Description
Affiliated technical field
The invention belongs to the non-ferrous metal manufacture field, relate to a kind of silicomanganese Cu alloy material and process for making thereof specifically.
Background technology
Axial plunger pump is the core Hydraulic Elements of hydraulic efficiency system.Along with the continuous progress of aeronautical and space technology and the development of modern project mechanical skill, the hydro-pump that produces hydraulic power has been proposed the requirement of high-performance, high reliability, not only require hydro-pump to have characteristics such as volume is little, in light weight, compact construction, and require hydro-pump can long term operation (to be generally 24～32Mpa), (can to reach more than the 6000r/min) at a high speed, under the high temperature severe condition such as (but non-stop run are 200 ℃ of oil temperature), and very high volumetric efficiency and total efficiency will be arranged at high pressure.This just makes that the vital part operating mode such as rotor, plunger, oil distribution casing of hydro-pump is more abominable, thereby vital friction pair pairing material has been proposed very harsh requirement.
As the rotor and the oil distribution casing of one of hydro-pump core component, be vital a pair of friction pair in the hydro-pump, and the copper alloy piston shoes in the plunger part that matches, their life-span has determined the work-ing life and the reliability of its place equipment and engineering machinery.At present China does not also have the material that can meet the demands fully.
The documents of coming out by retrieval has: publication number: 1462814 disclosed " polycomponent wearable brass alloy and tube forming method thereof " patent of invention, contain Cu, AI, Mn, Si, Fe in its alloy material and add rare earth, mainly be applicable to the synchro converter ring material.
Publication number: 1092817 disclosed " high-strength wear-resistant complex brass alloy and thermal treatment process thereof " patent of invention, contain Cu, AI, Mn, Si, Fe in its alloy material, can substitute tinbronze, xantal and other wear resistant brass.
Publication number: 1710127 disclosed " a kind of preparation method of high-strength wear-resistant brass pipe " patent of invention, contain Cu, Zn, Fe, Ni, Mn, Co, Si, Cr, AI in its alloy material, the alloy system that comes from different backgrounds and possess different abilities, it also is to be applicable to the synchro converter ring material.
Above-mentioned three Albatra metal-materials all contain the AI component element that reduces alloy plasticity when improving alloy strength and hardness significantly, do not contain the Pb element.All do not satisfy the continuous progress of present aeronautical and space technology and the development of modern project mechanical skill.
Summary of the invention
For overcoming the deficiencies in the prior art, the technical program provides a kind of a kind of silicomanganese Cu alloy material and process for making thereof that adopts interpolation Mn, Si, Pb alloying element to be made on Cu-Zn binary alloy basis.
For achieving the above object, the present invention adopts following technical scheme:
A kind of silicomanganese Cu alloy material, its metal ingredient content is: adopt interpolation Mn, Si, Pb alloying element to be made into a kind of silicomanganese copper alloy on Cu-Zn binary alloy basis, its alloy material component is: Cu:55～63%, Mn:1.2～4.2%, Si:0.1～2.5%, Pb:0.1～2.5%, Zn: be surplus.
