Abstract
The invention relates to low-nickel copper-based alloy, which comprises (by weight percentage) zinc 35-36.5, nickel 1.5-2.0, lead 2.5-4.0, tin 0.5-1.5, aluminum 0.3-1.0, and copper in balance. The copper-based alloy has similar physical properties to nickel-copper or zinc-copper alloy, but the consumption of nickel is reduced by near 70%.
Description
Technical field
The invention belongs to field of alloy material, particularly relate to a kind of low ambrose alloy base alloy.
Background technology
In the existing brass work, widespread use be German silver and Alpaka, because of have beautiful appearance, good physical and chemical performance such as high temperature resistant, corrosion-resistant is widely used.But in existing this type copper alloy that uses; All use a certain amount of nickel more all at more than 5% of weight ratio with the consumption of realizing nickel in anticorrosion effect, the especially Alpaka, and the selling at exorbitant prices of nickel; Make the price of this type alloy be difficult to reduce, bring very big cost pressure to manufacturing enterprise.Because of nickel environment is had certain harm simultaneously, the usage quantity that reduces nickel also is the protection to environment.Therefore press for a kind of performance that can guarantee existing German silver or Alpaka of exploitation, the copper alloy that the usage quantity of minimizing nickel can reduce cost again.
Summary of the invention
The objective of the invention is under the performance prerequisite that guarantees copper base alloy, to reduce the usage quantity of nickel, environmentally friendly alloy material in order to reduce production costs.
The present invention realizes through following technical scheme:
A kind of low ambrose alloy base alloy includes zinc, the nickel of 1.5-2.0%, the lead of 2.5-4.0%, the tin of 0.5-1.5%, the aluminium of 0.3-1.0% and the copper of surplus of 35-36.5% by weight percentage in this alloy.
Further, the zinc, the nickel of 1.5-1.8%, the lead of 2.5-3.0%, the tin of 0.5-1.0%, the aluminium of 0.3-1.0% and the copper of surplus that include 36-36.5% in the described low ambrose alloy base alloy by weight percentage.
The invention has the beneficial effects as follows:
Through the present invention, reduced the usage quantity of nickel, also reduced production cost, this alloy is as broad as long basically with the performance of former German silver and Alpaka simultaneously, and because of reducing the usage quantity of nickel, has reduced environment damage.
Embodiment
Below, describe embodiment of the present invention in detail through embodiment.It is that the present invention is limited that embodiment proposed by the invention only is used to explain enforcement of the present invention and can not be used to be interpreted as.
Embodiment 1
A kind of low ambrose alloy base alloy includes 35% zinc, 1.5% nickel, 2.5% lead, 0.5% tin, 1.0% aluminium and the copper of surplus by weight percentage in this alloy.Among the embodiment that below the present invention, is proposed, others are all identical except that the shared per-cent difference of each element.The manufacturing processed of said alloy is, the zinc of weighing in proportion, nickel, aluminium and copper are put into smelting furnace, in 1050-1250 degree centigrade of scope, melts, and adds lead and tin then, under the situation of 850-950 degree centigrade of insulation, carries out subsequent technique.
With the copper base alloy of filling a prescription and producing according to this, identical with existing ambrose alloy or platina after cooling in physicals, but the consumption of nickel is 30% of existing ambrose alloy or zinc-copper.
In following examples of the present invention, in the physicals all similar, but the consumption of nickel has reduced nearly 70% to the copper base alloy of production with existing ambrose alloy or platina.
