Abstract
The invention relates to a high-toughness copper alloy which comprises the following elements in parts by weight: 0.19-0.22 part of C, 6-7.5 parts of Mn, 10-12 parts of Si, 0.8-1.2 parts of Cr, 3-5 parts of Fe, 20-25 parts of Al, 5-8 parts of Ni, 8-14 parts of Zn and the balance of Cu and unremovable impurities. The high-performance copper alloy material is obtained by the following steps: heating; molding; quenching by waste heat; tempering at medium-temperature; and finally molding a final shape of a product. The high-toughness copper alloy provided by the invention has the beneficial effects that the high-toughness copper alloy is good in elasticity, high in toughness and suitable for normal work under a loading environment; the copper alloy has relatively high yield strength for manufacturing a spring material, is relatively long in service life, and is free of brittle failure under an extremely severe condition; moreover, the alloy is high in cost performance and suitable for being popularized and used in a large area in the industrial manufacturing field.
Description
Technical field
The present invention relates to a kind of steel alloy, especially a kind of high tenacity copper alloy.
Background technology
Copper is one of ancient metal of finding the earliest of the mankind, and before more than 3,000 years, the mankind just bring into use copper.The copper of occurring in nature is divided into native copper, copper oxide ore and copper-sulphide ores.The reserves of native copper and cupric oxide are few, now in the world the copper of more than 80% from copper-sulphide ores refining out, this ore copper content is extremely low, generally at about 2-3%.Metallic copper can form alloy with metals such as zinc, tin, lead, manganese, cobalt, nickel, aluminium, iron, and the alloy of formation is mainly divided into three classes: brass is copper zinc alloy, and bronze is gunmetal, and copper-nickel alloy is copper cobalt-nickel alloy.
Copper alloy should have excellent over-all properties, as mechanical property (particularly elastic limit, breakdown point, yield tensile ratio), elasticity attenuation resistance can (namely elastoresistance goes down performance, also known as relaxation resistance), fatigue property, hardening capacity, physical and chemical performance (heat-resisting, low temperature resistant, anti-oxidant, corrosion-resistant etc.).High tenacity copper alloy is generally used for and makes copper spring piece, and when making high tenacity copper alloy, technical requirements is higher, and technology really up to the mark directly determines the height of quality.Easily there is brittle failure in current copper spring piece, also need larger lifting degree to meet modern industry demand under the mal-condition of pole.
Summary of the invention
The invention provides a kind of high tenacity copper alloy.
The present invention is directed to the technical scheme that above-mentioned technological deficiency proposes is:
A kind of high tenacity copper alloy, adding each element wt part is: C:0.19-0.22 part, Mn:6-7.5 part, Si:10-12 part, Cr:0.8-1.2 part, Fe:3-5 part, Al:20-25 part, Ni:5-8 part, Zn:8-14 part, all the other are Cu and not removable impurity, and described high-performance copper alloy material is through heating, shaping, immediate quenching, average tempering, finally carry out the shaping of product net shape.
B:0.5-0.8 part can also be added.
Pb:0.5-0.8 part can also be added.
The invention has the beneficial effects as follows: good springiness, toughness is high, work normally under being adapted at load environment, to manufacture spring materials, there is higher yield strength, and there is the longer life-span, and can not occur the problem of brittle failure under the mal-condition of pole, and its cost performance is high, the spread being applicable to industry manufacture field uses.
