Description
Technical field
The invention belongs to technical field of alloy material, more particularly, to a kind of Alpaka alloy and its component.
Background technique
Alpaka is the acid bronze alloy using nickel as main adding elements, is silvery white in color, and has metallic luster, therefore named Alpaka.
Can be infinitely dissolved each other between cupro-nickel, to form continuous solid solution, though that is, mutual ratio how much, and permanent is the single-phase conjunction of α-
Gold.It is fused into red metal when nickel, when content is more than 16% or more, the alloy color of generation just becomes pure white as silver-colored, and nickel content is got over
Height, color are whiter.The content of nickel is generally 25% in Alpaka.Pure copper plus nickel can significantly improve intensity, corrosion resistance, hardness, electricity
Resistance and pyroelectricity, and reduce temperature coefficient of resistivity.Therefore Alpaka is all different compared with the mechanical performance of other copper alloys, physical property
It is often good, ductility is good, hardness is high, it is in beautiful color, corrosion-resistant, rich in deep drawability, be widely used in shipbuilding, petroleum
The fields such as work, electric appliance, instrument, medical instrument, daily necessities, craftwork, and also it is important resistance and thermocouple metal.Alpaka
The shortcomings that be that main adding elements-nickel belongs to rare strategic materials, price is more expensive.
For example, Chinese patent literature disclose a kind of ferrimanganic copper-nickel tube preparation method [application number:
200910185341.X], the weight percent of the ferrimanganic copper-nickel tube each element are as follows: nickel 29-32%, manganese 1.5-2.5%, iron
1.7-2.3%, mischmetal 0.008%, surplus are cathode copper, and the summation of each element is 100%.The mischmetal by lanthanum,
Cerium and yttrium are by lanthanum: cerium: yttrium=2: 2: 1 weight ratio mixes.Preparation method comprises the following steps that: take cathode copper,
Nickel, manganese and iron are placed in low-frequency electric furnace, and heating is vibrated, and mischmetal is added in melting, are cast using the method for horizontal casting
Cause solid billet；Heating, is squeezed into shell；Rolling；It stretches；Pickling；Multi-pass stretching is carried out, until finished product, finished product move back
Fire.The present invention can be improved the surface quality of billet, and refining alloy crystal grain, mention due to being added to mischmetal in the alloy
High cold working performance can add better manganese and iron in the alloy, and high manganese high-speed rail can greatly improve ferrimanganic copper-nickel tube
Corrosion-resistant and flushing resistance.
