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 fast-growing ships and ocean engineering

The invention discloses a high-phosphorus copper alloy for ocean engineering, which is prepared from the following raw materials in parts by weight: 3-8% of phosphorus, 6-8% of tin, 3-8% of copper, 6-8% of iron, 10-15% of defoaming agent, 3-8% of deionized water, 1-5% of adhesive, 1-5% of corrosion inhibitor and 1-5% of dispersing agent. The manufacturing method combines a high-temperature low-speed alloy pig casting process and a vacuum bright alloy pig low-temperature annealing process, changes the grain structure of the alloy pig, and can effectively prevent the alloy pig from cracking due to overhigh hardness or brittleness during extrusion.
Description
technical field [0001] The invention relates to the field of alloy rods, in particular to a high-phosphorus copper alloy for marine engineering. 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] Aiming at the deficiencies of the prior art, the technical problem to be solved by the present invention...
