Abstract

The invention provides an antimony-added high-tin bronze alloy for high-speed railway equipment and an antimony-added high-tin bronze alloy rod manufactured by the alloy. The alloy components comprise antimony, tin and copper, wherein the components of the alloy are as follows by weight percentage: 1-3% of the antimony, 8-10% of the tin and 87-91% of the copper. According to the antimony-added high-tin bronze alloy for high-speed railway equipment and the alloy rod manufactured by the alloy, disclosed by the invention, the traditional lead element is replaced by the antimony element, so that not only can the environment-friendly performance of the alloy and the alloy rod be improved, but also the hardness of the alloy and the alloy rod can be greatly improved; and the alloy harness can be improved to 110-120 HBS from the previous 70-80 HBS and the wear resistance can be obviously improved.

Description

technical field [0001] The invention relates to the field of alloy rods, in particular to an antimony-added high-tin bronze alloy for high-speed railway equipment, an alloy rod made of the alloy and a manufacturing method thereof. Background technique [0002] Tin bronze is the non-ferrous metal alloy with the smallest casting shrinkage rate. It is used to produce castings with complex shapes, clear outlines and low air tightness requirements. Tin bronze is very resistant to corrosion in the atmosphere, sea water, fresh water and steam, and is widely used in various Wear-resistant bearing bushes, bushings, flanges and gears, etc., especially for high-speed railway equipment. In order to improve the easy-cutting performance of high-tin bronze alloy rods, lead elements are often added to the bars. The high-tin bronze alloy rods after adding lead have high wear resistance and are easy to cut and are widely used. However, lead-containing high-tin bronze alloy rods will have an ...
