Abstract

The invention discloses an alloy material and particularly relates to an alloy material CuSn10Bi3 used for a bearing bush base layer. The alloy material CuSn10Bi3 is characterized by being prepared from the following components in percentage by weight: 2.8%-3.6% of Bi, 9.0%-11.0% of Sn, 0.03% of P and the balance of Cu. The alloy material can be used for completely replacing the strength, the wear resistance and other performances of a traditional bearing bush base layer containing lead, and removing polluting metal, so that the production and utilization cleanness is ensured.

Description

Technical field [0001] The invention relates to an alloy material, in particular to an alloy material CuSn10Bi3 for the base layer of a bearing bush. Background technique [0002] At present, the standard bearing material is divided into two layers from the inside to the outside: the steel back and the bronze base layer sintered on the steel back. The bronze base layer is the working surface of the bearing. The solid bearing surface is used to withstand the load on the bearing during use. The bearing surface must also have wear resistance and anti-seize properties. To achieve this effect, additional bronze alloys are usually added. The alloy composition, especially the addition of lead, was the most important lubricant for bearing alloys in the past. In the past, the most representative material for the bronze base layer was CuPb10Sn10. However, due to environmental protection requirements, various bearing manufacturers are currently studying lead substitutes, but in the applica...
