Abstract

The invention discloses a Babbitt metal wire and a preparation technology thereof, and relates to the technical field of mechanical materials. The Babbitt metal wire comprises the following raw material ingredients in parts by weight: 7-18% of Sb, 3-8% of Cu, 0.0001-0.005% of Au, 0.0001-0.01% of Ni and the balance of Sn and trace elements including Cr, Mo and W. A raw material ingredient proportion of the Babbitt metal wire is regulated, the trace elements are added, the flexibility and the metallographic structure of the Babbitt metal which is finally smelted can be greatly improved, a situation that the Babbitt metal is free from a fracture phenomenon when the Babbitt metal is pulled to form wires can be guaranteed, and the flexibility and the strength of the Babbitt metal wire are improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical materials, and in particular relates to a Babbitt wire and a preparation process of the Babbitt wire. Background technique [0002] Babbitt is the most widely known bearing material, a tin- and lead-based bearing alloy with antifriction properties. Babbitt alloys are mainly used in bearing pads, bearings, bushings and bushings of large mechanical spindles. However, the existing babbitt alloy has the characteristics of poor flexibility, so frequent fractures will occur during wire drawing, which makes it difficult to make babbitt alloy into wire shape. Therefore, in view of this technical problem, a Babbitt wire and its preparation process. Contents of the invention [0003] The object of the present invention is to provide a babbitt wire and its preparation process, so as to solve the problem that the babbitt alloy made by the existing technology has poor flexibility and strength and is dif...
