Embodiment Construction

[0012] A method for preparing an anti-fatigue copper alloy wire for an automobile elastic element, comprising the following steps:

[0013] (1) Put the copper block into the melting furnace and raise the temperature to 1260°C to melt, then raise the temperature to 1320°C, add the relevant alloy ingredients, stir evenly, after all the melting, adjust the temperature to 1280°C and add refining agent to refine for 25 minutes, then grill After holding the slag for 20 minutes; then conduct a rapid chemical analysis of the copper alloy liquid before the furnace, so that the weight percentage of each element in the copper alloy liquid meets the following requirements: Al 2-4, Sn 1.2-2.4, Ni 0.5-1.5, Zn 0.6- 0.12, Sb 0.4-0.8, Bi 0.25-0.35, As 0.03-0.06, B 0.015-0.025, Pd 0.01-0.02, Ru 0.005-0.015, Er 0.02-0.03, Tb 0.015-0.025, P 0.005-0.01, the balance is Copper and unavoidable impurities; after analysis, adjust the feed according to the weight percentage of each component in the form...

Abstract

The invention discloses a making method of an anti-fatigue copper alloy wire for an automobile elastic element. The anti-fatigue copper alloy wire comprises 2-4wt% of Al, 1.2-2.4wt% of Sn, 0.5-1.5wt% of Ni, 0.6-0.12wt% of Zn, 0.4-0.8wt% of Sb, 0.25-0.35wt% of Bi, 0.03-0.06wt% of As, 0.015-0.025wt% of B, 0.01-0.02wt% of Pd, 0.005-0.015wt% of Ru, 0.02-0.03wt% of Er, 0.015-0.025wt% of Tb, 0.005-0.01wt% of P, and the balance Cu and inevitable impurities. The cooper alloy wire has the advantages of good fatigue resistance, no fracture after long term use, long service life, good wear resistance, high mechanical strength, high fatigue ageing resistance, low processing cost and the like.

Description

technical field [0001] The invention relates to a preparation method of an anti-fatigue copper alloy wire for automobile elastic components, belonging to the technical field of copper alloy manufacturing. Background technique [0002] Copper alloy is an important material for the national economy.
