, the strength and thickness of an oil film in a deformation zone are improved, the friction coefficients are decreased, and the oil film strength and thickness properties are kept stable; the adhesivity is high, and the antiwear property, the viscosity-temperature property and the washing property are good; the extreme pressure property is high, and therefore adhesion and wear of drawing equipment and moulds are reduced; smaller flow shear stress exists, therefore, the surface finish and specification precision of machined monel alloy bar, tube and wire materials are improved, and oil spots and defects on the surface of a drawing profile are reduced.

Description

technical field [0001] The invention belongs to the field of metal processing lubricants, in particular to a lubricant composition for cold drawing of monel alloy rods and tubes. Background technique [0002] Monel alloy, also known as copper-nickel alloy, is an alloy based on metallic nickel and adding copper, iron, manganese and other elements. It has good corrosion resistance and is silvery white, suitable for edge wire material. Its main products are Monel 500, 401, 404 and Monel R-405, R-500 and other models.
