Abstract
The invention discloses copper-magnesium alloy and a preparation method thereof. The copper-magnesium alloy comprises the following constituents by weight percent: 4.5 to 8.5wt percent of Mg, 0.4 to 0.6wt percent of Ti, 0.3 to 0.5wt percent of Cr, 0.07 to 0.1wt percent of Sn, 0.06 to 0.09wt percent of Ge, and the balance of copper. The preparation method comprises the steps of performing high-temperature melting in a high-temperature smelting furnace, feeding the constituents, and then cooling the constituents, so as to obtain the copper-magnesium alloy. The copper-magnesium alloy has excellent elongation.
Description
Technical field
The present invention relates to a kind of Alloy And Preparation Method, particularly relate to a kind of copper-magnesium alloy and preparation method thereof.
Background technology
The application of copper alloy is comparatively extensive, different metallic elements is mixed to rear high melt with copper, can obtain some additional effects, has effectively overcome some problems.The unit elongation of alloy is a study hotspot of industry always, and the unit elongation that promotes copper alloy is a target of research.The unit elongation of the metal mixed material of conventional copper alloy, in 10% left and right, can not meet the needs under some special purposes.By different metals and copper are carried out to mixed smelting, likely can further improve the unit elongation of copper alloy.
Summary of the invention
The technical problem solving: the conventional lower problem of copper alloy unit elongation.
Technical scheme: the invention discloses a kind of copper-magnesium alloy, copper-magnesium alloy is comprised of according to weight ratio following composition: Mg is that 4.5wt%～8.5wt%, Ti are that 0.4wt%～0.6wt%, Cr are that 0.3wt%～0.5wt%, Sn are that 0.07wt%～0.1wt%, Ge are that 0.06wt%～0.09wt%, surplus are copper.
A preparation method for copper-magnesium alloy, comprises the following steps: (1) high temperature melting furnace Temperature Setting is 950 ℃; (2) to adding Mg in high temperature melting furnace, be that 45kg～85kg, Ti are that 4kg～6kg, Cr are 3kg～5kg; (3) to adding powdered carbon in high temperature melting furnace, be 5kg again; (4) high temperature melting furnace is warming up to after 1800 ℃, adding Sn is that 0.7kg～1kg, Ge are that 0.6kg～0.9kg, copper are 902.1kg～946.7kg, melting 7～10h; (5) be cooled to room temperature after being finally cast into copper alloy ingot, obtain copper-magnesium alloy.
During high melt, add the weight of Mg to be preferably 85kg.
During high melt, add the weight of Ti to be preferably 6kg.
During high melt, add the weight of Cr to be preferably 5kg.
Beneficial effect: the copper-magnesium alloy that the present invention prepares has very higher unit elongation, the unit elongation of copper-magnesium alloy is 23% to 24%, can meet the demand of some special dimensions.
