Abstract
The invention relates to novel corrosion resistant copper-based alloy which comprises the following components by weight: 37.5-39% of zinc, 1.0-2.5% of lead, 0.5-1.5% of aluminium, 0.005-0.01% of boron and the balance of copper. The copper-based alloy has similar physical properties to current nickel copper or zinc copper alloy, and has higher corrosion resistance than current nickel copper or zinc copper alloy.
Description
Technical field
The invention belongs to field of alloy material, particularly relate to a kind of novel corrosion copper base alloy.
Background technology
In existing brass work, widespread use be German silver, be widely used because having the good physical and chemical performances such as beautiful outward appearance, face high temperature.But existing use, although in this class copper alloy, chemistry ripple alive is lower than metals such as iron, when being applied in water pipe or water tap and copper valve, too can corrosion.Therefore there is technology to adopt and to add nickel to improve corrosion resistance in copper alloy.Therefore develop Alpaka, this copper alloy has great raising aspect corrosion resistance, but the shortcoming that can't overcome is also arranged, and the amount that is exactly the nickel that uses in this copper base alloy is relatively high, at more than 5% of alloy total amount.Compare with copper because of the price of nickel and want high 8-12 doubly, although can realize that the erosion resistance cost is also relatively high.
Develop a kind of can high corrosion resistance can and the relatively low copper base alloy of cost be the direction that those skilled in the art make great efforts.The contriver relies on the many years of experience of this area, through steadfast and assiduous effort, proposes a kind of copper-based alloy material that can overcome above-mentioned shortcoming.
Summary of the invention
To the objective of the invention is in order reducing production costs, to have the usage quantity of abandoning nickel under the corrosion resistance nature prerequisite, an environmentally friendly alloy material what guarantee copper base alloy.
The present invention is achieved by the following technical solutions:
A kind of novel corrosion resistant copper base alloy includes zinc, the lead of 1.0-2.5%, the aluminium of 0.5-1.5%, the boron of 0.005-0.01% and the copper of surplus of 37.5-39% by weight percentage in this alloy.
Furthermore, include by weight percentage the zinc of 38-39% in described copper base alloy, the lead of 1.5-2.0%, the aluminium of 0.5-1.0%, the boron of 0.005-0.01% and the copper of surplus.
The invention has the beneficial effects as follows:
By the present invention, stopped the usage quantity of nickel, also reduced production cost, this alloy is compared with the performance of Alpaka simultaneously, has the high corrosion resistance energy, does not re-use nickel in alloy, has reduced environmental disruption.
Embodiment
Below by embodiment, describe the specific embodiment of the present invention in detail.Embodiment proposed by the invention only is used for explaining enforcement of the present invention and can not be used for being interpreted as to be that the present invention is limited.
