Problems solved by technology

In the currently commonly used phosphor bronze, the phosphorus content is generally about 0.1%. With the development of industry, due to the low phosphorus content, the elasticity and wear resistance of this kind of phosphor bronze cannot meet the requirements of high-end technical elastic components at home and abroad. In particular, it cannot meet the needs of my country's rapidly developing ships and ocean engineering

Abstract

A wear-resisting high-phosphorus copper alloy for ships and offshore engineering and a high-phosphorus copper alloy rod made of the alloy. The alloy comprises the following components in percentage by weight: 0.6-0.8% of phosphorus, 6-8% of tin and 91.2-93.4% of copper. The conventional phosphorus content is increased to about 0.7% from common 0.1%, so as to enhance the elasticity and the wear resistance of the alloy. Furthermore, the production method of the high-phosphorus copper alloy is further provided. The method adopts a high-temperature low-speed alloy ingot casting method and a vacuum brightness alloy ingot low-temperature annealing method, so as to change the grain structure of an alloy ingot, thereby effectively preventing the high-phosphorus copper alloy from being cracked when the high-phosphorus copper alloy is too hard or too crisp in an extruding process.

Description

technical field [0001] The invention relates to the field of alloy rods, in particular to a wear-resistant high-phosphorus copper alloy for ships and marine engineering, an alloy rod made of the alloy and a manufacturing method thereof. Background technique [0002] Phosphor bronze is a commonly used wear-resistant part and elastic element in ships and marine engineering. It is used to manufacture elastic parts that work under medium load and stroke sliding speed, such as gaskets, bearings, springs, shrapnel, etc. In the currently commonly used phosphor bronze, the phosphorus content is generally about 0.1%. With the development of industry, due to the low phosphorus content, the elasticity and wear resistance of this kind of phosphor bronze cannot meet the requirements of high-end technical elastic components at home and abroad. In particular, it cannot meet the needs of my country's fast-growing ships and ocean engineering. Contents of the invention [0003] The object o...
